The Cinnamon-throated Hermit (Phaethornis nattereri) is a species in the hummingbird family, Trochilidae. It is found in a broad dry to semi-humid belt along the southern edge of the Amazon Rainforest from far north-eastern Bolivia north-east to Maranhão in Brazil. Its natural habitat is tropical dry to semi-humid forest, Cerrado and woodland. With its wide range, it is considered a Species of Least Concern by the IUCN.
There is quite some confusion about the taxonomic status of birds called Maranhao Hermit. It is sometimes treated as a subspecies of the Cinnamon-throated Hermit, but at present most follow the analysis by Hinkelmann where it merely is considered the male plumage of P. nattereri. But as it seems, the Maranhao Hermit only occurs in the northern part of the range of P. nattereri, and as the two have different voices they seem to warrant recognition as distinct species P. maranhaoensis. Molecular work also confirms the validity as a separate species, though details presently are lacking.
