The White-necked Jacobin (Florisuga mellivora). The White-necked Jacobin is a widespread inhabitant of forest, usually being seen at a high perch or just above the canopy. 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 be intermediate between the aforementioned plumages, though retain the white-scaled dark blue crissum.
A delight to watch, and photograph... amazing how territorial they are, and if one studies them for a bit, you can almost certainly determine there next perch/resting location.... Click on image to darken,,,,,
