A rare visitor from lower elevations, the male White-necked Jacobin is unmistakable with its white belly and tail. Females are a bit more cryptic. The speckled green underparts and white tail tips are shared with the female Green-crowned Brilliant, but that species has a white moustachial stripe and a straighter bill. Some young Andean Emeralds have speckling extending across their breast, but it is never as heavy as in the Jacobin and they usually have a pink base to the bill. The black and white scaling on the vent of the jacobin is a good field mark.
