Marquesan Swiftlet
Aerodramus ocistus
A medium-sized swiftlet with a relatively long forked tail. Mostly brown with very slightly paler brown underparts and a more golden-brown rump and collar. Most common over rocky riverine valleys and humid forests. Similar to Atiu Swiftlet but is less contrastingly patterned, overall more uniformly brown, with a paler rump and a proportionally longer tail. Also extremely similar to Polynesian Swiftlet, but appears darker-faced and more obviously golden-collared. Vocally similar to Polynesian Swiftlet, with a voice consisting of insect-like buzzing and trilling.

Puna Ibis
Plegadis ridgwayi
Rather stocky, all-dark ibis of wetlands and lakes in high Andes; also wanders to coastal lowlands, where can be locally numerous. Usually in small groups. Feeds by probing with its downcurved bill. Breeding adult has dark chestnut head and neck, and red face. Nonbreeding and immature have whitish streaking on head and neck, and duller face. In flight, feet project only a short distance beyond tail tip. Compare with more slender and long-legged White-faced Ibis, but no range overlap.
Plumbeous-backed Thrush
Turdus reevei
A distinctive thrush restricted to dry forest in western Ecuador and northwestern Peru. Combination of bluish-gray upperparts, pale underparts washed with sandy buff, and white eye is unique in its range. Juvenile is profusely spotted on underparts. Generally stays high in the trees, where it can be quite easy to see. Often gives a whistled “fwee?” in addition to its beautiful song.
Black-billed Barbet
Lybius guifsobalito
A medium-sized black barbet with a mostly red head. With a good look, pale edges to the wing feathers are visible. Found at middle elevations in woodland, scrub, and cultivated areas, usually in pairs or small groups. Similar to Red-faced Barbet, but ranges don’t overlap, and Black-billed is easily separated by much more extensive red on the head. The vocalizations include a low growling and an explosive series of two-syllabled “KOOP-pup” phrases.
