The Maine coast is home to dozens of bird species that thrive along rocky shorelines, offshore islands, and open ocean waters. Visitors commonly see Atlantic puffins, terns, gulls, cormorants, eiders, razorbills, and northern gannets. Many of these birds spend most of their lives at sea and return to Maine’s coastal islands each summer to nest and raise chicks.

For bird lovers visiting Boothbay Harbor, the best way to see many of these species is from the water. Wildlife cruises travel to offshore islands and feeding grounds where seabirds gather in large numbers.

Why Maine’s Coast Is a Birding Hotspot

The Maine coast supports a wide variety of bird species because of its unique geography. Thousands of rocky islands, nutrient rich ocean waters, and protected nesting areas provide ideal habitat for seabirds and migratory birds.

These conditions attract birds that feed on small fish and marine life found in the Gulf of Maine.

Common reasons birds thrive along the Maine coast include:

• Hundreds of offshore islands for nesting

• Abundant fish and marine food sources

• Protected wildlife refuges

• Seasonal migration routes along the Atlantic Flyway

Boat tours often provide the best viewing opportunities because many seabirds stay far from shore. One popular way to explore these bird habitats is aboard the Puffin & Scenic Cruise with Cap’n Fish’s Cruises, which travels to offshore islands where puffins and other seabirds nest.

Atlantic Puffins: Maine’s Most Famous Coastal Bird

Atlantic puffins are the most recognizable bird along the Maine coast. These colorful seabirds nest on a small number of protected islands and return each spring to raise their chicks.

Puffins are sometimes called the “clown of the sea” because of their bright orange beaks and expressive faces.

Key facts about Atlantic puffins:

• Puffins spend most of their lives at sea

• They return to Maine islands between May and August to nest

• They dig burrows underground to protect their eggs

• Both parents help feed the chick

Eastern Egg Rock near Boothbay Harbor is one of the best known puffin nesting areas in Maine. Visitors hoping to see puffins often join the Puffin & Scenic Cruise or the Whale & Puffin Combo Cruise, which travel to offshore islands where these birds gather.

FAQ: Where can you see puffins in Maine?

Atlantic puffins nest on several protected islands along the Maine coast. Eastern Egg Rock near Boothbay Harbor is one of the best locations to observe puffins during the summer nesting season.

Common Seabirds Found Along the Maine Coast

The Maine coast hosts many seabirds beyond puffins. These species are commonly spotted around harbors, islands, and offshore feeding areas.

Terns

Terns are graceful seabirds known for their sharp wings and dramatic dives into the water while hunting fish.

Common species include:

• Common tern

• Arctic tern

• Roseate tern

These birds often nest in large colonies on protected coastal islands.

Gulls

Gulls are among the most familiar birds along the Maine shoreline. Two species are especially common.

• Herring gull

• Great black backed gull

Although many people call them “seagulls,” there are several distinct gull species along the coast.

Cormorants

Cormorants are dark waterbirds that dive beneath the surface to catch fish.

The double crested cormorant is the species most often seen along Maine’s rocky shores and harbor ledges.

Eiders

Common eiders are large sea ducks that gather in quiet bays and coastal waters. Their soft down feathers have long been prized for insulation.

FAQ: What are the most common birds on the Maine coast?

The most common coastal birds include gulls, terns, cormorants, eiders, and puffins. Many of these species nest on offshore islands and feed in the surrounding ocean waters.

Rare Pelagic Birds Found Offshore

Some birds that live in the Gulf of Maine spend very little time near land. These species are known as pelagic birds, meaning they live primarily on the open ocean.

Examples include:

• Northern gannet

• Black legged kittiwake

• Storm petrels

• Razorbills

• Black guillemots

Because these birds stay far offshore, they are rarely seen from land.

Birdwatchers often travel farther into the Gulf of Maine on dedicated wildlife tours like the Special Pelagic Bird Cruise offered by Cap’n Fish’s Cruises. These trips explore deeper offshore waters where pelagic species gather.

FAQ: What is a pelagic bird?

A pelagic bird is a species that spends most of its life at sea and only comes to land during breeding season. Many pelagic birds are best observed from offshore boat tours.

Best Time to See Birds Along the Maine Coast

Bird activity along the Maine coast changes throughout the year.

Spring

Spring marks the return of nesting seabirds. Puffins, terns, and other birds begin arriving at offshore islands.

Summer

Summer is peak wildlife viewing season. Many seabirds are actively feeding chicks and are easier to observe near nesting colonies.

Fall

Fall migration brings different bird species moving south along the Atlantic Flyway.

For early morning wildlife viewing, many visitors enjoy the Birds & Breakfast Cruise, which combines coastal birdwatching with a relaxing start to the day on the water.

FAQ: When is the best time to see puffins in Maine?

The best time to see puffins in Maine is from late May through early August. This is when the birds return to nesting islands to breed and raise their chicks.

Why Offshore Boat Tours Are Best for Birdwatching

Many of Maine’s seabirds nest on protected islands that are not accessible to the public. Boat tours allow visitors to safely observe these birds without disturbing their habitat.

Benefits of birdwatching by boat include:

• Access to remote nesting islands

• Closer views of wildlife

• Opportunities to see multiple species in one trip

• Expert narration from naturalist guides

Tours like the Whale & Puffin Combo Cruise also offer the chance to see whales, seals, and other marine wildlife alongside seabirds.

FAQ: Can you see whales and seabirds on the same tour?

Yes. Many offshore wildlife cruises in Maine combine whale watching with seabird viewing. Puffins, gulls, and gannets are often seen feeding in the same areas where whales gather.
