Woodcock (American Woodcock or Eurasian Woodcock); also known as the Timberdoodle, Night Partridge, or Bog Sucker.

The American Woodcock is a plump, short-legged shorebird with a very long bill and large eyes set far back on its head. Its plumage is a masterpiece of dead-leaf camouflage. This specific feather is famous for the 'whistling' sound it produces during the male's spectacular 'sky dance' aerial displays.

Rich earthy tones: a base of warm chocolate brown with a distinct cream or buff-colored longitudinal stripe along the inner vane. The tip is dark brown to blackish.

Densely interlocked (pennaceous) to withstand the wind resistance during display flights. The leading edge barbs are very short and stiff, creating a rigid vane.

Very stiff and slightly glossy. Unlike typical soft flight feathers, these outer primaries have a firm, blade-like texture.

Extreme attenuation (narrowness) and the specific buff-colored inner stripe. No other North American bird has flight feathers quite this narrow and blade-like.

Young forests, shrublands, and old fields near moist soils. They require open areas for mating displays and dense thickets for diurnal resting.

Eastern North America, from Atlantic Canada south to the Gulf States, migrating between northern breeding grounds and southern wintering areas.

An important invertivore that primarily eats earthworms. They serve as an indicator species for the health of young-forest ecosystems.

Common Snipe (Gallinago gallinago) feathers are broader and lack the extreme narrowing; other shorebirds lack the specific earthy-brown and buff longitudinal coloration.

The whistling sound heard during a woodcock's flight isn't vocal; it is 'mechanical music' created by air rushing through these three narrow outer primary feathers.

Good; some slight separation of the barbs near the base (plumulaceous area), but the main pennaceous vane remains intact and the color is vibrant.
