As a former undergraduate researcher and now postgraduate research technician with the Cornell Wildlife Health Lab, I have mostly worked on a study of environmental contaminants in hunter-harvested waterfowl....

While the recent population recovery of bald eagles in New York State is a conservation success, evidence from necropsies suggest that ingested lead from ammunition fragments is causing morbidity and mortality to wild eagles.

Mange is a parasitic skin disease found in free-ranging wildlife populations and has been increasingly reported in black bears over the last decade in New York State. This paper led by Cornell researchers describes the geographic, seasonal, and demographic factors associated with mange in NYS black bears.

The New York State Wildlife Health Program is a key partnership between Cornell and the New York State Department of Environmental Conservation. The program coordinates responses when disease strikes New York’s wild animals and it helps prevent outbreaks, in domestic animals and people too, by translating data into policy.

Bald eagles are considered a recovery success in the U.S. after rebounding from near extirpation due to widespread use of DDT. Although abundances of bald eagles have increased since DDT was banned, other contaminants have remained in the environment with unknown influence on eagle population trends.
