rufous-breasted spinetail Synallaxis erythrothorax

Small, long-tailed, rather wrenlike bird of scrubby second-growth thickets and overgrown clearings. Typically rather skulking and heard much more often than seen. Distinctive song is a sneezy “whit’chew” or “whi-whi whit’chew” (“pleased to MEET you!”). Bright rusty breast blends into bright rusty wings and sets off black collar at base of throat. Long, spiny tail and wings lack the dark barring shown by wrens.
