Olivaceous Schiffornis

The Guianan schiffornis is 15.5 to 16.5 cm (6.1 to 6.5 in) long and weighs 28 to 37 g (0.99 to 1.3 oz). The sexes have the same plumage. Adults have an indistinct pale ring around the eye on an otherwise brownish olive face. Their upperparts and tail are brownish olive. Their wings are slightly browner. Their throat and breast are brownish and their belly and vent grayish olive. They have a dark iris.

The Guianan schiffornis is found from Bolívar and Delta Amacuro states in eastern Venezuela east through the Guianas and northern Brazil; in the last it is found north of the Amazon from the lower Negro River to the Atlantic in Amapá. It primarily inhabits the interior of humid and wet forest; it also is found, though rarely, at the forest edge and in mature secondary forest. It is mostly a bird of the lowlands but has been heard at about 1,450 m (4,800 ft) in the Sierra de Lema in Bolívar.

The Guianan schiffornis feeds on fruits and insects, though details are lacking. It usually forages singly and only rarely joins mixed-species feeding flocks. It forages mostly in the forests's understory, often clinging to a low-level vertical stem, and takes food from vegetation with short sallies from a perch.
