A small passerine bird with black-and-white plumage. The head, upperparts, and tail are black. The sides of the neck and underparts are white. The wing shows a prominent white slash, and the outer tail feathers are white. The bill is black and the upper mandible is hooked at the tip. Usually found in mixed-species foraging flocks, feeding on insects in the mid-canopy by hawking prey in mid-air like flycatchers, hence the name. Inhabits a wide range of forested habitats. Song is a sweet-sounding series of bouncing notes: “tsilikee-tsilikee-tsilikee!”
