Female Archilochus hummingbirds do not show the white supraloral stripe evident in female Calypte hummingbirds.
Female Ruby-throats have a shorter bill, greener crown and narrower outer primaries compared to female Black-chinned.
Female Costa's are grayer above, whiter below and longer-billed than female Anna's. Calypte is the only
hummingbird genus in which the birds habitually sing from a perch.
