Berylline Hummingbird (Amazilia beryllina)

Trochilus beryllinus

Sometimes placed in genus Saucerottia. Closely related to A. cyanura; reports of hybridization in a small zone of sympatry in Guatemala and El Salvador seem to be unproven, and may be erroneously based on variable tail coloration of present species. Form sumichrasti, long ignored, has proved to represent a well-marked race. Individuals of extreme W subpopulation of nominate race exhibit intergradation towards viola in belly coloration. Proposed race motaguae (from E Guatemala) is invalid, as main distinguishing characters can be ascribed to juvenile or female plumage. Race devillei considered “as distinct as many recognized hummingbird species”#R, but violet-purple vs bronzier-brown tail (score 2) and all glittering-green underparts vs glittering-green breast with greyish-cinnamon belly (2) appear to be only significant points of difference; further research desirable. Five subspecies recognized.
