Rufous-capped Nunlet

The rufous-capped nunlet (Nonnula ruficapilla) is a species of near-passerine bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found in Bolivia, Brazil, and Peru. == Taxonomy and systematics == These four subspecies of rufous-capped nunlet are generally recognized: N. r. rufipectus Chapman (1928) N. r. ruficapilla Tschudi (1844) N. r. inundata Novaes (1991) N. r. nattereri Hellmayr (1921) The grey-cheeked nunlet (N. frontalis) and brown nunlet (N. brunnea) have sometimes been suggested to be conspecific with the rufous-capped nunlet. Alternatively, one subspecies grey-capped nunlet, N. f. pallescens, has been suggested to instead be a subspecies of rufous-capped nunlet. The rufous-capped, grey-cheeked, and chestnut-headed (N. amaurocephala) nunlets form a superspecies. == Description == The rufous-capped nunlet is about 14 cm (5.5 in) long and weighs 14 to 22 g (0.49 to 0.78 oz). The nominate subspecies has a large rich chestnut crown. The rest of the face, its nape, and the sides of the breast are cold gray. The rest of the upperparts are plain dull brown with some reddish highlights. The chin and breast are reddish orange, the flanks a paler rufous, and the central underparts whitish. The bill is mostly silvery blue, the eye brown…
