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.
