Black-and-white Becard
Pachyramphus albogriseus
Small becard occurring from Venezuela to Peru, mainly on the east slope of the Andes, and disjunctly in Costa Rica and Panama. Mostly found in foothills, in middle to upper levels of humid montane forest. Male is mostly gray with bold white edges on the wing feathers and a black cap with pale spectacles. Compare with White-winged Becard, which has a black back and dark lores. Female is very different; look for her brown cap bordered with black, white spectacles, pale yellowish belly, and tawny edges on wing feathers. Extremely similar to Cryptic Becard, with potential range overlap on the east slope of the Andes in Ecuador and Peru. Male Black-and-white shows a broader upper wingbar, darker lores, a blacker upperside of the tail, and stouter bill than Cryptic. Female Black-and-white has a brighter rufous crown with a broader black border. These features may all be difficult or impossible to assess in the field; some birds are best left unidentified. Also note voice: song a slow series of one or several sweet downslurred whistles followed by an upslurred whistle, often repeated two or three times. Cryptic’s song is faster, with shorter notes.

Undulated Antshrike
Frederickena unduliger
Magnificent dark antshrike of mature upland rainforest. Has a large head with a crest and strongly hooked bill. Males are slaty gray with fine black barring; females are tawny orange with fine black barring. Larger than most other antshrikes and antbirds in its range. Forages singly or in pairs in open understory, and seems to be somewhat rare throughout its range. Its song is a gradually rising series of low whistles given at a steady pace.
Chestnut-winged Hookbill
Ancistrops strigilatus
Streaky canopy foliage-gleaner with a slightly hooked bill tip. Light buffy brown overall with extensive streaking from the head down to the back and breast, with reddish wings and tail. Forages in the midstory and canopy with mixed species flocks, keeping its body horizontal as it clambers along branches. Most common in upland forest, where it can be the most common foliage-gleaner in canopy mixed species flocks, but can also occasionally be found in mature forest in seasonally flooded areas.
Beautiful Woodpecker
Melanerpes pulcher
Medium-sized woodpecker endemic to northern Colombia. Strikingly patterned: black above and buffy below with bright red crown, yellow nape, black mask, barred flanks, and a white stripe down the back. Found in dry woodlands and edges, usually in pairs. Compare with Black-cheeked Woodpecker, which lacks a yellow nape and has white spots on the wings.
