diademed tapaculo Scytalopus schulenbergi

Tiny gray bird with a short, stubby tail. Pale gray forehead and eyebrow form its namesake crown-like pattern, and distinguish the species from similar tapaculos; however, this gray pattern can be reduced and hard to see in females. Found in dense mossy undergrowth in elfin forest near the treeline. Extremely shy and heard far more often than seen; listen for its song, a loud, accelerating series of nasal complaining notes.
