Bald Eagles in New Hampshire: where to see them and how to identify them

Where in New Hampshire are bald eagles most likely seen?

Concentrate along major rivers and lakes with open water during winter. The Merrimack River from Franklin to Concord, the Contoocook River, and Lake Winnipesaukee consistently hold eagles. I've had the best luck below the Sewalls Falls Dam in Concord and along the Squam Lake shoreline in early morning.

What time of year and time of day is best for spotting them?

December through March is prime time when ice pushes eagles to open flows and unfrozen lakes. Arrive by sunrise or stay until late afternoon; eagles are most active feeding at those times. Midday can be slow as they often perch and digest high in tall pines.

How do you identify a bald eagle in the field?

Adult bald eagles are unmistakable with their pure white head and tail and dark brown body. Juveniles are all dark with mottled white wing linings; they take four to five years to get the adult plumage. Compare size: eagles are huge, with a 7-foot wingspan, and fly with flat wings held straight out, unlike the V of a turkey vulture or the jizz of an osprey.

What kind of habitat do bald eagles prefer?

They need large trees for roosting and nesting near abundant fish. In New Hampshire, look for eagles along forested riverbanks, lake shores, and around dams where fish congregate. Dead snags with sturdy branches are favorite perches. I've watched eagles return to the same white pines along the Merrimack for years.

Are there any recommended viewing spots in New Hampshire?

The Audubon Society runs winter eagle trips on the Merrimack. Personal favorites: the pedestrian bridge at Sewalls Falls, the public boat launch at Lakeport, and the Squam Lakes Natural Science Center area. For more state-wide info, visit our New Hampshire wildlife page.
