Russet-winged Schiffornis (Schiffornis stenorhyncha)

Russet-winged Schiffornis is one of five species that formerly were united under the name Thrush-like Schiffornis (Schiffornis turdina); the other members of this group are Northern Schiffornis (S. veraepacis), Olivaceous Schiffornis (S. olivacea), Foothill Schiffornis (S. aenea), and Brown-winged Schiffornis (S. turdina). 

Russet-winged Schiffornis is a representative of this group that occurs from central Panama east across northern Colombia to western and northern Venezuela. All species in this group have similar, dull plumages, being primarily brown or olive brown, with paler underparts, and prominent large dark eyes. Although all members of the group also are poorly known, Russet-winged Schiffornis probably is one of the least studied members of the complex. This is a relatively low density species that occupies the understory of terra firme forests, most often foraging within 1-2 m of the ground, and typically is solitary. The clear whistled song is heard far more often than th…

This is a solitary breeder, not normally found in heron colonies. The nest is a small flattish stick platform in a tree into which 2–3 green-tinged white eggs are laid. In Panama it's common on Pacific islands including Coiba and Pearl Islands, and supposedly rare along mainland Pacific coast, but we usually find them in eastern Panam√° Province.
