Follow the Raptor Migration

A birder peers through a spotting scope.

Hawk Watch Coordinator Phil Brown uses a spotting scope to get a better view of passing birds.

Biologists regularly record up to 15 different raptor species from platform at the Pack Monadnock Raptor Observatory. From mid-September through mid-October, significant daily and seasonal flights of Broad-winged Hawks, Sharp-shinned Hawks, Northern Goshawks, Peregrine Falcons, Ospreys, and Bald Eagles are possible. Mid-October through mid-November often brings Golden Eagles and Northern Goshawks.

During the migration season, detailed reports — including hourly raptor count and weather data, non-raptor observations, special notes, season totals, and next-day forecasts — are posted at the end of each day on hawkcount.org, an online database managed by the Hawk Migration Association of North America (HMANA). Historic migration data are also available via hawkcount.org.
