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…

Spot-crowned Antvireo (Dysithamnus puncticeps) - male

The Spot-crowned Antvireo (Dysithamnus puncticeps) is a species in the antbirds family Thamnophilidae. It is found in Colombia, Costa Rica, Ecuador, and Panama. Its natural habitat is subtropical or tropical moist lowland forests, and found in lower levels, occasionally with mixed species flocks.  In Panama, it's uncommon on entire Caribbean slope and in the Pacific slope from eastern Panama Province eatward.

Spot-crowned Antvireo (Dysithamnus puncticeps) feeds largely on arthropods gathered by gleaning or with short sallies

It is the only antvireo with a streaked crown and pale eye, which are present in both sexes. It occurs in evergreen forest in lowlands and foothills, generally at lower elevations than the sympatric Plain Antvireo (D. mentalis). It inhabits the understory and is easiest to detect by checking through mixed flocks or listening through its song, a loud, fast, accelerating series of whistles.
