Beak deformities in Northwestern Crows: Evidence of a multispecies epizootic Beak deformities in Northwestern Crows: Evidence of a multispecies epizootic
Beak abnormalities are rare among adult birds and, typically, are not widespread in a given population, within a region, or across multiple species. A high concentration of beak deformities was recently documented in Black-capped Chickadees (Poecile atricapillus) and other resident avian species in Alaska. We describe a parallel condition in Northwestern Crows (Corvus caurinus) that...

Epizootic of beak deformities among wild birds in Alaska: An emerging disease in North America? Epizootic of beak deformities among wild birds in Alaska: An emerging disease in North America?
The sudden appearance of a large cluster of animals with gross abnormalities may signal a significant change in an ecosystem. We describe an unusual concentration of beak deformities that appear to have arisen rapidly within Alaska and now extend southward along the Pacific Coast. In Alaska we have documented 2,160 Black-capped Chickadees (Poecile atricapillus) and 435 individuals of 29...

Alaskan birds at risk: Widespread beak deformities in resident species Alaskan birds at risk: Widespread beak deformities in resident species
The team creeps silently across a well-tended lawn, eyes drawn to a small wooden box perched several meters up a lone birch tree. The first biologist is armed with a broom in one hand and a bug net in the other. Her partner wields a lunchbox-sized plastic case and a tree-climbing ladder that looks like an oversized radio antenna. A neighbor peers out her window from across the street to...
