This 30-32 cm long snipe
Snipe
A snipe is any of about 25 wading bird species in three genera in the family Scolopacidae. They are characterized by a very long, slender bill and crypsis plumage. The Gallinago snipes have a nearly worldwide distribution, the Lymnocryptes Jack Snipe is restricted to Asia and Europe and the...

 has a stocky body and relatively short legs for a wader. Its upperparts, head and neck are streaked and patterned with warm brown and buff, and the gold edges to the feathers form lines down its back, which are not as sharply defined as in most snipe species. The belly is white with brown barring. The horn-colored bill is long, straight and fairly robust. The legs and feet are yellowish-green. The sexes are similar, and immatures differ only in showing pale fringes on the wing coverts.

The Andean Snipe makes a whee-tschwu call in its display flight.
Compared with other snipe with an overlapping range, Andean Snipe is obviously larger, with a heavy woodcock-like

 which occurs in the lower Andes, Gallinago andina, has yellow legs.

Behaviour



The Andean Snipe is found in marshy areas where grassland and forest intergrade, at altitudes ranging between 2,100 - 3,800 m (mostly 3000-3500 m). Little is known of its behaviour, but it has an aerial display, which involves flying high in circles, followed by a dive during which the bird makes a drumming
Drumming (snipe)
Drumming is a sound produced by snipe as part of their courtship display flights. The sound is produced mechanically by the vibration of the modified outer tail feathers, held out at a wide angle to the body, in the slipstream of a power dive. The display is usually crepuscular, or given...

sound, caused by vibrations of its modified outer tail feathers.

The Andean Snipe forages by pushing its long bill deep into the mud seeking insects and worms. Its cryptic plumage provides effective camouflage when the bird stands motionless amongst marsh vegetation.

Status

The Andean Snipe has a large range, with an estimated extent of 260,000 km², but the population size is unknown. It is probably not rare, but is well concealed by its cryptic plumage and habitat, and difficult to flush. It is usually only seen on its display flight.
