Located in the north-east corner of Massachusetts, Plum Island is an excellent birding hotspot where you can find a great variety of birds, especially in the Spring and Summer.

The best birding is on the southern end of the island in the Parker River National Wildlife Refuge. This 4,662-acre wildlife sanctuary offers many habitats that attract a wide variety of different birds.

The Hellcat Dike Trail takes you through several different habitats. The trail is excellent and includes a raised boardwalk that meanders through the forest.
