Hellkehl-Stachelschwanz Premnoplex brunnescens

A small dark bird that creeps around mossy forest understory, frequently hanging upside-down like a nuthatch. Overall dark brown with warm buffy throat and spotting down the chest. Sexes alike. Combination of dark plumage, behavior, and spotting render this species distinctive. Found singly or in pairs, often following a mixed flock through the forest. Listen for its fast, descending, tinkling trill.
