Grauwangen-Faulvogel

Bestimmung

The grey-cheeked nunlet is 14 to 15 cm (5.5 to 5.9 in) long and weighs 14.5 to 19.5 g (0.51 to 0.69 oz). The nominate subspecies has a very dark chestnut crown and plain brown upperparts, lighter on the rump. Most of the face is gray with a ring of bare red skin around the dark brown eye. The tail is dark brown and almost black near the tip. The chin, throat, breast, and flanks are rufous and the belly is buffy. The bill is mostly blue-gray and the feet dull brown or greenish gray. N. f. stulta has a very dark crown and its tail is blacker and rump drabber than those of the nominate. N. f. pallescens has much paler upperparts than the nominate and its throat and breast are buff.

Taxonomie

The grey-cheeked nunlet was first described by P.L. Sclater in 1854 in Colombia. Three subspecies are generally recognized, the nominate N. f. frontalis, N. f. stulta, and N. f. pallescens. The nominate has been suggested to constitute more than one taxon based on differences in coloration observed in specimens. N. f. pallescens has occasionally been suggested to be a subspecies of the rufous-capped nunlet (N. ruficapilla) of southern Amazonia. The grey-cheeked nunlet forms a superspecies with the rufous-capped nunlet and the chestnut-headed nunlet (N. amaurocephala), which is restricted to a small area in northwest Brazil. It has been suggested to be conspecific with the rufous-capped nunlet and also with the brown nunlet (N. brunnea).

Verbreitung und Lebensraum

The grey-cheeked nunlet has a somewhat restricted range that extends from central Panama to north-central Colombia. N. f. stulta is the northernmost subspecies; it is found from central Panama into extreme northwestern Colombia. N. f. pallescens is found in the Caribbean lowlands of northern Colombia. The nominate subspecies is found in the interior of northern Colombia. The species inhabits a variety of landscapes including moist to humid primary and secondary forest, gallery forest, and thickets; it especially favors woodlands along rivers. it usually inhabits the lower levels of the forest but can be found up to the subcanopy. In elevation it ranges from sea level to 1,000 m (3,300 ft).
