Migration is one of nature’s most fascinating spectacles, and North America’s flyways are highways in the sky for millions of birds. These invisible routes stretch across the continent, guiding birds as they travel thousands of miles between breeding and wintering grounds. From the icy tundra of Canada to the tropical warmth of Central and South America, these journeys are vital for survival. Along the way, birds rely on stopover sites for food and rest, and their migrations signal the changing seasons. Here are 15 incredible birds that migrate through North America’s flyways.
1. Arctic Tern
The Arctic tern undertakes one of the longest migrations in the animal kingdom, travelling from its Arctic breeding grounds to the Antarctic each year. This incredible round trip spans up to 40,000 miles, crossing multiple flyways along the way. These graceful seabirds rely on abundant food sources like fish to sustain their epic journey. Their stamina and precision make them true masters of migration.
2. Sandhill Crane
Sandhill cranes are iconic migrants of the Central Flyway, known for their long legs, elegant flight, and haunting calls. Each spring and autumn, massive flocks gather along rivers and wetlands to rest and refuel. Nebraska’s Platte River is a critical stopover for these birds, where thousands can be seen in one spectacular gathering. Their migration routes cover distances of up to 5,000 miles.
3. Ruby-Throated Hummingbird
Weighing less than a penny, ruby-throated hummingbirds are marvels of endurance. These tiny birds migrate between North America and Central America, crossing the Gulf of Mexico in a single non-stop flight. Their high metabolism means they must stock up on nectar and insects before their journey. Despite their small size, they are capable of incredible feats of navigation.
4. Snow Goose
Snow geese are striking white birds with black wingtips, often seen in enormous flocks during migration. They travel along the Pacific and Central Flyways, covering distances of over 3,000 miles between Arctic breeding grounds and southern wintering areas. Wetlands and agricultural fields are vital stopovers, where they feed on grains and aquatic plants. Their loud honking calls are a hallmark of autumn and spring skies.
5. Yellow Warbler
Yellow warblers are small songbirds that brighten the skies during their migration through North America’s flyways. These cheerful birds travel from Canada and the United States to Central and South America, flying mostly at night to avoid predators. They rely on forests and shrubs for rest and insects for energy. Their distinctive song is often heard during spring and summer as they return to breed.
6. Peregrine Falcon
Peregrine falcons, known for their incredible speed, are among the many raptors that use North America’s flyways. Some populations migrate thousands of miles between Arctic breeding grounds and South America. These skilled hunters rely on coastal cliffs, open fields, and wetlands to find prey during their journey. Their breathtaking dives can reach speeds of over 240 miles per hour.
7. American White Pelican
The American white pelican is a large, graceful bird that migrates in flocks along the Mississippi Flyway. These birds travel from breeding sites in Canada and the northern U.S. to warmer waters in the south. With their enormous wingspan, they soar effortlessly, often gliding in V-shaped formations. During stopovers, they feed on fish in shallow lakes and rivers.
8. Blackpoll Warbler
The blackpoll warbler embarks on an astonishing migration, flying over 2,000 miles non-stop from North America to South America. Weighing just a few ounces, they store up fat reserves to sustain their journey. These small birds use the Atlantic Flyway, relying on coastal forests and thickets as stopover sites. Their endurance and determination make them one of the most impressive migratory songbirds.
9. Bald Eagle
While some bald eagles are resident year-round, many northern populations migrate to escape harsh winters. Using the Pacific, Central, and Mississippi Flyways, they travel to areas with abundant open water and prey. These majestic birds often follow rivers and lakes, where fish and waterfowl are plentiful. Their migrations showcase their adaptability and resilience.
10. Greater Yellowlegs
The greater yellowlegs is a shorebird known for its long legs and distinctive call. These birds migrate between northern breeding grounds in Canada and wintering areas in Central and South America. Using wetlands and coastal mudflats as stopovers, they feed on small invertebrates. Their elegant flight and recognizable silhouette make them a favourite among birdwatchers.
11. Canada Goose
Canada geese are familiar sights during migration, flying in iconic V-shaped formations. They use all four of North America’s flyways, covering thousands of miles between breeding sites in Canada and wintering grounds in the U.S. and Mexico. These adaptable birds rely on lakes, rivers, and fields for rest and feeding during their journey. Their honking calls are synonymous with seasonal change.
12. Osprey
Ospreys, often called “fish hawks,” migrate along North America’s flyways in search of abundant fishing grounds. These raptors breed near lakes and rivers in the north before heading to Central and South America for the winter. Ospreys are skilled hunters, diving feet-first to catch fish with their sharp talons. Their journey is closely tied to the availability of aquatic habitats.
13. Swainson’s Hawk
Swainson’s hawks undertake one of the longest migrations of any raptor, flying from North America to Argentina. They use the Central and Mississippi Flyways, often forming large kettles of soaring birds during their journey. Grasslands and agricultural fields provide vital food sources, including insects and small mammals. Their adaptability to human-altered landscapes is remarkable.
14. Red Knot
The red knot is a small but hardy shorebird that migrates between the Arctic and southern South America. These long-distance travellers rely on key stopovers like Delaware Bay, where they feed on horseshoe crab eggs to fuel their journey. Their migration spans up to 9,000 miles, making them one of the most remarkable shorebird species.
15. Barn Swallow
Barn swallows are agile insect hunters that migrate through all of North America’s flyways. These birds travel between Canada and the southern hemisphere, covering thousands of miles each year. They are often seen swooping low over fields and water to catch flying insects. During migration, they rest in large communal roosts, creating an impressive spectacle.
