Zeledon Karıncakuşu Hafferia zeledoni

A nondescript antbird; male entirely black and female entirely dark brown. Only notable feature is the pale blue skin around the eye on both sexes. Listen for loud song, a series of even whistled notes. Rather large and chunky. Look for the tail being raised and lowered slowly. Typically found in pairs in the dark forest understory, sometimes following a mixed flock or ant swarm.
