Costa's Hummingbird Identification

Adult male

Small and compact hummingbird with a hunched posture and a short tail. The male's iridescent purple gorget (throat patch) flares out along the sides of the neck like an overgrown mustache.

Female

When perched the wings barely extend beyond the tail on this tiny, compact hummingbird. Females are greenish above with a white eyebrow stripe, a grayish cheek patch, and whitish underparts.

Adult male

Gorget color is dark purple, and feathers extend off the sides of the throat. Fairly short wings; wingtips barely extend past the tail.

Adult male

Males repeatedly perch at 3–4 favorite spots within their territory, usually a dead twig in a palo verde, acacia, or ironwood, and sing a thin high-pitched whistle to proclaim ownership and keep intruders out.

Immature male

Immature males have variable amounts of adult gorget feathers coming in on the neck. Note whitish underparts and green washing on the sides.
