Fall Raptor Migration at Greenbrook 2005 |
|
|
Greenbrook’s position atop the cliffs of the Palisades, overlooking the Hudson River, provides visitors to the sanctuary with an excellent view of the annual fall hawk migration. Although not an official, full time watch, staff and members spend many hours observing the raptors passing along this portion of the Atlantic Flyway. The annual fall hawk watch programs at Arboretum Point—a vista 350 feet above the river—have become very popular, enjoyable events for both the staff and members. As always, visitors are encouraged to post their observations on the “Wildlife Sightings” bulletin board in the parking area. The table below is a tabulation of these sightings and staff observations. Scroll down to see raptor abbreviation key.
