Humboldt’s Sapphire

Humboldt's sapphire or Humboldt's hummingbird (Chrysuronia humboldtii) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Colombia, Ecuador, and Panama. == Taxonomy and systematics == Humboldt's sapphire was formerly placed in the genera Hylocharis and Amazilia. It was moved by most taxonomic systems to Chrysuronia based on the results of a molecular phylogenetic study published in 2014. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia. At one time the species was treated as a subspecies of the blue-headed hummingbird (C. grayi). Humboldt's sapphire is monotypic. == Description == Humboldt's sapphire is 9 to 12.5 cm (3.5 to 4.9 in) long. Males weigh 6.3 to 6.6 g (0.22 to 0.23 oz) and females 5.8 to 6.4 g (0.20 to 0.23 oz).

Adult males have a deep blue forehead and center of the throat. Their crown is dull dark blue-green and the rest of their upperparts metallic green to bronze-green. Their tail is dark metallic green…
