Fixin’ a Hole where the Skunk gets in, and stop Her from Going in to Den… (or a Raccoon)

Now is the time to inspect and maintain your home and yard to ensure that, come spring, you won’t have any unwanted wild animals raising their families in your space.

Every year Humboldt Wildlife Care Center raises orphaned skunks and raccoons, most of whom need not have been orphaned. Typically the mother was trapped and relocated when homeowners heard or saw activity in the spring, not realizing they were separating a young family and leaving 3-5 infants alone to die unless their screams for help are heard and they are rescued in time.

Wild mothers look for places that are warm, dark, quiet and protected to give birth and raise their babies. Once the babies are old enough (2-3months) they will follow their mothers out at night and the den will be abandoned until next spring. In urban environments, Raccoons may den under the house, often in the void around the bathtub, or in the attic where the entrance is hard to access and easy to defend from predators. Skunks often den under sheds or woodpiles

Walk around your property pay careful attention to these areas:

  • Foundation vents: make sure all vents are covered with metal screen. Gently push on all vents to ensure the screen is firmly attached. Any missing screens, broken screens, or rusty screens should be replaced.
  • Signs of digging:  especially around foundation, sheds, and porches
  • Mobile home or porch skirting: Make sure there are no missing boards or openings that will allow access to animals. Even small holes should be patched.
  • Attic vents and roof overhangs: Make sure vents are screened and all openings are securely covered.
  • Chimney: Make sure the chimney cap didn’t blow off in the winter storms. Bats and swifts roost or nest in chimneys and other animals could fall in and become trapped.
  • Roof: Trim back any tree branches that may provide roof access to raccoons. Never trim branches during nesting season, though!

Securing these access points will prevent wild mothers from using your home as their nursery. Since these dens are only used to raise young, winter is the best time to make any necessary repairs because it is unlikely that any animals will be trapped inside. If you do suspect an animal is actively using an opening call us at HWCC (707) 822-8839, so we can help determine when it is safe to close the opening.

A little time spent maintaining your home now can help prevent a lot of suffering for your wild neighbors come spring.

An orphaned Raccoon is released after 4 months in care. It’s better for everyone if Mama raises her own babies.

If raccoons or skunks do end up denning under your home, take heart in knowing they won’t be there for long. If you are able to tolerate their presence for a few months they will be on their way before long.

If you are not able to tolerate their presence, do NOT set a trap and do NOT call a pest control company. It is possible to convince the mother to move her babies to another den away from your home and we can help humanely resolve the situation in a manner that satisfies you and the animals. Call us and we will be happy to walk you through the steps that will work best for your situation.

As always, thank you! Your support not only helps us provide excellent care for our wild neighbors in need, but also helps us prevent orphanings and injuries in the first place! Promoting co-existence with our wild neighbors is not only the right thing to do, it’s also the smart thing.

How can you mend a broken wing?

Posted on by Monte Merrick

We strive to do the best work we can, for our patients, for our community, for our Mother Earth.

We strive to improve. We strive to better translate the needs, the injuries, the desired futures of our wild patients into something that our fellow citizens of this built world can hear. It’s hard work, but not too hard. We are all allies of the wild. The wild is the first ally of us all.

Over the next few months we’ll be asking for support as we prepare for our busy and financially stressful Spring and Summer months. We need your support now. We’ll need it then. Thank you for making a difference for our wild neighbors when they’re in a jam.

A New Loon’s Year

Posted on by Monte Merrick

Our friends at Friends of the Dunes called one Monday morning in the middle of January to tell us that someone had stopped by their facility, the Humboldt Coastal Nature Center, to report a stranded Loon. We were well staffed that morning so we were able to send a couple people over to take a look. All Winter long we admit seabirds into care who are struggling, for one reason or another, and wind up on the beach in serious trouble.

Seabirds, including those like Loons, who raise their young on freshwater lakes and winter on salt water bays and near shore ocean, evolved millions of years ago to a life spent primarily on water. Dense pale feathers on their ventral surface, below the waterline, keep birds warm in the cold ocean and also provide cryptic coloring against predators from below, such as sharks, sea lions, and whales, who may have a harder time detecting the birds floating above them in the light. Another change the aquatic environment has driven in some species is the placement of the pelvis and legs far to the rear of their bodies. As foot-propelled pursuit divers, loons and grebes are dramatic examples of this adaptation. On land these kinds of birds appear very awkward, often unable to stand or walk. Relatively heavy birds, on land they can be literally stranded (stuck on a strand, i.e. beach) where they need a running start across open water to gain the speed necessary for lift. Because of this many people who find them on a beach might mistakenly think the bird is suffering a broken leg!

Typically, all of these adaptations add up to the fact that a seabird on the beach needs help. A terribly vulnerable location, only a bird with no other options would chose the beach over the water, where everything that supports life is found. Injuries, contaminants such as oils that interfere with the feathers’ waterproof insulation, and illness are common factors in stranded birds, but most often, the birds we admit from beaches are juveniles spending their first winter at sea.

Struggling to feed themselves, storms, heavy surf and the challenges of learning the ropes on the job all contribute to the failures of these birds, especially in our times, when ocean health is in a critical state. Over-fishing, agricultural waste run-off, plastic pollution, derelict fishing gear and the great onrushing disaster of climate chaos make the already challenging ocean into a rapidly unfolding disaster.

When our staff arrived at the beach in Manila, they quickly found the bird, a juvenile Pacific Loon (Gavia pacifica), high up the beach above the line of wrack that marked the highest tide. Quickly scooping him up, they brought the young bird back to Humboldt Wildlife Care Center.HWCC volunteer heads back up the dune with a young Pacific Loon safely in the box.

On the admission exam we found no real problems – just a young thin bird who’d missed to many meals. The loon was fortunate. Another day unseen and dehydration alone would have begun taking a terrible on his health. Instead, we were able to stabilize his condition and get him turned around. Within a day he was floating in one of our pools, rapidly recovering. In cases like this, fish is medicine.
Our pools are a critical part of our facility. Aquatic birds make up nearly half the patients that HWCC treats.

Typically, it takes about 3 weeks for a seabird to recover from emaciation. This bird however, was in somewhat better condition, and also individuals vary. Some just get down to the business of recovery faster, either due to relative health, certain capabilities, or any of the myriad other factors that we can sense or imagine, but may never know. In any case, after 11 days in care, this Loon was ready to go home. Besides the measurable parameters, such as body mass and red blood cell percentages that we use for all seabirds. Able to “dive like a banshee” (an in-joke here at the clinic – banshees scream; they don’t dive.), meaning when we tried to capture for an exam, he would slip beneath the water and swim laps around the pool, staying down for minutes at a time.
It’s a simple, inescapable fact that none of our procedures are done with the consent of our patient. This fact demands that we bring our A-game to all of our actions, but especially in our empathy for the indignities of our handling. Swift, gentle, decisive and accurate are the qualities we strive for in all our dealings. Acknowledging the stress and trauma of captivity that all of our patients endure so that we can mitigate their impact is an important ingredient in respecting them and providing the care they need.

So on a cool, cloudy morning we took the Loon down to the edge of Humboldt Bay for release. As soon as he hit the water, he dove, eager to rinse the stench of his caregivers from his beautiful and oceanic young feathers and get back to the business of his life, riding the wave of a second chance.

The last box this Loon will know – heading out for release.

At the release site, an HWCC volunteer lifts the Loon gently to place in the water.

And under he goes!

Back up!

And he begins to sail off, freedom and salt water and hopefully no walls confining him ever again.



Alone at last, our ex-patient starts hunting for his own fish.

So far this year we’ve already admitted over 60 of our wild neighbors, each of them desperate for care, a certain death the only other avenue. We’re committed to providing that care. We’ve built the pools; we’ve stocked the larder; we’ve trained the staff. None of these would’ve ben possible without your support. Thank you!

We’ve begun our fundraising to prepare for another busy year. We need to raise $25,000 by the end of April. This will get us through the first half of the Summer, and by then we’ll need to ask again. We hope you can help get us there! If you can, please donate today! Thank you!

Mange in Southern California Bobcats Driven by Loss of Habitat and Anti-coagulant Rodenticides

Posted on by Monte Merrick

A study of a Bobcat (Lynx rufus) population in Southern California (see attached below) published in December 2017 demonstrates that urbanization (loss of natural habitat) coupled with exposure to anti-coagulant rodenticides (ARs) has led to a significant decline in their numbers, as well as untold suffering. Habitat loss and AR exposure were shown to be significant stressors that suppress Bobcats’ immune systems and organ function, thereby increasing their susceptibility to notoedric mange.

All forms of mange are caused by a parasitic, burrowing mite. Different species of mites cause different types of mange that range in degree of seriousness. Mange is spread from animal to animal with loss of habitat presumed to cause some of the problem simply by bringing individuals into closer contact. Notoedric mange is primarily a felid (cat) and rodent disease. Notoedric mange may be a significant player in the decline of Western Gray Squirrels (Sciurus griseus), who are listed as threatened in the state of Washington, and as a state sensitive species in Oregon.

Habitat loss coupled with the toxic burden of rodenticides, which are ubiquitous in California and the world, are a terrible one-two punch that is wreaking havoc on our wild neighbors.

Quoting from the study on Bobcats:

Consequently, AR exposure may influence mortality and has population-level effects, as previous work in the focal population has revealed substantial mortality caused by mange infection. The secondary effects of anticoagulant exposure may be a worldwide, largely unrecognized problem affecting a variety of vertebrate species in human-dominated environments. (emphasis added)

Great Horned Owl Trapped in Duck Coop…

Posted on by Monte Merrick

It must have been quite the scene! The people who found this owl inside their duck coop on their property near the stateline with Oregon said that they’d seen the bird harassing one of their ducks. The next day they found her trapped inside the coop, covered in mud, with a recently eaten duck nearby.

How the Great Horned Owl (Bubo virginianus) got in the coop is a mystery. The duck was a big Muscovy, a large breed that would have been a very unusual prey species for a Great Horned Owl. While these are fairly large owls – a typical Muscovy is still nearly twice as big. Catching food isn’t supposed to be a fight to the death.

However the owl got into the coop, the people who found her could tell she needed help. They drove the owl 100 miles south to our clinic, the only permitted all species facility on the North Coast.

During the admission process, we found no obvious injuries – just a frightened, angry, filthy, wet, big female owl.

After a few days of lightly spraying her down with water indoors to help her clean herself, we moved her to an outdoor aviary. Surprisingly, she seemed unable to fly. We hadn’t been expecting that. We took another look at her wings, her shoulders, all of the parts that allow flight. Again, we found no injuries. Since it seemed that she likely was suffering from a strain or sprain, we took her back to the aviary. Time, as it often is, would be the best medicine.

Our raptor aviary (Merry Maloney Raptor House) is small compared to wide open world but it is big enough that we can assess the flight capabilities of large birds, like this Great Horned Owl.

After a few days of eating and preening, her weight was up and her feathers were in much better shape. At this time she also began making very short flights – nothing spectacular, but enough to know that she was recovering. After a week, she was actually getting from perch to perch. Twelve days after she was admitted, her power returned.

Catching a flighted patients for her release exam is a critical part of the evaluation. She passed this aspect with flying colors.

With her flight strong and her health good, it was time to take her home. Although it had been stormy for days we got a long break in the weather mid-week and we improved it with a beautiful owl’s return to her wild freedom.

Leaving the last of a long series of boxes – some no bigger than a large suitcase, some the size of our aviary, all of them a form of captivity, an insult that ends as soon as the patient has recovered. 

Bird flying away – a heartwarming sight…

After flying away from us, the Owl first stopped in this tree to reconnoiter. This release site was very close to where she had been found so the neighborhood was familiar.

After a few minutes, she took off again, into the approaching night.

Our last glimpse before she was gone, slipped into the surrounding Wild.

A beautiful winter’s night with one more of her family home again…

So often we cannot know what happened to injure our wild patients. Context clues, such as where the animal is found, and so forth, along with statistical probabilities are often all we have to go on. Regardless, we still have to treat the animal who shows up, using solid techniques and sometimes our own intuition. It’s highly rewarding work with the only real hazard being that we might fall away from our human neighbors due to how often we must put ourselves imaginatively in the shoes of our wild neighbors. Using our imaginations in concert with good science is the highest level of thought we can achieve when providing care for our patients. This is probably true for most environmental problems that we face.

No matter what methods we use, the one thing that is indispensable is your support. You keep our doors open and our lights on for our wild neighbors in a jam. Thank you!

If you’d like to help, we could use it! Please donate today! Thank you!

New Study Shows Very Common Pesticides Disrupt Migratory Birds’ Sense of Direction.

Posted on by Monte Merrick

Many songbird populations are in steep decline. These losses have many well known causes – free-roaming house cats, buildings and cars loom large as threats – yet some of the causes remain a mystery. An alarming study published November 2017 in the journal Nature has confirmed that two of the most common pesticides in widespread use in North America and elsewhere are a very significant part of the problem. The study shows that both chemicals significantly impair exposed White-crowned Sparrows (Zonotrichia leucophrys) ability to orient directionally; – a disability which would have obvious negative impact on a migrating songbird. One of the chemicals in the study also caused significant loss of body mass, also imperiling birds during migration. Impact to populations is not in the scope of this study, but the impairments that were shown, and the likelihood that these risks would be at their most threatening when Spring migration and industrial seed sowing coincide, it is easy to extrapolate the serious and tragic consequences.

Imagine landing in a freshly sown field somewhere between your gentle winter home and the fulsome days of summer – the field the only resource left after the prairies and forests were industrialized by farming – and as soon as you eat you begin to forget your way, where you were going, perhaps even why. If the poison is also causing you to starve, well, you won’t last long – a very dim bright side. In neither case will you make it out of there – make it to your destination, the place where you and your mate get about the business of bringing the next generation of your kind into the world…

A White-crowned Sparrow nestling/fledgling in care at HWCC is examined after admission. Too old to keep in the nest, too young to fly, this bird was was successfully returned to her parents. 

Songbirds moving north are on a mission – the mission of life. Exposed to these poisons, instead they stagger, lost in the vast sea of a chemically restrained Mother Earth, like Dorothy, the Tinman, the Lion, and the Scarecrow, but not done in by the poppies, but rather the chemicals that had been sprayed on them to kill all adjacent life.

For both chemicals in the study it took 2 or more weeks after their last exposure while being maintained in captivity, for the birds who were subjected to the toxin to recover their lost weight and their lost sense of direction.*** Of course, given the nature of agriculture across the so-called heart land, there is no such thing as a real-world post-exposure period of convalescence, outside of potential intervention by wildlife rehabilitators, – a shot in the dark.

White-crowned Sparrow at HWCC enjoys a mealworm before be taken back to her family.

The two pesticides in the study are both in very wide use, especially in the US, yet are also controversial for the links that have been shown between them and observed health impacts for people and wildlife. One, imidacloprid , is a neonicotinoid, such as are currently implicated as a factor in bee colony collapse disorder, among other concerns, and the other, chlorpyrifos, is an organophosphate with its own checkered past. Banned by the US Environmental Protection Agency (EPA), after a significant legal process, at the end of 2016, under the new administration, Scott Pruitt, the new head of the Trump administration’s EPA (TEPA), reversed the process of banning the pesticide.

Neonicotinoids in high concentrations have already been shown to be among the causes of population decline in insect-eating songbirds, now this study shows that even very small amounts – the amount found on one treated seed – can impair songbirds during the most critical time in their lives, when they are migrating to their breeding grounds.

The threats posed to songbirds by society are extreme. Our human built world, in multiple ways, kills songbirds in the billions annually in just the US alone!

Human-caused avian mortality ranked by deaths annually.
 https://www.fws.gov/birds/bird-enthusiasts/threats-to-birds.php

How many songbirds are killed by these two chemicals alone is not yet known. But what we do know, is that the problem is huge and the very pinnacle of executive power in this nation, at least, is unconcerned, to say the least, about the fate of wild birds. If nothing else this means that co-existing, peacefully, with our wild neighbors, and the wild in whole, is always more urgent. As long as our civilization continues to advance in the direction of death and extinction, hope lies in the actions we make locally, on the ground, literally in our own backyards.

A fledgling White-crowned Sparrow successfully reunited with parents by HWCC/BAX staff.

There are many things on the list of threats to songbirds that we can reduce as we work toward eliminating, today, right now. We can respect all nests. We can keep our cats indoors (bonus, it’s better for cats, too!!!) We can stop trimming branches during nesting season. We can plant bird friendly native plants. We can slow down when we drive and we can drive less. We can help out individuals when they’re in need. That’s the primary thing that we do – help out our individual wild neighbors whenever they get caught in a jam.

Your support makes our work possible. Even if the worst befalls us, still we’ll need to care for the innocent wild victims who suffer from of our mistakes, accidents and thoughtless greed. Our wild neighbors will always need you to help when society, in ascendancy or ruin, does its dirty work. Thank you for being here. Thank you for keeping our doors open.

 

*** For the record, the kind of experiment performed that got these results is not endorsed by Bird Ally X. The pesticides in question have been long known to disrupt the ecological systems into which they are introduced – deliberately imperiling the lives of White-crowned Sparrows, without their consent, is not a right that people have, regardless of their intentions. This information, if it is critical to have in order to make decisions, which is anything but a foregone conclusion, must be gotten in ways that don’t violate the rights of others. Study subjects have the same rights to their independent autonomy and ownership of their own bodies that humans are supposed to have .

It’s hard to find the ground to stand on which might allow us to see whose freedom is meaningful and whose is not. We need a much clearer view of the world and our place within the living network we share. It is a common belief in public service that citizens are to be protected from “false negatives” – that is, finding no harm detected where harm does in fact exist. Our modern history is rife with examples of false negatives being foisted on an unsuspecting public with disastrous result: automobile safety, tobacco use, radioactive fallout, DDT, the list is endless. False positives, attributing observed harm to the study object in error, may be frustrating to those who want to advance on some project, or inject the latest fad into farmed fish, but it is the proponent’s obligation to prove those positives as false – it is not the public nor the agencies charged with protecting the public’s health, well-being, and rights, mission, let alone obligation, to protect companies and governing bodies from the demands of due diligence. At least the same respect is owed to the autonomous lives of our wild neighbors. We must consider them as sentient and with the same rights of existence as our own. It is the burden of those who would capture, kill, plunder, poison, for reasons noble to foul to demonstrate that consent is not needed…

Thayer’s Gull Turns Life Around

Posted on by Monte Merrick

Every winter Humboldt Wildlife Care Center/BAX admits several gulls with injuries – usually from being struck by a vehicle. So when we got a call on the third day of the new year from someone in Eureka who’d found a gull not able to fly in her backyard, we figured it would be another case of a wing smashed in traffic. We drove over and picked up the bird, who turned out to be a juvenile Thayer’s Gull (Larus thayeri). Not the most common gull in our area, they breed high in the Arctic but are fairly regular visitors to our coast during Winter months. We’ve treated several over the years.

Once we had this bird back at our hospital, an initial examination found a bird with no obvious injuries, but definitely favoring her or his left wing – no fractured bones, no swelling, just an apparent weakness on that side, shown by an asymmetrical carriage of the wings.

We also detected that this young bird’s jaw had been fractured, but had healed in place, with a slight misalignment. The lower bill (mandible) didn’t quite sit right in the upper bill (maxilla). Although this might seem to be a minor problem, nearly all of a bird’s ability to keep their feathers in good, functional shape, critical for survival, is done using the beak. Preening – that is, cleaning, adjusting, realigning feathers that are out of place – is critical for a bird to able to withstand the elements, especially here on the North Coast with our stormy winters.

So we housed this gull, otherwise healthy, in an outdoor aviary with access to a pool. While we waited for the undetectable soft-tissue injury that was preventing flight to heal, we would learn if this gull could maintain her or his feathers in an outdoor winter setting.

The answer was yes. Through the various storms of January, our patient stayed warm, dry and looking good, feathers unruffled, spirit unflappable. S/he was a major fish enthusiast, eating everything offered in short order. Convincing a bird to eat in captivity can sometimes be challenging, but this gull knew the meaning of a plate of night smelt (Spirinchus starksi), the fish of choice that we feed most of our piscivore patients.

After 10 days, the gull began making short flights, using both wings, that gave care providers a reason for optimism. By 2 weeks, the gull was flying from perch to perch in our large aviary, clearly on the re-bound. After a few more days of strong flight in our aviary, we checked over the patient one more time. Everything looked terrific – blood values perfect, weight  normal, body condition fantastic, attitude fierce, and desire to get as far from us perfectly intact. So we put Larus thayeri one last time into a box and then into a car and down to the edge of Humboldt Bay where this bird became our patient no more forever!

You hope they go one way, but wild animals don’t care what we hope!

Dedicated volunteer says, “gull!” – Gull says, “duck!”

Landing several feet away, giving us the “look”…

And then it’s time to go…

So often with gull releases, they fly back to the release site, swoop around, check us out. Just as we are intensely interested in their world, perhaps they are also curious about ours.

Drinking the bay! Like most birds that live near saline water, gulls have a gland that allows them to eliminate the salt.

There is nothing like the sight of a patient flying away.

The injuries this gull suffered were relatively minor and really healed on their own. What we provided was a safe haven. It is very likely that the two weeks of rest needed, the two weeks of being unable to fly, would have been the end for this young bird without help. But such wasn’t the case. The gull’s collision with the casual violence of human civilization didn’t end in death because we were here. Just like everyday. And we’re here because of one reason only: your support. Thank you for keeping our doors open. You make a difference for wildlife. If you’d like to help, please donate today.

7 in 10 Endangered Spotted Owls Exposed to Rat Poison, Retail Ban Insufficient

Posted on by Monte Merrick

In 2014, the State of California banned the rat poison that had been increasingly causing sickness and death in wild animals, second generation anti-coagulant rodenticides (SGARs), sold in retail stores as D-con. Although the California Department of Fish and Wildlife had submitted an opinion that the rodenticide needed to be more tightly regulated, it still took 3 years to get the toxin off the shelves of neighborhood stores. However, the ban was not total. Commercial applicators and farmers can still buy and use this poison – and they do.

Killing rats with a slow acting poison, as it turns out, is a very effective way to spread poison through an ecosystem. Rats sick and dying from ingesting rodenticide are caught by wild predators – raccoons, bobcats, mountain lions, eagles, hawks, weasels, – anyone who eats rodents.

Now a newly published study shows that 70% of Northern Spotted Owls (Strix occidentalis) on the North Coast, in the heart of the coastal range forests, where cannabis cultivation has punched holes and created edges, tested positive for rodenticide exposure. Unfortunately, this means that our region is now close to par with the rest of California. An ongoing study in the San Francisco Bay Area undertaken by Wildcare in Marin County has found 83% (updated) of all wildlife tested to be exposed to SGARs. No doubt similar numbers are found in other states and nations.

The world is poisoned. It has been for a long time. From the the first coal mines of Appalachia through the daily spew of burned gasoline and pesticides and even radiation from Fukushima’s ongoing catastrophe, civilization has brought its poisons everywhere it expands. If our civilization lasts to colonize Mars it will bring its poisons there too. From plastics in the oceans to radioactive isotopes in milk, this news is old.

The solutions to humane and effective rodent control are many and require some thought and effort. Thought and effort are exactly what use of poisons seeks to avoid. The impacts to our world from such short-cut seeking are obvious and staggering. Still, the solutions aren’t that difficult. First, conflicts with wild animals, even non-native wild animals like Norway rats, are almost always created by a human housekeeping issue. Feeding pets outdoors, unprotected food storage, unprotected compost bins that aren’t rat-proofed, materials and debris piles around outbuildings, and more all contribute to rodent problems. Good housekeeping solves a lot of the problem. Putting up an owl box can also be useful. Encouraging raptors in your area will also help. Barn owls, Great-horned owls, Red-tailed hawks and others eat rodents for a living! If you have a problem with rats, there are myriad humane and ecologically sound resources available. (see below for resources that can help)

It’s an old formula and in many ways it’s still true: the solution to pollution is dilution. Other measures might be useful to get rodenticides out of our ecosystem, out of of the wild, out of our wild neighbors. Hopefully the legalization of cannabis in California will bring cannabis agriculture into the regulatory process. Maybe legalization will lead to the migration of cannabis agriculture out of remote wildlands and away from sensitive species such as the Pacific Fisher (Martes pennanti)and the Northern Spotted Owl, an icon of the struggle to preserve the Redwoods and the temperate rainforest to our north. But even if that happens, those measures do nothing to dilute the pollutant – to reduce the number of animals exposed to this poison.

Submission to regulatory review isn’t enough. The rat poison put out by a worker at a vineyard in Napa or Sonoma counties is likely legal. When vast swaths of our world are taken over by industrial agriculture, we cannot simply allow that land, its waters, its life, to become a sacrifice zone. If we are serious about diluting rat poison out of our environment, we need to stop producing it. We need to cease manufacture and sales of these poisons.

Update: In 2017, a leader in the effort to rid our shared world of these poisons, Raptors Are the Solution (RATS), worked with California Assembly member Richard Bloom, whose district (50) includes Santa Monica, Malibu, Topanga, West Los Angeles and Pacific Palisades, to bring a bill (AS-1687) forward that would complete the ban of SGARs in our state. It is currently stalled in the Assembly committee, Environmental Safety and Toxic Materials (ETSM). The bill as it is currently written would ban all use of SGARs except

 (1)  This section does not apply to the use of pesticides for agricultural activities, as defined in Section 564. … “agricultural activities” include activities conducted in any of the following locations:

(A) Warehouses used to store foods for human or animal consumption.
(B) Agricultural food production sites, including, but not limited to, slaughterhouses and canneries.
(C) Factories, breweries, wineries, or any other location where rodent or pest populations need to be controlled for food safety or agricultural purposes.

At the time of writing it is unknown if the bill will make it out of committee in time for this legislative year. If it does, we’ll keep you posted on actions that you can take to support its passage. For now, we are working to build strong support here on the North Coast, where we treasure our wildlands and wild neighbors, to eliminate these toxins from our shared world, our wild mother.

Want to help? One, contact your representative in the Assembly and let them know that you stand with our wild neighbors and want second generation anti-coagulant poisons fully banned. Here in the second district, you can send a message to our Assemblymember, Jim Wood. Two, help us build support here, in the heart of the Redwoods, where the Spotted Owls for too long has served as a bellwether of the costs our forests and forest communities pay for harmful human practices. You can become intimately involved with protecting our wild neighbors by volunteering at HWCC.

You can help us care for wild animals impacted by the toxins of a human built world, as well as advocate on behalf of our wild neighbors. Please donate today! Thank you!

Skunk’s Got White Stripes

Posted on by Monte Merrick

That don’t mean she’s the road to town
Skunk’s got white stripes
That don’t mean she’s the road to town
Just trying to find her lover
Everybody’s got to run her down

Every year the same thrilling tale that Nature has told since time immemorial ends in tragedy for many female Striped Skunks (Mephitis mephitis). In January here in Humboldt (as late as end of February for less temperate areas) female skunks begin to look for a mate. Their evenings are no longer spent watching over any remaining youngsters from the previous year. No longer content to saunter the night time world looking for food and whatever sparks her curiosity, now she is driven. The force of Spring renewal is powerful thing, sending her across fields and forests and very unfortunately, across roads too.

Three days ago, we admitted our first adult female skunk of 2018, who’d likely been hit by a car. Paralyzed and barely conscious, a quick, humane end was the only appropriate care. We rarely admit a skunk who’s been hit by a car simply because they rarely live through the impact. Instead, each January we see a sudden increase in skunks, dead and left to rot by the sides of our roads, from US 101 to the small two lane black tops that criss-cross the agricultural industry of the bottom lands. Samoa Blvd, from Arcata through Manila and south to North Jetty, on a these mid-winter days might have as many as four skunks freshly killed to be seen on the morning commute.

Accidents happen. Many of us can tell a story of hitting a bird, or a squirrel, or a raccoon without warning, with no chance to avoid the impact. It’s a terrible thing. The finality of it – and in the moment, the realized cost – this Swainson’s Thrush had crossed thousands of miles to be here to raise this year’s young, but no, instead, he’s lodged in the bumper of a car that had been speeding along with coffee creamer and a few other things that had been needed at the store. The casual slaughter of billions of wild animals each year by automobile is just another tragedy woven through the fabric of our daily lives.

In the last 12 months, how many Raccoons between Arcata and Manila, between Ferndale and Fernbridge, between Bayside and Freshwater, between Redding and Sacramento were struck and killed and left to bloat and decay by the side of the road, or worse, lure another animal, a Turkey Vulture perhaps, into the same trap. It’s a measure of how far below our concern these lives are, that we can tolerate their dead bodies lying on the margins of our thoroughfares decomposing where they were killed.

It must be the case that many animals are killed simply because we don’t see them, because we never see them. We don’t include them in our ideas about what might happen. We race through the dark as if the world was closed and nothing is real but the road, our headlights, our thoughts and the dark cavern of the sky. And the Road Runner startled by our engine’s roar dashes from the sage into our trajectory, smashed in the night by the predator who never eats – to be mourned if at all, only in the form of young who may have been orphaned to die, and the great sorrow of the Earth which is too large to hear – the Earth who reels in the blood of her freshest wounds and heals as she can from wounds long inflicted – strip mines, factory trawlers, pesticides sprayed across the plains, rivers choked…

There are so many wounds in the world today. Mudslides have killed at least 18 people in Santa Barbara County. In California alone, people in the last year have suffered one catastrophic calamity after another, in a world where greater disaster seems to always loom on the near horizon. It seems that there is little we can do about these wounds on this scale. But it’s simply not true.

Against these tragedies, we have a remedy. This remedy may not lower the temperature but will make the world where we are more beautiful, more just. Dr. King said that the moral arc of the universe bends toward justice, and we can do part of that bending right here, right now, in our tangible world and literally where the rubber meets the road. We can slow down and open our eyes. We can anticipate that we are not alone, free to tread where we will, to pay no regard to who is left broken or killed in our wake.We can find the joy in the nocturnal wild and search for their glowing eyes. We can stop teaching our sons violence as a form of play, violence as a right of passage – to respect the other lives, minds, hearts who they encounter. Far too many patients we’ve admitted were witnessed being run down intentionally, almost always a young man at the wheel. We can teach our sons now what it means to value the soul of another.

The world is made in moments and in each moment we can remember our first loyalty – to Earth and the wild. We can learn to undo our overly built confidence in the machinery of our times and re-align with our wild neighbors, our fellow travelers through this life on Earth, or kith, our kin; -our measured distance surmountable in a leap of recognition, not faith. We can give safe passage to this skunk here now, who is crossing the road, so that she might find who she needs, so that the world is refreshed, so that her young come to be.

A Barn Owl’s Broken Wing Heals

Posted on by Monte Merrick

Like most years, this winter Humboldt Wildlife Care Center has seen a significant increase in owls admitted for care that have been hit by a vehicle.

Very often the injuries to a Barn Owl (Tyto alba) after being hit by a car are too severe for successful treatment. There is simply no chance that the injury will heal, fully recovered. The bird will never be able to be returned to the wild and free life which is their birth right. It’s a tragic thing to admit an owl, in perfect body condition, at the prime of adulthood, but with a humerus no longer attached to the clavicle, ligaments torn, the shoulder joint torn apart, no longer able to use that wing forever.

Sometimes though, a Barn Owl gets a little bit of luck.

In mid-December, a Barn Owl was hit by car on US 101 in Arcata where the highway runs past the Mad River bottoms. Bottom land, such as we find all around Humboldt Bay, is perfect habitat for rodent-eating Barn Owls. Most of the Barn Owls we admit who’ve been hit by a car come to us from places where higher speed traffic cuts through the flat ranch lands of Arcata, Hydesville, Ferndale, and Loleta.

This Barn Owl, like many who are admitted after being hit by a car, suffered a wing fracture, rendering her unable to fly. Because of her size, at the upper end of the 400-550 gram weight range typical for her species, we assumed her to be female.

The fracture was in a tricky spot. Bird wings, forelimbs evolved for flight, have bones that are fairly analogous to our arms. Like all mammals and birds, Owls have a humerus that is connected to a clavicle (collar-bone), scapula (shoulder blade) and a coracoid (only birds have this bone, which provides support for the powerful downstroke of a beating wing and is not palpable). These bones come together in a mass of complex muscles and ligaments that form a shoulder that is capable of flight. Any of these bones can be fractured and recovery might still be possible, but dislocating bones from this joint, causing soft tissue trauma, ends in a patient who will never fly again. The functioning of this joint must be perfect or flight isn’t possible. Unfortunately, many birds suffer traumatic injuries to this joint when struck by vehicles or by collisions with buildings, usually a window.

Humerus fractures can be a problem because powerful flight muscles make it difficult to preserve alignment of the pieces of bone while they heal – usually this type of fracture requires surgery – a pin or some other kind of fixator must be used for the bone to heal properly. When presented with injuries like this, we often will send our patient south to Pacific Wildlife Care in Morro Bay, where Dr. Shannon Riggs, a highly skilled wild avian orthopedic surgeon who is also a BAX co-founder, works as Director of Animal Care.

After the humerus, just as with human anatomy, a radius and ulna make up the “forewing” after the elbow just as we have a forearm. Fractures to these bones run the range of easily healed with no problems, a complete return to function, all the way to broken beyond repair with no hope for recovery. The distance of the fracture from a joint, in this case the elbow or wrist, is an important consideration. Too close to a joint and a healed fracture might interfere with the range of motion, making flight impossible.

Beyond the wrist there are a couple of fused bones, the major and minor metacarpals, which are analogous to the bones between our fingers and our wrist. Next are three bones in sequence, vestigial digits after evolving for flight. The primary feathers, critical for controlled flight, attach to the wing along the digits. For mobility, lift, control and steering, the digits play a crucial role. At one time, fractures to the metacarpals and digits were not considered treatable. Fortunately, a splinting technique was developed that has changed that. It’s a splint that we use successfully several times a year.

This owl’s left wing, far beyond her wrist, was broken at the tip of her third digit. We stabilized the fracture with the splint that had been developed especially for this type of fracture. Using a piece of bandage material specifically for splints in conjunction with the rigid flight feathers to immobilize the fracture site while allowing freedom of movement to eat and perch, the splinted wing is held in place with a traditional wing wrap. We talked with Dr. Riggs about treatment, encouraged that fractured bone of the digit would heal much more readily than connective soft tissue.

The first examination also revealed that the owl was not able to stand fully, her left leg, no doubt the impact side, was much weaker than her right. Nothing broken was found in her leg, but swelling was present. Still, as injuries go, this owl was luckier than most in her situation. With splint applied, anti-inflammatory pain meds given, and some thawed out mice, her time in care began.

On a specially prepared perch that reduces captivity related problems such as pressure sores that can develop on the bottoms of a bird’s feet when spending much more time than usual standing and not flying. Perching and other housing choices are an important part of providing effective care. Knowing the natural history of many different wild species is critical if we are to treat patients appropriate to their needs.

In our large aviary (the Merry Maloney Raptor Housing)  after getting her splint removed, the Barn Owl exhibits very good flight! 

Captured for a routine exam, we are careful not to let these feet, both the tools of her trade and her only real defense against the likes of us, grab us. Tough enough to kill a large rodent, she’d cause some serious damage to a caregiver’s hand if we didn’t treat her talons with respect.

Silently swooping across the crepuscular sky, a Barn Owl is a swift and effective hunter. Even in an aviary, this owl’s flight was awe-inspiring.

The swelling in her left leg and her reluctance to use it improved immediately. Within a few days she was perching normally, able to hop around her housing, albeit with one wing tied behind her back.

An advantage that birds have over mammals is their much greater metabolism, which means that they heal much more quickly. Break a finger skiing and you’ll be in a splint for six weeks, while birds will heal in two! After 12 days, we partially removed the splint to check the progress of healing. The fracture site was nearly stable. We re-applied the splint and set her up for another check five days later, cautiously allowing a few more days than is normally required. Meanwhile, her attitude was becoming more fierce. After 17 days, the fracture site was was fully stable. We removed the splint and took her to an outdoor aviary. Immediately she took off n flight and flew around a corner and out of our view. We brought her some mice and left her alone. In a few days, after observing her flight in the aviary, we examined her one more time. In very good health, strong and fully recovered we released her back to bottom lands she hunts.

That moment when the patient realizes she is free and acts on it is a moment like no other.
Across the field…
And up toward the trees…


Putting as much distance between us as she can before stopping…

She alights on branches at the top of these tall alders and looks back toward us, toward her captors… does she know we helped? Who knows? It doesn’t matter. What matters is that she is free, using a second chance that was given her and this is the last of her looking back…
And then she leapt back into flight and was gone… returned to her wild freedom in the real world.

Wildlife rehabilitation is at least as old as human compassion, but as a profession it’s been less than 50 years that rehabilitators have been using trainings, regulations, and professional associations to improve available care for injured and orphaned wildlife all over the country. Innovations like the splint that gave this owl her second chance are made because of support generously donated. These innovations and improvements are passed on to other caregivers and are taught to the next generation of rehabilitators using the resources that your support provides. This Barn Owl is hunting the night-time world of the bottoms surrounding northern Humboldt Bay thanks to you making sure that we are here, doors open and ready.

Barn Owls are awesome and fortunately easily observed. But it’s their proximity to us, to the hazards of our modern world that are nothing but traps to animals evolved to the standards of Mother Earth, not industrial mechanized society  that are the greatest threat. It’s up to us to do what we can to slow down, be aware of the dangers we present to wild animals and modify our actions when we can. Co-existing with Barn Owls: it’s only natural.
