Masked Yellowthroat
Geothlypis aequinoctialis
Skulking warbler of grassy areas such as overgrown fields and marshes. Male has a striking black bandit mask, and his gray crown helps to separate him from other yellowthroats in range. Female is plain and confusing; she is yellower on the belly than female Common Yellowthroat, and tends to have darker upperparts than Olive-crowned Yellowthroat. Female also similar to female Yellow Warbler, but has a thicker bill and darker back. Song is a rather variable series of sweet whistles; also give a short, descending churr. Pairs usually stay hidden in dense vegetation. Males occasionally come up to sing or call from a more exposed perch. Note its range; after a taxonomical update, this species ranges only in northern South America.

Northern White-faced Owl
Ptilopsis leucotis
A relatively small owl, though larger than most scops-owls. Mostly pale gray, with a white face set off by black borders and yellow-orange eyes. Found in dry savanna habitats, where it often spends the day roosting on surprisingly open perches. Very similar to Southern White-faced Owl and best separated by call, but there is little or no overlap in range. The call is a quiet, two-parted “huu-hoooo.”
Ochre-bellied Flycatcher
Mionectes oleagineus
Rather plain, inconspicuous small flycatcher of humid tropical forest; also wanders into adjacent clearings and semiopen areas with fruiting bushes and trees. Usually found singly at lower to middle levels in shady understory and at times with mixed-species feeding flocks. Feeds mainly on fruit, plucked by short sallies. Plain olive plumage with ochre belly is distinctive. Also has habit of lifting one wing at a time and moving head slowly back and forth.
Chestnut-winged Foliage-gleaner
Dendroma erythroptera
Gray-brown foliage-gleaner with reddish wings and tail. Face and throat washed with dull yellow, with a faint eyeline; this is unlike many other foliage-gleaners which have a clear eyebrow or throat patch. Usually forages fairly high in the midstory and canopy of mature rainforest, often with mixed species flocks. Many foliage-gleaners have reddish wings; look for reddish wings contrasting with grayish body and tawny ochraceous face and throat in this species.
