Corvus brachyrhynchos

The American crow is one of the few species which, in spite constant efforts by farmers (from the first colonists) to eliminate them have actually increased in numbers.  Crows are very intelligent birds, and have adapted well to urban life.  This web site is the outgrowth of a project which I started in 1980, when I discovered that many of my students (8th grade) were certain that a crows bill, eyes, and feet were yellow!   And that when dozens of crows were on the school fields every day.

In the early 2000's the crow population crashed, due to the West Nile virus.  By 2010 their numbers are slowly increasing again.
