Plain-winged woodcreeper
The plain-winged woodcreeper or thrush-like woodcreeper is a passerine bird belonging to the woodcreeper group, now classified in the ovenbird family, Furnariidae. It is sometimes considered to be a subspecies of the plain-brown woodcreeper.
It is 20-21 centimetres long. It is mostly plain brown with no markings apart from faint buff streaks on the crown, a buff throat and a chestnut tail. The bill is fairly short and straight. The song is long and monotonous. The plain-brown woodcreeper is similar in appearance but has rufous wings, rump and tail.
It occurs in eastern Brazil from Rio Grande do Sul north to Bahia. It is also found in north-east Argentina and eastern Paraguay. It inhabits the lower and middle levels of forest and woodland from the coast into the foothills. It feeds on arthropods and often follows army ant swarms in order to catch prey flushed by the ants. Unlike most woodcreepers, it will make sallies to catch insects in flight or snatch them from leaves.
