On a visit to Ithaca, New York, I saw a crow with large, red tags on each shoulder. Is this one of your projects?

Yes—those are what we call “Kevin’s crows.” Lab scientist Dr. Kevin McGowan has been following individual crows in our area for decades. His research has taught us many things about these common and widespread birds, including giving us insight into the epidemic of West Nile Virus and learning about ways crows cooperate. Kevin works in our education department, and he maintains his own site all about his crow project.
