Iridescent feathers on
crown and above eye eliminated all hummingbirds except Costa's. The
color of the iridescent feathers was deep pink to rosy red, not violet,
ruling out Costa's. The measurements and overall size of the bird were
larger than Costa's. Dark rachis extended into white tip of R5s. |
