Last American Wigeons from Klamath Basin Botulism Outbreak Released!

As we described in past posts, in the middle of August, staff at the Lower Klamath Wildlife Refuge, which straddles the state line between California and Oregon, discovered an outbreak of avian botulism that was killing ducks by the hundreds.  Managed by BAX co-directors January Bill and Marie Travers, and working with Refuge staff, our response successfully treated and released 297 ducks and shorebirds.  The last three ducks in care, each American Wigeons (Mareca americana) were transferred to Humboldt Wildlife Care Center because they weren’t ready for release  and could take advantage of our seabird and diving duck pools.

[Our goal of $10,000 by October 31 has not been met! In fact, we are far from it. Our resources are emptied after a busy baby season. Thank you to everyone who has contributed during this drive. We need your help. If you want to donate now, click here ]

After a week in our pool, each duck was ready for freedom. Fortunately, at the nearby Arcata Marsh, there are hundreds of overwintering Wigeons with plentiful food available. It’s possible these three wigeons would have made it to Humboldt Bay this Winter anyway.

In any case, after a brush with death by botulism, a lifesaving trip through our rapidly manifested “Duck Hospital” set up near the Lava Beds, followed by some time spent in our pools, gaining weight, improving feather condition, restoring red blood cells, and gaining strength, these Wigeons returned to their wild and free lives, healthy and ready for a winter of easier times.

The first American Wigeon was released several days before the other two. She made short work out of getting hid in the vegetation of the pond.

Thick with duckweed and other food, the Arcata Marsh proved her a soft landing at release.

About thirty feet away scores of wintering Wigeons make use of the Marsh as well.

Providing a hiding place for our patients lowers their captivity-caused stress and helps them focus on recovering. This female Wigeon lurks behind her blind, hoping to avoid capture.

Of course, when that capture is intended for healing and release, we take liberties that ordinarily would be unethical, handling and housing without consent.

Rudimentary blood analysis will provide data that confirms our impression that she is ready for release. Here a small sample is collected to be given a ride in the centrifuge so that we can measure percentage of red blood cells – as the carriers of oxygen through the body, they are critical for all aspects of life. We can also get indications of possible unseen infections and other maladies which can affect total protein solids in the plasma that is separated from the red blood cells, which we also measure.

Here we examine a previously swollen foot to see if the problem has resolved well enough that she will be fine in her natural environment. The answer was yes!

About a week after being transferred from Tulelake, the two last Wigeons were released in to the same pond as the first Wigeon. Each bird is her own person and does what she wants. The first Wigeon we released dove for cover in the vegetation, this one flew as quickly away as she could.

The third Wigeon swam away, accompanied by a Mallard who we’d also treated at HWCC and released that day.

The Arcata Marsh is one of the gems of our neck of the woods. Knowing that these birds are making there way with quality food available and in the freely-chosen company of their kind after their long ordeal is very relieving. The habitat of our home is not just for show. It’s the actual living place of our wild neighbors. It’s our home too. Our wild neighbors aren’t just like some new family who recently moved here from Atlanta but who will soon be moving to Seattle. They are our kin. We have the same needs. Our shared home is worth loving and respecting.

HWCC volunteer Katharine (l) and 2018 Intern Desiree Vang (r) are displaying the typical expressions worn by members of their species who are experiencing fulfilling joy. Warm smiles. Successful releases of our wild patients are like that.


The challenge of 2018, so far the busiest year in HWCC history, has been at times a joy and at other times deeply stressful. The avian botulism outbreak in the Lower Klamath Basin, a region that is just on the other side of Shasta, just up the Klamath River, was difficult but also very fulfilling – launching a successful emergency wildlife response is a very gratifying experience. The privilege of doing our work is something no wildlife rehabilitator takes for granted. So far in 2018 we’ve met every challenge but the financial one. We need your help. In the midst of these ever greater demands, our resources aren’t merely not growing to meet them, but are shrinking. The world is full of demands for support, pleas for generosity. The world is in upheaval right now. We know, we work on the front lines of the devastation. And the only thing that keeps us here, keeps our pools functioning, keeps our facility’s rent paid, keeps our phone on, keeps our care improving, keeps our reach expanding, is you. Please donate today. We need your help. Thank you!
