The black-cheeked wood warbler ( Basileuterus melanogenys ) is a small songbird from the wood warbler family (Parulidae).
Black-cheeked warbler reach a body length of 13.5 centimeters. The wing length is 5.9 to 6.6 centimeters in the male and 5.4 to 6.5 centimeters in the female. Adult black-cheeked warblers have a reddish brown crown, a black cheek area and a wide white superciliar stripe , which is bordered at the top by a thin black superciliar stripe and both of which run down to the neck. The upper side plumage is olive to olive gray, the lower side plumage yellow white and the breast and flanks olive gray. Fledglings have a pale, olive stripe of superciliar, which begins behind the eye and ends in the neck, an olive-brown upper side plumage and a grayer throat and chest plumage.
The distribution area extends from Costa Rica to Panama . Black-cheeked warblers live in pairs or in small groups in mountainous oak forests with dense bamboo undergrowth from a height of 2500 meters; however, they occasionally occur up to an altitude of 1600 meters. They feed mainly on insects and spiders , occasionally also on berries .
