Feather & Bird Encyclopedia
Search and identify feathers by species — with feather type, plumage, colours, size, habitat, and how to tell them apart in the field.

Rock Pigeon
A stocky, familiar city bird whose feather color is famously variable, though wild-type individuals retain a blue-gray body with two dark wingbars and an iridescent green-purple neck.
dove pigeon
Cedar Waxwing
A sleek, crested bird best known for the small, waxy red tips on its secondary wing feathers, paired with a soft brown-to-gray body and a bright yellow band across the tail tip.
songbird
American Robin
The American Robin is a familiar thrush whose warm orange breast feathers and plain gray-brown back feathers make it one of the easiest yard birds to identify from a single dropped feather.
songbird
Scaled Quail
A pale, scaly-plumaged quail of arid grassland in the southwestern United States and Mexico, easily recognized by its overall bluish-gray tone and a fluffy white crest sometimes called a cottontop.
gamebird
Varied Thrush
A strikingly patterned thrush of Pacific Northwest forests, combining a slate-gray back with burnt-orange underparts, eyebrow stripe, and wing bars, plus a bold dark breast band in males.
songbird
Stilt Sandpiper
A long-legged, long-billed sandpiper whose breeding-plumage feathers are boldly barred across the underparts, giving it a strikingly different look from the plain grays of its winter attire.
shorebird
Purple Sandpiper
A stocky, dark-plumaged sandpiper of wave-battered rocky coastlines, its feathers showing a subtle purplish gloss on slaty-gray upperparts unlike any other North Atlantic shorebird.
shorebird
Flammulated Owl
A tiny, highly secretive migratory owl of western pine forests, camouflaged to match bark with a fine mottled gray-and-rufous pattern, and unusual among small owls for its dark eyes.
owl
Eurasian Pygmy-Owl
Europe's smallest owl, a boreal forest specialist that hunts small birds and rodents largely by day. Its feathers are gray-brown to rufous with crisp white spotting and a narrowly barred tail.
owl
Heermann's Gull
A distinctively dark-bodied Pacific coast gull with a bright red bill, most easily recognized outside the nesting season by its uniform sooty-gray plumage contrasting with a white head.
seabird
Gyrfalcon
The largest falcon in the world, a powerful hunter of the high Arctic occurring in white, gray, and dark plumage morphs, all sharing broader wings and greater bulk than any other falcon.
raptor
Golden-winged Warbler
A striking blue-gray warbler with a bright yellow crown and wing patch, set off by a bold black throat and facial mask in adult males, known for hybridizing with the Blue-winged Warbler.
songbird
Bank Myna
A bluish-gray South Asian myna with warm brick-colored underparts and a distinctive patch of bare orange-red skin behind the eye, often found nesting in burrows along riverbanks.
songbird
Thick-billed Longspur
The Thick-billed Longspur is a shortgrass prairie songbird whose breeding males show a black cap and breast crescent set against gray-brown plumage, identified partly by its notably stout bill.
songbird
Eurasian Woodcock
The larger Eurasian relative of the American Woodcock, sharing the same dead-leaf camouflage pattern and forest-floor lifestyle, but with a grayer overall tone and a distinctive slow, owl-like display flight known as roding.
shorebird
California Gull
A medium-large gull of the American West, the California Gull shows medium gray back feathers and dark eyes, and is notable historically for its role in protecting early Utah crops from insect swarms.
seabird
Black-legged Kittiwake
A truly pelagic gull that spends most of its life far out at sea, recognized by its clean gray-and-white plumage, black legs, and wingtips that look as though they were dipped in black ink.
seabird
Sooty Owl
A dark, striking barn-owl relative of Australian and New Guinean rainforest, its sooty gray-black feathers finely speckled with silvery white, unlike any other owl in its range.
owl
Western Gull
A heavily built, dark-backed gull of the Pacific coast, the Western Gull shows dark slate-gray mantle feathers and a notably powerful, thick bill, rarely wandering far from saltwater.
seabird
Terek Sandpiper
A distinctive sandpiper with a long, strongly upturned bill and short orange-yellow legs, the Terek Sandpiper shows plain pale gray-brown feathers with a dark scapular streak and an animated feeding style.
shorebird
Blue-winged Warbler
A bright yellow-headed warbler with blue-gray wings marked by two white wing bars and a thin black line through the eye, closely related to and often hybridizing with the Golden-winged Warbler.
songbird
Glaucous-winged Gull
A common gull of the North Pacific coast, the Glaucous-winged Gull shows pale gray wingtip feathers with little or no black, differing subtly from most other large gulls, and frequently hybridizes with related species.
seabird
Tropical Parula
A tiny blue-gray and yellow warbler of the far southern U.S. and Latin America, easily told from its northern cousin by its unbroken olive back patch and lack of white eye crescents.
songbird
Peregrine Falcon
A powerful, fast-flying falcon found on nearly every continent, famous for high-speed hunting stoops and identified by its slate-gray back, bold black facial 'moustache,' and finely barred underparts.
