6-letter Birds that contain U

List of 6-letter Birds that contain U

1

Cuckoo

Cuculus canorus (common cuckoo)

A medium-sized bird famous for its distinctive call (the basis of cuckoo clocks) and brood parasitism — laying eggs in other species' nests to be raised by unwitting foster parents.

2

Curlew

Numenius arquata

Europe's largest wading bird — recognised by its extraordinarily long, downcurved bill and haunting bubbling call; a moorland and coastal bird facing serious population decline across its range due to habitat loss and predation of ground nests.

3

Dunlin

Calidris alpina

Britain's most abundant small wader — a dumpy, short-legged sandpiper that winters in enormous flocks on estuaries and mudflats, performing breathtaking aerial "murmurations" that twist and turn as a single organism; in summer breeding plumage it has a distinctive black belly patch unique among similar species.

4

Grouse

Tetraonidae (subfamily, sometimes treated as family)

A family of plump ground-dwelling birds adapted to cold climates — including iconic species like ruffed grouse, sage grouse, and ptarmigan, with elaborate dramatic mating displays in many species.

5

Puffin

Fratercula arctica (Atlantic puffin)

A small black-and-white seabird with a colorful triangular bill — capable of holding 10+ fish in its beak at once, nesting in cliff burrows by the millions, and increasingly threatened by warming oceans.

6

Thrush

Turdidae (family)

A diverse family of medium-sized songbirds known for melodious songs and ground-foraging — with the American robin, European blackbird, and song thrush as the most familiar members of a globally distributed family.

7

Toucan

Ramphastos toco

The largest toucan species, a Central and South American fruit-eater with a striking oversized orange bill that serves as a thermal radiator as well as a feeding tool.

8

Turkey

Meleagris gallopavo

A large North American gamebird domesticated by Indigenous Americans, surviving through the European-introduced Christmas-and-Thanksgiving traditions, with wild populations recovering to abundance after near-extinction.
