Beautiful little flycatcher with a spiky crest found in the Andes of northern Peru, just barely reaching over the border into southern Ecuador. Male is quite distinctive with a solid black face, black-and-white streaking, and a long crest that sticks up in front of its white crown. Female and immature are grayer with less contrasting plumage and shorter crest; the orange bill might lead to confusion with Yellow-billed Tit-Tyrant, but Black-crested lacks brown on the back and yellow on the belly. Very similar to Pied-crested Tit-Tyrant, but Black-crested has broader white tips to the tail; also note its more northern range. Inhabits scrub and light woodland, often giving squeaks and rapid trills.
