The black-chinned hummingbird (Archilochus alexandri) male has a black face and chin, a glossy purple throat band and a dark forked tail. The female has a dark rounded tail with white tips and no throat patch. Black-chinned hummingbirds are found in most of the western USA, reaching north into Canada in Alberta and British Columbia, east to Oklahoma, and as far south as Mexico. However, the Black-chin is almost entirely absent from the west in winter.
