Description – The stunning broad-billed hummingbird (Cynanthus latirostris) is a diurnal bird, displays sexual dimorphism, also identified for its other common name – the Colibrí Pico Ancho in Spanish and Colibri circé in French. Despite its name, the bill of the broad-tailed, glitteringly iridescent Broad-billed Hummingbird is no broader than that of many of its close relatives.
Identification – The blue of the male’s throat and upper breast varies regionally from deep indigo to turquoise across the five subspecies and is most extensive in the slightly smaller males of the Pacific lowlands of southern Mexico (subsp. doubledayi). Usually, the male hummingbird has a vibrant red color bill, that has a black tip. The Male has a blackish-blue tail which is a little broad. In-flight, the feather turns into brownish Grey.
Females are similar to the closely related Chlorostilbon emeralds, with gray underparts, pale belly, prominent white eye stripes face markings, and white tips on the outer tail feathers. With the passage of time, juvenile male bird bill turns into reddish and iridescent feathers.
Northern populations are partially migratory, moving north and inland during the breeding season. The winter range has expanded with the increasing prevalence of feeders and winter-blooming hummingbird gardens in the southern and southwestern United States. Post-breeding wanderers have been recorded in the Great Lakes region, southeastern Canada, the Rocky Mountains, and the Pacific flyway.
Distribution – The broad-billed hummingbird is usually found in Mexico and the United States. There are found subspecies of Broad-billed Hummingbird. The Subspecies C.I. latirostris occurs in east-central Mexico; subspecies C.I. lawrencei is restricted to the Marías Islands off the western coast of Mexico; subspecies C.I. magicus ranges from the southwestern United States to central-western Mexico; subspecies C.I. propinquus occurs in central Mexico. However, there is doubt about subsp C.I. doubledayi occurs in southern Mexico, normally treated as its own species.
