The male Black-throated Blue Warbler is instantly recognizable. Females are rather nondescript but the small white patch in the wing is diagnostic. When this patch is absent, look for the dark cheek patch contrasting with the white supercilium. The unstreaked underparts and lack of wing bars are also helpful field marks.
