Spring Migration

Hawk Mountain has monitored the spring raptor migration intermittantly since the
1960s using several different observation points. Since 2000 the count has been conducted daily at North Lookout by Conservation Science interns between April 1 and May 15. This count is designed to capture the second half of spring migration and is used in part as a way of training interns in migration count techniques. Experienced volunteers and staff assist with the training during early April and volunteers also count some days during March.

Annual counts for this 45-day period average 1,063 raptors total with usual one-day peak counts of more than 100 birds seen during late April. Spring flights are best with southerly winds and cloud cover.
