194. Chestnut Ridge Hawk Watch, Mt. Kisco, New York

A hawk watch north of New York City that regularly tallies the highest counts of any watch site in New York State.

In most years, observers at Chestnut Ridge record the highest raptor totals of any autumn watch in New York State. The site’s biggest attraction is the sometimes-spectacular Broad-winged Hawk migration in mid- to late September. Chestnut Ridge also gets good numbers of Sharp-shinned and Cooper’s Hawks a little later in the season, Red-shouldered Hawks in late October and early November, and Golden Eagles and goshawks from late October through November.

As I walk up the trail leading to the watch platform in the morning, I often run into fall warblers and other migrant passerines. Seats on the wooden platform provide an expansive easterly view toward Connecticut and Long Island Sound.

Standardized hawk counts have taken place here since 1979. The Bedford Audubon Society hires a hawk counter and an intern every year, and the watch is manned daily from late August to late November, weather permitting.

Raptors are the stars, of course, but Chestnut Ridge is also a great spot to watch songbirds in the morning, nighthawks in the evening, and migrating hummingbirds and monarch butterflies. — Tait Johansson

Tait Johansson is a naturalist at the Bedford Audubon Society and the coordinator of the Chestnut Ridge Hawk Watch. He was the official counter in 2000 and 2001.
