Broad-billed Hummingbird
Cynanthus latirostris
The broad-billed hummingbird is a small hummingbird about 8–10 cm (3.1–3.9 in) long. It weighs only 3–4 grams, with the male weighing slightly more than the female. The wingspan of this hummingbird is about 13 cm (5.1 in). It has a long, bright reddish coloured bill that has a black tip. The birds are metallic green dorsally with dull colouring on the crown and forehead. The hummingbird is sexually dimorphic, with male and female adults appearing significantly different. The male is dark green with white undertail-coverts and a blue throat or gorget. Voice: The C. latirostris chatter is done by both the male and the female. Like the note of a Ruby-crowned Kinglet (Regulus calendula), the chatter sounds like a rapid chi-dit. This noise can be done while perching or in flight. The males display call is a whining zing - but little is known about its song.

Golden-crowned Emerald
Cynanthus auriceps
The golden-crowned emerald is 7.5 to 9.5 cm (3.0 to 3.7 in) long and weighs about 2.2 g (0.078 oz). The adult male's crown is brilliant golden green and the rest of its upperparts duller golden green to bronzy green. Its underparts transition from an almost pure green on the chin and throat to brilliant golden green at the vent. The tail is long and deeply forked; its feathers are black with a violet-bluish gloss, and the central three pairs have broad brownish gray tips. The adult female's upperparts are like the male's. Its underparts are light gray that is palest on the belly and vent. Voice: The golden-crowned emerald has "dry, rattling and chattering calls".
