Florisuga mellivora or white-necked jacobin (female) Hummingbird nº2 take 1 Nicolas Reusens© This large and attractive White-necked Jacobin has a wide range, from southern Mexico south to Peru, Bolivia and south Brazil. It is also found on Tobago and in Trinidad, but breeding has not been proved on the latter island. It mainly occurs below 900m. They are usually seen at a high perch or just above the canopy. They are less common at lower levels, except when feeding at hummingbird feeders. Females may resemble adult or immature males. She is green above; her abdomen is white; her throat white-scaled green or blue. The feathers under her tail surrounding the vent are white-scaled dark blue. Her plumage varies greatly and identification can be confusing. However, her vent coloration is distinctive and not shared by similar species.
