There are several different birding boat tours, whale watches, and pelagic trips that leave from Bar Harbor and other Maine ports. For pelagic trips, familiarize yourself with eBird's pelagic protocol and use the appropriate personal locations or eBird hotspots

The eBird pelagic protocol applies to checklists that are made farther than two miles offshore on oceans, seas, or large lakes. Choose the Pelagic Protocol option from the ‘Other’ menu of Observation Types. Please note that we still have much to learn about seabird distribution, so we encourage you to add photos and notes to document your sightings on your checklists! 

If you’re moving: Count for up to 60 minutes on each checklist; stopping at the 1-hour mark. Record the distance traveled (ideally with eBird Mobile Tracks), adjust the distance estimate for backtracking as you would a traveling checklist, and choose a location on the map for where you started that checklist period. Repeat this process throughout the trip until you return to within two miles of shore.

If you’re anchored: Keep a checklist for as long as you’re anchored, and then follow the above instructions once you start to move again.

Great and Sooty Shearwaters often dominate the ocean during the second half of summer. Wilson's Storm-petrels can be abundant. Some of the world's biggest colonies of Leach's Storm-petrels also nest along the Maine coast, but their nocturnal habits make them difficult to find. In August, after breeding, they are sometimes seen in daylight from the whale-watch boats, especially off Acadia National Park. Bar Harbor Whale Watch is outstanding for pelagic species during its whale trips. Northern Gannets are frequent sights. Red and Red-necked Phalaropes gather offshore by the thousands later in summer.

A few Northern Fulmars are seen, and their numbers increase late in the season. Parasitic and Pomarine Jaegers are regularly seen from whale-watch boats, and a Long-tailed Jaeger is spotted in most years. Great and South Polar Skuas are seen sporadically and seem to be on the increase. All of the local alcid species are possible, especially in post-breeding dispersal.

Currently, the number of boat tours for pelagic birding in Maine is increasing. Maine Audubon offers the largest tour in autumn. Its annual trip on the Bar Harbor Whale Watch boats from Bar Harbor attracts birders from all over the world. In 2007, Maine Audubon began organizing additional trips to Matinicus Rock.

Northern Gannets, Black-legged Kittiwakes, Great and Sooty Shearwaters, Razorbills, and Common Murres are often seen from the Grand Manan ferry.
