Broad-billed Hummingbird (Cynanthus latirostris) 23 October 2020. Half Moon Bay, San Mateo County, California.
This hatching year male was found by Malia DeFelice and Chris Hayward 22 October 2020 visiting feeders at their residence in Half Moon Bay. This appears to be the second San Mateo County record; the first being a hatching year male 19 October 1986 at Año Nuevo State Reserve. This is a private residence and viewing is by invitation. When we arrived the bird had not been seen for over an hour but fortunately it appeared at the feeder soon after we arrived and I was able to see the bird well and obtain these photos.
Most of the time, the bird was silent, but once it gave a loud chittering call similar to that of Ruby-crowned Kinglet. This hummingbird was about the size of Anna's Hummingbird or slightly larger, but it had a broad-based, long bright red lower mandible with dark tip. The upper mandible was mostly dark with some red at the base and the whole bill was slightly decurved. The underparts were mostly dingy gray with a dark gray smudge across its chest forming a narrow dark band. A patch of iridescent blue feathers was evident in the middle of the throat. The upperparts were iridescent dull bronzy-green. Its face had an obvious white post ocular stripe set off by a broad dark transocular mask. The tail was short, mostly black with gray feather tips, strongly notched and with a strong metallic bluish sheen on the central rectrices. When perched, it tended to hold its wings down, drooping slightly below the tail. Tufts of bright white body feathers were often visible above the bend of the folded wing when the bird was perched in nearby vegetation.
The dull bronzy-green back is consistent with the expected migratory northernmost C. l. magicus breeding in SE Arizona, SW New Mexico and adjacent NW Mexico. The race C. l. doubledayi of Southern Mexico, sometimes recognized as a separate species "Doubleday Hummingbird" has a blue forehead and a longer more deeply forked tail. Another race, sometimes split as Lawrence's Hummingbird, C. l. lawrencei is confined to the Tres Marias Islands off western Mexico. It has a green throat.
