Várzeadunkeltyrann Knipolegus poecilocercus

A rarely-encountered medium-sized dark flycatcher, most often found in flooded forests along rivers. Both males and females similar to the related Riverside Tyrant, but that species prefers more open habitat. Male Amazonian Black-Tyrant is shiny-black, smaller and glossier than male Riverside. Female Amazonian are warm brown with streaked underparts, considerably warmer in coloration than female Riverside. Notably quiet for a flycatcher.
