Slaty-capped Flycatcher

The slaty-capped flycatcher (Leptopogon superciliaris) is a small passerine bird in the tyrant flycatcher family. It is found from Costa Rica south to Bolivia and east to Venezuela and Trinidad. == Taxonomy and systematics == The slaty-capped flycatcher's taxonomy is unsettled.

The Clements taxonomy assigns a third, L. s. transandinus, that the IOC includes within the nominate. BirdLife International's Handbook of the Birds of the World (HBW) treats albiventer as a separate species, the white-bellied flycatcher, leaving the slaty-capped as a monotypic species. Several other subspecies have been suggested but not recognized. This article follows the IOC one species, two subspecies model. == Description == The slaty-capped flycatcher is 13 to 14 cm (5.1 to 5.5 in) long and weighs 9.5 to 14.8 g (0.34 to 0.52 oz). The sexes have the same plumage. Both subspecies show much plumage variation within them. Adults of the nominate subspecies have a slaty gray crown. They have white lores, a thin white supercilium, and a wide dusky to black crescent around the back of the otherwise mottled whitish face. Their back…
