"White-necked Jacobin," Wikipedia, the free encyclopedia. The white-necked jacobin is a large and attractive hummingbird that ranges from Mexico, south to Peru, Bolivia and south Brazil. Other common names are great jacobin and collared hummingbird. The white-necked jacobin is a widespread inhabitant of forest, usually being seen at a high perch or just above the canopy. It is less common at lower levels, except near hummingbird feeders. 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 (the area around the cloaca), or be intermediate between the aforementioned 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.
