Gray Greenbul
Eurillas gracilis
A small, slender greenbul most often found near forest edge and in other disturbed and semi-disturbed habitats. Olive below, becoming more yellow toward the belly, and olive-green above, becoming grayer toward the head with noticeable white eye-arcs. Similar to other dully colored greenbuls, especially Ansorge’s Greenbul and Plain Greenbul, but note Gray Greenbul’s edge habitat preferences, yellowish belly, and distinctive song: a plaintive, halting “teach-er, who teach-es you?” that generally rises in pitch.

Northern Schiffornis
Schiffornis veraepacis
Elusive, chunky brown bird of shady forest understory in humid tropical lowlands. Heard far more often than seen. Haunting, slurred whistle carries well and is easily imitated. Song given irregularly; not steadily repeated. Note the chunky build, drab dark olive-brown plumage with paler eyering accentuating big eye, and rather slender black bill. Tends to perch quietly and upright, then slips off like a ghost and not seen again.
White-winged Grosbeak
Mycerobas carnipes
A brightly-colored finch usually found in hilly or montane coniferous and mixed forests. Male is black above and yellow below. Female is similar, but has a brownish-gray head and chest. Both sexes have white and yellow patches on the wings. Male resembles his Spot-winged Grosbeak counterpart, but White-winged has fewer white spots on the wing and a black (not yellow) chest. The female White-winged superficially resembles female Collared Grosbeak, but female White-winged has a white spot on the wings.
Marbled Duck
Marmaronetta angustirostris
Small, subtly beautiful, gray-brown duck with a black eye-mask, long neck and wings, and dark bill. Vaguely resembles a female pintail. Both sexes are similar but males sport a more prominent shaggy crest. In flight looks pallid, with whitish underwings, pale secondaries, and dark wingtips. Mostly silent. Typically found in shallow, freshwater or brackish wetlands with abundant emergent vegetation.
