Bird List

With a record of 338 bird species encountered, Acadia National Park is considered one of the premier bird-watching areas in the country. Twenty-three species of warblers alone have been recorded as breeding in the park! For a checklist of the birds in the area, click here.



HawkWatch

Every year, strong northerly winds push thousands of raptors from Maine and Canada south along the eastern coastline as they migrate to warmer areas for the winter. With its wide-open views and tallest vantage point on the eastern coast, Acadia's HawkWatch location on Cadillac Mountain often provides visitors with a close look at the soaring raptors. Each year, program participants see large numbers of sharp-shinned hawks and American kestrels.

Discover what's happening this season at the HawkWatch in the weekly update, Riding the Winds, and view the recent daily counts for each species at Cadillac Mountain. To help you identify flying raptors, click here for a silhouette guide.

With diverse habitats from ocean shoreline to the granite tops of mountains, Acadia National Park contains many different types of insects. Just how many, we're not sure.

From 1928 to 1944, William H. Procter studied the invertebrates in the park. Today, park staff protect his collection as part of the curatorial program.

The park continues to learn about its insect species through the BioBlitz series, where biologists and naturalists conduct a rapid assessment of a specific group of invertebrates over a 24-hour period. These BioBlitzes document species occurrence, provide estimates of species richness, and identify rare and unique species.
