ermitaño de Natterer

The cinnamon-throated hermit is about 10 cm (3.9 in) long and weighs 2.3 to 3 g (0.08 to 0.11 oz). Males have brownish upperparts, green wings, and tawny underparts. Their inner pair of tail feathers are long and white tipped. Both sexes have a black "mask" with a pale supercilium and malar stripe. Females are similar to the male but with a paler throat and longer central tail feathers.

The cinnamon-throated hermit is known from two separate areas. One includes eastern Bolivia and the adjacent Brazilian states of Mato Grosso and Rondônia. The other is in northeastern Brazil, mostly in the states of Maranhão, Piauí, and Ceará, and in Pará and Tocantins as well. It is speculated to also inhabit the broad region between the two known areas. The proposed "Maranhao" hermit is found in the northeastern area. The species inhabits several non-rainforest landscapes including semi-deciduous, secondary, and gallery forests, cerrado, and caatinga. In elevation it ranges from sea level to 500 m (1,600 ft).

The cinnamon-throated hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of flowering plants for nectar. It also consumes small arthropods.
