PORTLAND, Ore. (KOIN) — A bald eagle that was found on the side of the road in Mt. Tabor Park on Feb. 18 has died after an Oregon State Police trooper attempted to rescue the sickly animal.

Oregon State Police Capt. Kyle Kennedy told KOIN 6 News the eagle likely died as a result of avian flu. The Oregon Department of Fish and Wildlife states that a highly pathogenic strain of bird flu that was first detected in North America in 2021, continues to cause sickness and death in wild birds, including geese, shorebirds, raptors and vultures...

Klamath Basin wildlife refuges battle suspected botulism and bird flu outbreak
August 17, 2024
Excerpts:
A combination of botulism and bird flu has led to estimates of thousands of birds dying in the Klamath Basin National Wildlife Refuge Complex this summer.

Birds are dying at the Tule Lake National Wildlife Refuge in far Northern California. Last week, refuge staff deployed in a boat and collected 500 dead birds from Sump 1A, the largest water body in the Tule Lake Refuge.

John Vradenburg, supervisory biologist at the Klamath Basin National Wildlife Refuge Complex, suspects they’re dealing with a dual outbreak of botulism and highly pathogenic avian influenza, which was discovered in the refuges earlier this summer.
​-snip-
A complex of six wildlife refuges spanning the Oregon-California border, the Klamath Basin National Wildlife Refuge Complex serves as vital feeding and breeding grounds for tens of thousands of birds that use the Pacific Flyway to migrate.
-snip-
“Compared to what we can tell from historic records, this is the highest and most diverse waterbird population we’ve had on Tule Lake in three or four decades,” says Vradenburg. He estimates there are about 30,000 nesting grebes on the large water body known as Sump 1A, and 250,000 molting birds and up to 60,000 ducklings on Sump 1A and Sump 1B combined.​
-snip-
But after the last water releases from Upper Klamath Lake in May, the wetlands in the refuges began to warm and dry out, heightening the risk for an outbreak of avian botulism.
-snip-
On July 12, KWUA sent the Bureau of Reclamation a letter, urging the agency to take action to avoid a disease outbreak on the refuges, and to increase water allocations to irrigators to save this year’s crop harvests.
Around that same time, refuge staff started spotting dead and dying eared grebes. All of the samples they collected tested positive for highly pathogenic avian influenza.
​-snip-
The combination of bird carcasses, drying wetlands, and warm water created a “perfect storm” of conditions for botulism, says Vradenburg.​
-snip-
Avian flu complicates outbreak response
For the last two weeks, refuge staff have been surveying the wetlands and collecting dead birds. Vradenburg estimates at least 5,000 have died so far.
The likely presence of highly pathogenic avian influenza is complicating how they respond to the crisis. Unfortunately, this means staff can’t set up a rehab hospital to treat birds sickened with botulism, as they have in the past, because they can’t risk people coming into contact with the bird flu virus in a confined area.​

Samples have been sent to the U.S. Geological Survey’s National Wildlife Health Center in Madison, Wisconsin, for analysis. At this time, all of the refuges are still open to the public.​​
