"Birds of Casco Bay" with Seacoast Tours Trip Report

Our first ever “Birds of Casco Bay” in partnership with Freeport’s own Seacoast Tours featured a rewarding escape from the heat on a sultry early summer day on June 6th, 2021. With temperatures rapidly rising to near 90-degrees, we were sure glad to be offshore enjoying a light but refreshing breeze.

We motored around several of the islands between Freeport and Harpswell, checking ledges and outer islands for various bird- and wildlife. Harbor Seals were numerous, and we spotted a couple of Harbor Porpoise. All the expected local breeding birds were seen well, including numerous Ospreys, two Bald Eagles at their nests, lots of Common Eiders, Herring Gulls, Great Black-backed Gulls, and Double-crested Cormorants. Common Terns were, well, common, and we spotted several Great Blue Herons, two oversummering Common Loons, and heard and saw several Song Sparrows singing from sparsely vegetated, treeless islands.
