The rufous-bellied seedsnipe (Attagis gayi) is a bird in suborder Scolopaci of order Charadriiformes, the shorebirds. It is found in Argentina, Bolivia, Chile, Ecuador, and Peru. Taxonomy and systematics The rufous-bellied seedsnipe shares its genus with the white-bellied seedsnipe (A. malouinus). They and the other two seedsnipes are closely related to the sandpipers of family Scolopacidae. It has three subspecies, the nominate A. g. gayi, A. g. latrelillii, and A. g. simonsi. At least one publication has suggested that A. g. latrelillii might deserve to be recognized as a species. The rufous-bellied seedsnipe's specific epithet commemorates the French naturalist Claude Gay. Description The rufous-bellied seedsnipe is long and weighs about . The sexes are alike. The nominate subspecies' upperparts have an intricate scallop pattern of rufous-brown and blackish; its underparts are unmarked pale pinkish cinnamon. Subspecies A. g. latrelillii has a deeper rufous cinnamon than the nominate in its vent area and a scalloped breast. A. g. simonsis breast is a darker pinkish cinnamon than the nominate's; it is paler above with finer markings. Juveniles much resemble adults but with somewhat finer markings on their upperparts. Distribution and habitat Subspecies A. g. latrelillii of rufous-bellied seedsnipe is found far from the other subspecies, on seven high volcanoes in north-central Ecuador. A. g. simonsi is found from central Peru south through northern Chile and western Bolivia into northwestern Argentina. The nominate A. g. gayi is found from north central Chile and west central Argentina south almost to Tierra del Fuego. The rufous-bellied seedsnipe inhabits alpine terrain in the Andes, often as high as the snow line. It frequents boggy and other moist areas but also occurs in drier and rockier landscapes. Subspecies A. g. latrelillii is typically found in páramo. In the northern half of its range it mostly is found between . Further south it occurs down to and in the extreme south as low as . Behavior Movement The rufous-bellied seedsnipe is essentially non-migratory, though southern populations are thought to move to lower elevation in the austral winter. It is a strong flier and when flushed flies in a fast zigzag. Feeding The rufous-bellied seedsnipe feeds on plant matter, typically in moist areas, but details of its diet are lacking. Breeding Little is known about the rufous-bellied seedsnipe's breeding biology. It lays eggs during September and October in Chile; further north the season extends to December. Its nest is
