Seen but NOT photographed were:
Berylline Hummingbird (Amazilia beryllina)
Rufous Hummingbird (Selasphorus rufus)
Broad-billed Hummingbird (Cynanthus latirostris):
immature male...blueish tail striking in flight; relative lack of white in tail tip seem to rule out female
White-eared Hummingbird (Hylocharis leucotis):
Violet-crowned Hummingbird (Amazilia violiceps):
Blue-throated Hummingbird (Lampornis clemenciae):
Magnificent Hummingbird (Eugenes fulgens):
Black-chinned Hummingbird (Archilochus alexandri):
I believe this to be a young male Black-chinned. Pointing to Archilochus are small-headed look, narrow inner primaries, and whitish underparts. Whitish tips to many body feathers indicate a young bird. Any comments?
Anna's Hummingbird (Calypte anna):
female Anna's, unsure of age...grayish underparts with a bit of green on the sides, plus a hint of gray-green on the undertail coverts help ID this as Anna's from these photos
I'm calling this bird an Anna's after taking some time to consider Broad-tailed. I'm basing that mainly on the primary molt (Broad-tailed molts on wintering grounds with primary molt generally Oct-Jan per Howell), apparent gorget color, and underpart color/pattern. An immature male Broad-tailed at this date would show cinnamon in the flanks and little or no color on the gorget.
a dingy, worn adult female Anna's, with little/no rose on gorget, perhaps a one-year-old bird?
Costa's Hummingbird (Calypte costae):
Broad-tailed Hummingbird (Selasphorus platycercus):
Apparent HYBRID hummingbird (Costa's x Lucifer???). While watching the feeders at Mary Jo's in Ash Canyon, I heard a singing Costa's Hummingbird. Upon tracking the bird down, I was surprised to see a bird that generally resembled a Costa's but had a noticeably long tail. It sang repeatedly while I was observing it.
Since it was singing a typical Costa's song the bird is obviously part Costa's...but its long tail, projecting well beyond the UTCs, tells us that this is no pure bird. Due to the poor quality of the photos, it is difficult to discern exact plumage details. Lucifer Hummingbird breeds nearby, and it makes one wonder if that is the other parent. The long tail with a slight fork supports that. The bill is a bit longish and slightly decurved, but this may be within range of Costa's?
Please feel free to comment on these identifications, particularly the age/sex of certain birds.
