Black-nest Swiftlet

Scarce, yellow-faced woodpecker of lowland and foothill rainforest in western Colombia and northwestern Ecuador. Both sexes have olive upperparts, strongly barred or scaled underparts, and red wing patch. Male has red crown and mustache stripe; female has little or no red on head. No overlap with the similar White-throated Woodpecker. Forages at middle to upper levels of the forest, sometimes with mixed-species flocks. Call is a harsh scream.

Small, slender, and long-tailed bird found in dry caatinga scrub in eastern Brazil. It has grayish brown upperparts, buffy-yellow underparts and eyebrow, and conspicuous white patches in the wings and tail. Very similar to Greater Wagtail-Tyrant, but slightly smaller and tends to have duller yellow underparts and browner upperparts. Even their voices are similar, with both species giving rollicking series of rattling trills, often as a duet. Bahia Wagtail-Tyrant’s song sounds less dry and buzzy and includes more clear, whistled notes. Recently split from Lesser Wagtail-Tyrant, which is restricted to river islands in the Amazon basin.

Widespread and often numerous; found at shallow lakes and lagoons from the high Andes to Patagonian steppe and even in coastal waters. Adult is distinctive: pale pink with a salmon-pink “bustle” and grayish legs with red feet and “knees.” Immature often obviously smaller than adult, but has longer bill “hook” than the smaller and shorter-legged James’s Flamingo. Chilean Flamingo lacks the clean-cut black triangle on closed wings seen on Andean Flamingo. Far-carrying calls can suggest honking of geese.
