Identification Tips: Black-chinned Hummingbird
- Small hummingbird
- Long, straight, thin bill
Adult male:
- Bright green back and crown
- Entirely dark tail
- White underparts with greenish flanks
- Black face, chin, and upper throat
- Iridescent purple gorget at lower throat
Female/Immatures:
- Green back and crown
- White chin and throat with variable amounts of thin dark
streaking
- White underparts
- Dark tail with white tips on outer tail feathers
Similar species:
Males unmistakable with a good view. Females are
similar to a number of other female hummingbirds, and are best told
from the Calliope Hummingbird and species in the genus Selasphorus
by their lack of rufous on the flanks and in the tail. Anna's
Hummingbirds are larger and have grayer chests, while Costa's
Hummingbirds differ only in subtleties of facial pattern and tail
pattern. Black-chinned Hummingbird females are not safely
separable from female Ruby-throateds except in the hand. Best told
from all species except Ruby-throated Hummingbird by call.

Identification Tips: Anna's Hummingbird
- Medium-sized hummingbird
- Long, straight, thin bill
Adult male:
- Bright green back
- Entirely dark tail
- Gray underparts with greenish flanks
- Rosy-red iridescent crown and gorget
Female/Immatures:
- Green back and crown
- Gray chin and throat with variable amounts of thin dark
streaking or rosy red spots depending on age and sex
- Gray underparts
- Dark tail with white tips on outer tail feathers
Similar species:
Males unmistakable when red crown is seen but
beware of poor lighting conditions. Females and immatures are
fairly large and gray breasted, and often show the distinctive
rosy-red gorget color on the throat. Costa's and the two
Archilochus hummingbirds are the most likely
identification contenders, but are smaller with whiter breasts and
different call notes.
BACK
Identification Tips: Costa's Hummingbird
- Small hummingbird
- Long, straight, thin bill
Adult male:
- Bright green back
- Entirely dark tail
- White underparts with greenish flanks
- Iridescent purple crown and gorget, with long pointed extention
far down neck
Female/Immatures:
- Green back and crown
- Dark mask on face through eye
- White chin and underparts
- Dark tail with white tips on outer tail feathers
Similar species:
The adult male Lucifer Hummingbird is similar in
plumage to the adult male Costa's, but is easily separated in the
narrow zone of overlap between the two species by its strongly
decurved bill and forked tail. The female Lucifer is strongly
buffy below and has a decurved bill and forked tail.
The female Costa's is similar to the female and immature Anna's,
but typically is smaller, with a cleaner throat and whiter
underparts. Archilochus hummingbird females are also similar but
tend to have streaked throats. Female Costa's are separable also
by subtleties of tail pattern and call notes.
BACK
Identification Tips: Calliope Hummingbird
- Very small hummingbird
- Relatively short tail does not extend past wings at rest
- Relatively short bill
Adult male:
- Bright green back and crown
- White underparts
- Greenish flanks
- Gorget composed of purple-red streaks on white background
- Green taiil
Female/Immature:
- Green back and crown
- Green tail with dark subterminal markings and white tips to outer
tail feathers
- White chin and throat with thin dark streaking
- White underparts with pale salmon wash on flanks
- Dark tail with a trace of rufous color and white tips on the
outer tail feathers
Similar species:
The smallest North American hummingbird, females
are best separated by their short tail and small size. The rufous
wash on the flanks should safely separate females and immatures
from all species except the three Selasphorus hummingbirds, which
all typically have much more rufous in the tail. The streaked
gorget of adult males should make them instantly identifiable.
Calliope is the only species where the tail does not extend past
the wings when at rest.
BACK
Identification Tips: Rufous Hummingbird
- Small hummingbird
- Long, straight, thin bill
Adult male:
- Rufous back, flanks, rump, and tail
- Occasionally variants occur with greenish backs and crowns
- Brownish-red crown and face
- Bright red gorget
- White breast
Adult female:
- Green back and crown
- White underparts
- White throat variably marked with dark streaks (immatures)
or central group of red spots (adult females)
- Rufous wash on flanks
- Immature males similar to adult female but central tail feathers
like adult male (rufous with dark tips)
- Dark tail with rufous at the bases of the retrices, and white
tips on the outer three retrices
Similar species:
Adult males can be confused only with Allen's
Hummingbird. Rufous-backed males are certainly Rufous
Hummingbirds, but care should be taken as some Rufous have
variable amounts of green on the back and crown. Females and
immatures are easily identified as a Selasphorus by the rufous in
the tail. Female and immature Broad-tailed Hummingbirds have
less rufous on the inner tail feathers, whitish, not rusty undertail
coverts and more blue-green backs, as well as being larger with
different calls. Female and immature Calliope Hummingbirds
are smaller with shorter bills and less rusty backs. Rufous and
Allen's females and immatures are inseparable in the field.
BACK
Identification Tips: Allen's Hummingbird
- Small hummingbird
- Long, straight, thin bill

Green back and crown Brownish-red face
Bright red gorget White breast
Adult female:
- Green back and crown

- Immature males similar to adult female but central tail feathers

- Dark tail with rufous at the bases of the retrices, and white
tips on the outer three retrices
Similar species:
Some adult male of Rufous Hummingbirds
have variable amounts of green in the back and crown. Females
and immatures are easily identified as a Selasphorus by the rufous
