Passagassawakeag River Professional Review and Guide
"Birding could not be easier—a brand-new footbridge across the Passagassawakeag River opened to the public in 2006. The bridge allows birders to scan upriver and also gives a good view of Belfast Harbor. Boaters can launch at the Belfast Public Landing (for a fee) and head up the river, following the winding channel. Navigable water ends about 2 miles from town. A power line crosses the river at a narrow point, and in summer Double-crested Cormorant sit on the line.
The Passagassawakeag River, or “Passy,” has long been noted as a place to visit in winter to watch for Barrow’s Goldeneye, a key species here. Additionally, expect to see Common Goldeneye, American Black Duck, and Common Eider. This site hosts a mixed bag of gulls, including Glaucous, Iceland, and Bonaparte’s. Common Tern are here in good numbers, too. Bald Eagle and Osprey often cruise the river, and a high-tension powerline near the river’s head of tide holds an Osprey nest."
