Scale-throated hermit
The scale-throated hermit is a species in the hummingbird family, Trochilidae.
It is found in the Atlantic forest in north-eastern Argentina, south-eastern Brazil, and eastern Paraguay. It is generally fairly common, and consequently considered to be of least concern by BirdLife International and IUCN.
The supposed "black-billed hermit", described as P. nigrirostris, has turned out to be a mutant P. eurynome with an all-black bill.Footnotes
