seabird

A white spoonbill of Australasia known for the long, trailing white crest plumes that breeding adults grow from the back of the head.
wading bird
Northern Royal Albatross
One of the largest albatrosses, a mostly white southern seabird with a predominantly black upperwing edged in white, closely related to the Wandering Albatross group.
seabird
Elegant Tern
A slender, crested Pacific coast tern with a notably long, thin, slightly drooping orange-yellow bill, intermediate in size and appearance between the Royal and Sandwich Terns.
seabird
Whiskered Tern
A compact marsh tern that turns a striking dark slate-gray across the body in breeding plumage, with a crisp white stripe dividing the black cap from the gray cheek.
seabird
Little Tern
The Old World counterpart to the Least Tern, a tiny, fast-flying species of European, African, and Asian coasts, distinguished by its small size, yellow bill, and bold white forehead patch.
seabird
Bridled Tern
A pelagic tropical tern closely related to the Sooty Tern but browner above with a distinctive white collar around the back of the neck, generally encountered further from shore than most coastal terns.
seabird
Black Tern
A distinctive marsh tern that turns almost entirely sooty-black during the breeding season, a striking departure from the pale gray-and-white pattern typical of most terns.
seabird
Least Tern
The smallest tern in North America, a diminutive, fast-flying species of sandy beaches and river sandbars, easily told by its small size, yellow bill, and white forehead patch above the black cap.
seabird
Sooty Tern
A highly pelagic tropical seabird that spends years continuously at sea outside the breeding season, recognized by its blackish upperparts, crisp white underparts, and deeply forked tail.
seabird
Sandwich Tern
A slender, crested tern of sandy coastlines, easily recognized by its shaggy black crest and long, slim black bill with a distinctive yellow tip.
seabird
Roseate Tern
A pale, elegant tern with unusually long tail streamers and a delicate pink blush to the breeding-season underparts, generally scarcer and more restricted to select coastal colonies than its close relatives.
seabird
Forster's Tern
A North American marsh tern with notably pale, frosty primaries and a distinctive nonbreeding head pattern featuring a dark patch through the eye rather than a full black cap.
seabird
Common Tern
A widespread and familiar tern of coasts and inland waters, identified by its black cap, forked tail, red-orange bill with a black tip, and a dark wedge along the leading edge of the outer wing.
seabird
Caspian Tern
The largest tern in the world, approaching the size of some gulls, unmistakable for its massive deep red bill, heavy build, and loud, harsh call.
seabird
Arctic Tern
A slender, long-distance migrant famous for traveling between Arctic breeding grounds and Antarctic waters each year, distinguished from the similar Common Tern by an all-red bill and more uniformly translucent primaries.
seabird
Gull-billed Tern
A stocky, pale tern known for its short, thick, gull-like black bill rather than the slender dagger bill typical of most terns.
seabird
Yellow-billed Spoonbill
An Australian endemic spoonbill with pale yellow bill and legs, generally less gregarious than the Royal Spoonbill and often found alone or in small groups at inland wetlands.
wading bird
Little Gull
The smallest gull in the world, a delicate Eurasian species with rounded wings, a buoyant tern-like flight, and strikingly dark underwings that flash as it wheels over the water.
seabird
Bonaparte's Gull
A dainty, tern-like gull of the North American boreal forest, notable as one of the few gulls that nests in trees, and identifiable by its crisp black hood and bright white wing wedge.
seabird
Brown Noddy
A dark, tropical seabird related to terns, easily told by its uniform chocolate-brown plumage set off by a pale gray-white cap and a long, wedge-shaped tail.
