Tom Dempsey photographed this female White-necked Jacobin (Florisuga mellivora; or Great Jacobin; or Collared Hummingbird) hummingbird at the lower elevations (about 1400 meters) of Bellavista Cloud Forest Reserve, near Quito, Ecuador, South America. This large and attractive hummingbird ranges from Mexico south to Peru, Bolivia and south Brazil. The approximately 12 cm long male White-necked Jacobin is unmistakable with its white belly and tail, a white band on the nape and a dark blue hood. Immature males have less white in the tail and a conspicuous rufous patch in the malar region. Females are highly variable, and may resemble adult or immature males, have green upperparts, white belly, white-scaled green or blue throat, and white-scaled dark blue crissum, or have intermediate plumages, though retain the white-scaled dark blue crissum. Females are potentially confusing, but the pattern on the crissum is distinctive and not shared by superficially similar species. These birds usually visit flowers of tall trees and epiphytes for nectar, and also hawk for insects.
