Wounded Western Grebes of 2014

When Western Grebes started coming in to Humboldt Wildlife Care Center in the middle of January, we were not sure what was causing their injuries. Large puncture wounds, crushed legs and wings… we surmised then and still have no better theory than conflicts with Sea lions when foraging. Over the course of the next few months, we admitted for care nearly 30 of these elegant and ferocious fish-eating birds.

Of these birds, however, only 2 were able to be fully rehabilitated and released. Most had injuries too severe to ever be able to heal well enough that they could thrive in the wild. This is without question one of the hardest parts of wildlife rehabilitation; – the repeated exposure to devastating injury.

Because aquatic birds need to be on water while in care this can make treating wounds below their waterline difficult. Only recent advances in aquatic bird wound management have allowed for more of these birds to survive their injuries and be returned to their lives. In the past it was assumed that the weeks required for deep, penetrating wounds to heal meant that birds who need to be on water were not good candidates for rehabilitation. Many birds with such wounds were euthanized for humane reasons.

With time and trial and error, rehabilitators have learned techniques that mitigate some of the negative outcomes of being kept off water as well as ways to successfully treat these wounds while the bird is housed on water. This requires skilled staff and purpose-built infrastructure.

So, while the number is low, two of the birds we treated recovered from their deep wounds and were recently released back to their free and wild lives. Thanks to your support we were able to provide the extensive, specialized care these birds require.

What am I in for? Well, let me tell you….

This Western Gull, entangled in fishing line and hooks at Trinidad Pier, was recently in our care (photos and story soon to come). You can help Bird Ally X/Humboldt Wildlife Care Center rescue and provide the necessary care for wild animals, like this gull, who encounter the modern world at its worst.

Gull Rescued Today in Trinidad

15 minutes before closing on 18 March the phone rang at Humboldt Wildlife Care Center. A young gull with a fish hook through his beak was begging for food at the Lighthouse Grill in Trinidad, about 15 miles north of Arcata.

When we arrived on the scene, we found exactly what the caller had described. With a little bit of patience and a little bit of available bait (by the way, the french fries from the Lighthouse Grill looked very good – hopefully we’ll get back for more when on less pressing business!) and with the appreciated assistance of the folks who made the initial call, we were able to net the young Glaucous-winged gull. We returned to the clinic and removed the nasty hook. There is no more rewarding work than succussfully removing a hook from a wild animal. (update: local ornithologist Rob Fowler has observed (see comment below) that this bird is most likely a Glaucous-winged x Western hybrid, so here’s a link to Western gulls too!)

The gull is in care now, treated with pain medication and offered healthy hook-free fish! The bird has an excellent prognosis.

Thanks to Julie and friend who made the call and stayed to help, to the onlookers who watched from a safe distance, to the older gull whose competition for the french fries made our soon-to-be-patient less wary of our net, and to everyone who supports our work and makes it possible for us to go on these rescues and provide the necessary care!

The Case of the Houda Point Screech-owl …

WESO in care FEB 14 - 28Found at Houda Point, barely able to move, cold, very dehydrated and thin, almost unable to stand, it took a few days before this Western Screech-owl became fully aware of his surroundings. By appearances, his prospects looked pretty bleak, but after repeated exposure to such patients in this shape, the miracle of fluids, warmth and nutrition when ready can seem commonplace. And one strong reason for his optimistic prognosis was his ability and willingness to eat mice soon after being admitted.

Because he is on the small end of the typical range for the weight and size of Western Screech-owls we surmise that he is male. While it is true for most birds of prey that females are significantly larger than males, sometimes by as much as a third, among screech-owls this difference is less pronounced, with females averaging 13% more body mass than males (1).

WESO in care FEB 14 - 01After ten days in care, the small owl’s condition had improved significantly. This is our first photo of him after being moved to an outdoors aviary.

Motor vehicles are the most common cause of injury for all the owls that we see. Last year at Humboldt Wildlife Care Center we treated 50 owls of various species. We know that 26 of these owls had been struck by a vehicle. 24 of the owls we treated were Western Screech-owls. Of these 24, 14 had been hit by a car. Due to the typical severity of injuries car strikes cause, only 5 survived to be released.

While an owl might fly in front of your moving car anywhere, it is important to remember that these nocturnal hunters use the edges of roads to find prey. Maybe before we destroy the world we’ll realize that a good neighbor puts lives before speed. Etiquette and courtesy: why not teach these things first about living in nature?

WESO in care FEB 14 - 41With his feet wrapped in cohesive bandage, Dr. Lisa Bartlett of Arcata Animal Hospital examines the owl’s legs while BAX rehabilitation assistant and board member Lucinda Adamson handles for her.

WESO in care FEB 14 - 09After 3 weeks in care, the owl was visibly more alert and energetic

This Screech-owl, however was not likely to have been hit by a car. After a few days in care, with varying ability to stand, his legs began to swell. Both legs had multiple small puncture wounds. With antibiotics and anti-inflammatory drugs added to his daily care, he soon improved.

While we’ll never know for sure what caused his injury, we speculate that it was a conflict with another predator, perhaps a feral or free-roaming cat or even another Screech-owl.

No matter the cause, this owl’s injuries healed quickly. A lingering problem with his left hock (analogous to a human ankle) where a puncture from claw or talon was causing apparent pain and swelling took a few weeks and a couple of trips to the veterinarian. Twice we needed radiographs to confirm that the joint was healing and this small owl would be able to carry his dinner (primarily small rodents such as mice and voles) back to his roost or nest. Carrying mice back to his partner is an important part of screech-owl mating. When nesting, the male screech-owl also shares the duties of hunting for the nestlings once the chicks have left the egg(2).

WESO in care FEB 14 - 36Our small patient recovers in our newest aviary, built in 2013.

Because a wild animal needs to be in top physical condition to thrive, our concerns regarding the use of his leg required a cautious approach to his release. Besides physical examination and radiographs to make sure that his bones were healthy, we offered live prey to determine that the owl was capable of providing for himself after release.

WESO in care FEB 14 - 25Evading capture! While we aren’t trying to cause our patient’s stress, it is nice to see his restored vigor and agility.

WESO in care FEB 14 - 26A remarkable feature of owls in flight: near-total silence as they rush past your head!

After another couple of weeks in care, we were sure he was ready. Two BAX/HWCC interns and Kim Hettler-Coleman, our volunteer coordinator, took the owl back to Houda Point, back where he’d been found. After coming back from the release Kim reports, “As he sat in the hollowed out part of the tree, disappearing into his surroundings, all was well, in the owl’s world and mine. Freedom never looked so good … in camouflage!”

Did Your Pot Kill A Hawk?

Last Saturday, the 22nd of February, the Environmental Protection Information Center (EPIC) and Environmentally Sound Productions put on a benefit concert to raise money for a campaign to get rat poisons out of marijuana production. Bird Ally X /Humboldt Wildlife Care Center supports this effort wholeheartedly. So we drove down to set up an information table at the show and spoke briefly regarding the impact of rat poisons on local wild animals, including the orphans that result when parents are killed! While we don’t endorse the idea of using any poison, second generation anti-coagulants (such as D-Con, etc.) are particularly nasty. We’ll have more on rat poisons soon.

California Red-sided Garter Snake in Care

Garter Snake Feb '14 - 14A student at Humboldt State University found a snake on the sidewalk near his dorm last Saturday that didn’t move away from him as he approached. Of course a wild animal in good health would have fled. He didn’t know the species but he knew something was the matter. He called our clinic and one of our dedicated volunteers drove up to the campus to pick up the snake. While many of us are very familiar with Common Garter snakes, greenish with yellow stripes, this snake turned out to be a local subspecies, the California Red-sided Garter Snake, and his appearance is quite lovely!

Garter Snake Feb '14 - 06Two-thirds down his length, the snake suffered a small laceration. Soon we’ll have radiographs that will determine the extent of any skeletal damage.

For now the snake is comfortably healing. While no wild patient is out of the woods until they are out of captivity, this snake enjoys a good prognosis.

Hooked by Unattended Line, Western Gull Heals and is Released

At a quarter to five a couple of Sundays ago, just as we were completing the day’s tasks and getting ready to leave the clinic, the phone rang. An employee at Pacific Seafood, a fish processing facility on the Eureka waterfront, had spotted a gull nearby who was tied to some fishing line. We quickly fed the last couple of patients and headed out to take a look.

Fish hooks and fishing line cause numerous wildlife injuries. The toll fishing gear takes on marine birds, reptiles, and mammals (not to mention the targeted species!) numbers in the thousands along the California coast alone each year. (see study here) According to the Humane Society of the United States (link here) over a million marine animals are killed each year by “longline” fishing at sea.

(a collection of hooks and other items removed from patients at Humboldt Wildlife Care Center)

Hook and line injuries are commonplace for all wildlife rehabilitators, especially in locations where wildlife and people co-exist in large numbers – San Francisco, Monterey Bay, Los Angeles…

When we arrived on the scene, the fellow who called was standing a few yards from an adult Western Gull (link), who was trapped on the wharf, a hook in his (or her) neck attached to a line tied to the railing. Someone had been fishing and left his rig in the water. The gull had tried to eat the bait and gotten hooked.

We netted the gull and wrapped her (or him) in a towel. We made a quick examination to see if the hook could be immediately removed. Sometimes, with a quick snip of the barbed end, the hook comes out, and the small wound is fine to heal on its own – the bird can be released right away. In this case, however, the hook was small and difficult to see in the fading late afternoon light. For safety’s sake, we brought the gull back to our Bayside clinic.

WEGU release story 19 Feb - 1

DSC_0869Under the examination light, the small hook was easy to see. After removing it, we found a deep pocket of pus inside the gull’s mouth – an old infected injury. The bird’s feet also had early stage pressure sores caused by a life spent on concrete.

There is no getting around the fact that in a very short time modern industrial civilization has re-shaped the world that we share with other animals, other life. Derelict fishing gear, automobiles, ocean pollution, climate disruption, domestic animals, glass windows, resource extraction, – the list is long and each threat is new. All the marine birds we see today have existed as they are for at least 20 million years (Gaston 2004). Each of this gull’s injuries was the result of civilization’s altered environment.

The infection in our patient’s mouth required a course of antibiotics. We gave the first dose and set up safe housing for the night, fed some fish that had no sharp surprises, turned off the lights and headed home.

WEGU release story 19 Feb - 2The next morning we moved the bird to our aviary built especially for gulls, pelicans, and cormorants – all marine birds who spend time in and out of water. With a large pool, an artificial rock wall, high perches and a substrate (all surfaces that the birds might perch on) intended to relieve the constant pressure on their delicate feet, this aviary is a key part of our rehabilitation program. When treating wild animals, patient housing plays a leading role in their recovery.

Over the course of the next ten days the gull’s condition swiftly improved. The deep wound inside his mouth healed, the punctures from the hook healed. Her (or his) feet had improved too.

Last Tuesday the gull was released at North Jetty. Once out of the box, the bird took time to preen – which is how birds maintain their feather condition. Besides allowing flight, the feathers of all birds protect them from the elements. For aquatic birds this is particularly necessary – as warm blooded animals who live in the cold North Pacific need an impeccable array of feathers simply to surivive. Once satisfied that all was well, s/he launched from the rocks out over the inlet to Humboldt Bay and was gone.

There are many things you can do to help prevent this kind of injury to wild animals:

  • Most importantly, if you fish, mind your gear. Try not to leave anything in the environment. Line, hooks, weights, all of these can produce fatal and torturous wounds.
  • If you find derelict gear in the environment, remove it! Every hook removed from the docks, beaches and river banks is a hook we won’t ever have to remove from a bird’s mouth.
  • Pass this information along!
  • Support wildlife rehabilitation. Our ability to do this work depends directly on community support. BAX/HWCC is not funded by the county, state or federal governments. Your contribution makes our work possible. Thank you!
