Black-winged Ground Dove
Metriopelia melanoptera
Rather plain, medium-sized dove of the Andes and foothills. Often fairly common on open grassy and stony slopes, at bogs, around animal corrals, and villages in agricultural areas. Usually in pairs or flocks, sometimes mixed with sierra finches and other seed-eating birds. Feeds on ground, but often perches on prominent rocks; flushes with a loud rattling wing whistle. Note diagnostic orange teardrop under eye and white “shoulder” flashes that show best in flight. Smaller than Eared Dove, without big black spots on wings.
识别特征
The black-winged ground dove is 21 to 23 cm (8.3 to 9.1 in) long. Males weigh 89.1 to 114 g (3.14 to 4.02 oz) and females 86 to 96.1 g (3.03 to 3.39 oz). The nominate adult male is grayish brown or earth brown above with a faint pink tinge. The throat is whitish and the underparts fawn pink with gray flanks. The closed wing shows a white edge and some pale gray. The eye color is highly variable as is the bare skin that surrounds it. The adult female's upperparts are a duller brown than the male's and the underparts less pink. Juveniles do not have the adults' pink tinge, and many feathers have buff edges. M. m. saturatior differs from the nominate by being darker and grayer above and less pink below.<p>The nominate subspecies of black-winged ground dove is a year-round resident from central Peru and adjacent Bolivia south through most of Chile and western Argentina. It breeds but does not winter on Tierra del Fuego. M. m. saturatior is found in the Andes of southwestern Colombia south to Ecuador's Azuay Province.<p>The black-winged ground dove inhabits páramo in Colombia and Ecuador and puna in Peru, Bolivia, Chile, and Argentina. It is typically found in grassy areas near treeline but roosts in Polylepis woodland and Puya stands. In much of its range it occurs between 2,000 and 4,400 m (6,600 and 14,400 ft) but from 900 to 4,900 m (3,000 to 16,100 ft) in Chile. It moves to the lower elevations in winter.

Lesser Adjutant
Leptoptilos javanicus
A large stork with a completely bare head and neck ideal for its scavenging habits. The adult’s face is red and the neck is yellow while the juvenile has a brownish head and a white, thinly-feathered neck. The upperparts are all dark while the underparts are mostly white. In flight, note the broad wings with distinctive white “armpits” and tucked in neck. Similar to the larger Greater Adjutant; Lesser has a more slender bill, has all-dark upperwings, and often adopts a more upright, less “hunched” posture. Often found in shallow marshes, fields, and swamps.
Violet-capped Woodnymph
Thalurania glaucopis
Common hummingbird of both montane and lowland forests and woodlands. Also visits feeders and gardens. Males have a metallic green body, dark wings, a long deeply forked blue tail and a violet crown. Females have a green crown and are pale gray below with a shorter tail.
Black Metaltail
Metallura phoebe
Unusually dark hummingbird endemic to the high Andes of Peru. Plumage is mostly black with subtle hints of red and green. The tail is coppery when seen in good light, and it has a small white spot behind the eye. Adult male has a glittering green throat patch, which is smaller in females and absent in immature birds. Inhabits dense scrub and short forest. Often gives high-pitched, piping squeaks, either alone or in a short, descending series.
