With its location along the St. Croix River in downeast Maine, Saint Croix Island International Historic Site offers a chance to see many different bird species.

Habitats
The site includes a short woodland trail situated along a narrow peninsula of mixed deciduous and evergreen trees, flanked by two small protected coves. In one cove, a perched culvert draining upland fresh water creates a waterfall effect that lures bald eagles in early morning. An apple orchard adjacent to the second cove creates another habitat for a variety of birds and wildlife. At the end of the trail, an interpretive shelter overlooks Saint Croix Island and the St. Croix River estuary, where brackish water and tides up to 25 feet invite a variety of birds year round. Mud flats form at low tide.
