Where To Spot Maine’s Water Birds

Aside from all along the Maine coast (especially great for spotting sea ducks) the following places are great for spotting wading birds and other water birds:

Acadia National Park, Mount Desert Island: Nestled on the coast, this national park provides a home for a variety of water birds, including the Common Loon, various ducks, and the American Black Duck, the green winged teal and the female and male wood duck.

Rachel Carson National Wildlife Refuge, York County: Covering 50 miles of coastline, this refuge is a haven for water birds, including the American Bittern, the Least Bittern, and the Green Heron.

Moosehorn National Wildlife Refuge, Baring and Edmunds: As one of the northernmost National Wildlife Refuges, it offers sightings of the Common Goldeneye, the Hooded Merganser, and other species in its marshes, streams, and ponds.

Sunkhaze Meadows National Wildlife Refuge, Penobscot County: With a mix of wetland habitats, it is an ideal location to see species such as the American Black Duck, the Ring-necked Duck, and the Canada Goose.

Eastern Egg Rock, Muscongus Bay: Home to the Project Puffin restoration project, this tiny island attracts Atlantic Puffins, Common Terns, and Roseate Terns during breeding season.

Other spots include Machias Seal Island, you’ll commonly encounter on Machias Seal Island include species like puffins, razorbills, and terns, which have adaptations more suited to a life spent in or near the sea. Unlike ducks, these seabirds are equipped to dive deep into the water to catch their prey.

The Fish and Wildlife Service in Southern Maine advises against feeding Canada Geese for several reasons.

First, providing food can lead to an artificial increase in the population of these geese, which can cause overgrazing and degrade natural habitats. This can disrupt the balance of local ecosystems and have negative impacts on other wildlife.

Second, feeding can result in the geese becoming habituated to humans. This can lead to them becoming aggressive or causing nuisances in public spaces such as parks or residential areas.
