White-necked Jacobin (male)
Boca Tapada, Alajuela Province | Costa Rica
The White-necked Jacobin is a relatively large, widespread hummingbird species that ranges from Mexico through Central America, south to Peru, Bolivia and southern Brazil. Subspecies are also found on Trinidad and Tobago. As previously noted, the male of this species is unmistakable with his royal-blue head and white neck. The same cannot be said of the female as plumage can be highly variable. In the main they’re usually green above and white below with greyish scaling on the throat and breast - not dissimilar to females of a few other species, such as the Blue-chested Hummingbird and Green-crowned Brilliant.
