Important Bird Areas

Butler Sanctuary

New York

A ridge and swale area in a heavily developed area of Westchester
County. The two ridges that compose the bulk of the sanctuary run in a
north-south direction and are 700 or more feet in elevation. The hawk
watch takes place on an observation platform located at the highest
point (above 775') on the easternmost ridge. From the hawk watch,
Long Island Sound can be seen. This site is owned by The Nature
Conservancy.

Conservation Issues

Bedford Audubon Society has sponsored a hawk watch, which was
not conducted in 2003 and 2004, but is expected to resume in 2005.
Monitoring of hawks should continue. Bird monitoring in the
surrounding forests is recommended as well.
