White-crested Elaenia

Gray finch-like bird known from only a few sites in the Andes of northern Peru, including steep slopes above the Marañon Valley. Adult has bright yellow bill and legs, black mask, and white outer tail feathers that are hard to see when perched. Young birds have less black on the face and duller bill and legs. Inhabits arid regions with dense, scrubby forest. Forages mainly on the ground, but perches up higher to sing. Typical song is a rising, tremulous whistle.

Small green hummingbird found in a variety of open and semiopen habitats, such as forest edges, deserts, savannas, and gardens. Visits feeders. Iridescent green body with a forked dark blue tail and dark wings. Males have a black-tipped red bill with a blue throat, while females have a white belly, black mask, and a black bill with a red base.

Medium-sized pigeon with olive-green wings and a pale belly. Both sexes green overall with yellowish-green heads (brighter in males). Males have a vivid maroon wing patch. Compare with smaller Whistling Green-Pigeon in Japan and Taiwan. The only regularly occurring green-pigeon in mainland East Asia. Generally uncommon in a wide range of forest and forest edge habitats, occasionally gathering in flocks on coastlines to drink salt water, presumably to aid digestion of fruit. Gives a series of somewhat jumbled mellow cooing whistles, often introduced with two to three ascending notes and followed with undulating repeated coos.
