Crested Quail-Dove
Geotrygon versicolor
A plump dove that inhabits dense, moist forests in foothills and mountains. Prefers dense leaf litter, but is sometimes found along trails and roadsides. Its namesake crest is short and swept back, so it is not always readily apparent. However, it can be told from Ruddy Quail-Dove by its larger size, mostly purple upperparts, gray underparts, and lack of a bold pale facial stripe. Song is deep “hoo-oo-hoo,” with emphasis on the middle segment.
识别特征
Male crested quail-doves are 27 to 31 cm (11 to 12 in) long; females are 27 to 30 cm (11 to 12 in). They weigh about 225 g (7.9 oz). Males have a black forehead and a drab brown crown. The nape is gray and has elongated feathers producing the eponymous crest. The back and sides of the neck are metallic bronze or bronze-green. The face is mostly gray with a broad reddish buff malar stripe. The gray continues to the belly; the belly and flanks are chestnut. The upper back and wing coverts are iridescent reddish purple, the mid-back bluish purple, and the lower back and tail greenish black with purple iridescence. The eye is red, surrounded by bare gray skin. Many females look the same as the male, but sometimes they are paler overall and browner on the neck and belly. Juveniles are duller than the adults and most feathers show rust-colored edges.
分类信息
At one time the crested quail-dove was the sole member of genus Geotrygon. Most of what are now the other species in the genus were previously in genus Oreopeleia, which was merged into Geotrygon. The crested quail-dove is monotypic.

Pink-browed Rosefinch
Carpodacus rodochroa
Graceful medium-sized rosefinch of the Himalayas. Male is bright raspberry pink with a clean “browed” facial pattern and faint streaking on the back. Female is brown with streaked buffy underparts, broad white eyebrows, and lightly streaked pale cheeks and throat. Favors subalpine forest edge and grassy hillsides with scrubby cover in the breeding season; descends in the winter, using similar habitat in the foothills. Gives a loud, insistent “teeLEE!”
Ayres's Hawk-Eagle
Hieraaetus ayresii
Small black-and-white eagle. Has a compact, powerful shape, and the hint of a crest. The upperparts are black, and there are heavy black markings on the underparts and evenly across the underwing. Found in thick woodland and forest. Soars frequently. Call is a loud, repeated “kwee-ya.” Similar to other hawk-eagles, but has more heavily marked underparts. Easily separated in flight, when Ayres’s Hawk-Eagle shows black barring across the entire underwing.
Turquoise Jay
Cyanolyca turcosa
Noisy and well-named jay of Andean cloud forest. Range is mostly confined to Ecuador, but it does reach adjacent areas of Colombia and Peru. Plumage is bright turquoise-blue with a black mask, black breast band, and whitish forecrown. Very similar to Black-collared Jay (limited range overlap), but brighter blue, especially on crown and throat. Told from Beautiful Jay by the breast band and lack of dark gray on back and breast. Small groups move conspicuously through the forest giving an impressive variety of calls, including screeches, churrs, and mews.
