BRIDGTON — The arrival of mid-September’s cooler weather coincides with New England’s largest hawk migration of the year. On Sept. 30, from 11 a.m. to 2 p.m., Loon Echo Land Trust Biologist Paul Miller brings his enthusiasm for the southern hawk migration to Hacker’s Hill Preserve in Casco for a Hawk Migration Watch Program.

Numerous species of hawks begin their seasonal migration around this time and under ideal conditions birders have seen over one thousand in a day. Optimal conditions for migrating hawks are a northwest breeze with clear skies. In past years many varieties of hawks have been observed along with bald eagles and osprey. This program is free and open to the public as part of the Great Maine Outdoor Weekend. Bring a lawn chair, binoculars, water and snacks.

Parking is available by driving to the top of the road into Hacker’s Hill Preserve on Quaker Ridge Road in Casco, approximately one mile from the Route 11 intersection and four miles from the Route 302 intersection. Those attending should park in the event parking area to the right of the summit.
