About the Azure-crowned Hummingbird
The azure-crowned hummingbird (Saucerottia cyanocephala) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Belize, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua.
The azure-crowned hummingbird was originally described as Ornismya cyanocephalus and later moved into genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the azure-crowned hummingbird was moved by most taxonomic systems to the resurrected genus Saucerottia. However, BirdLife International's Handbook of the Birds of the World retains it in Amazilia.
The azure-crowned hummingbird is 10 to 11.5 cm (3.9 to 4.5 in) long. Males weigh an average of about 5.8 g (0.20 oz) and females average about 5.4 g (0.19 oz). The bills of both sexes of both subspecies have a black maxilla and a dull pink mandible with a black outer third. Within a subspecies the sexes are almost alike. Adult... Wikipedia →
