Puna Teal
Spatula puna
Handsome and distinctive dabbling duck of the high Andes. Note the black cap, bright pale creamy cheeks, and powder-blue bill. Like most South American dabbling ducks (but unlike most Northern Hemisphere species), sexes look similar year-round, although male on average is brighter and more boldly patterned. Often fairly common on bogs, lakes, and other wetlands, especially with reeds and other emergent vegetation. The smaller and duller Silver Teal occurs in lowlands, not the high Andes.
识别特征
The Puna teal is 19 inches (480 mm) long, similar in size to a wood duck. They have a black cap that extends to below the eyes. Their lower face and neck are creamy white. Their upper tail coverts are gray, and their rear flanks are dark brown with thin stripes. Back, chest and lower flanks are light coffee with dark brown spots. Their bill is large, light blue with a black line down the middle.
分类信息
The first formal description of the Puna teal was by the Swiss naturalist Johann Jakob von Tschudi in 1844 under the binomial name Anas puna. It was at one time considered as a subspecies of the silver teal in the genus Anas. A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus Anas, as then defined, was non-monophyletic. The genus was subsequently split into four monophyletic genera with ten species including the Puna teal moved into the resurrected genus Spatula. This genus had been originally proposed by the German zoologist Friedrich Boie in 1822. The name Spatula is the Latin for a "spoon" or "spatula". The specific epithet puna is from the Puna de Atacama, a plateau in the Andes.

行为
In the wild they live in small groups of their own kind or with the closely related silver teal. Puna teal lay their eggs between April and June. Like swans and geese both parents rear the ducklings. They lay their eggs in long grass, not always close to the water. The eggs are a creamy pink colour of which there may be several. The relationship between the male and female may be long term.

Barred Fruiteater
Pipreola arcuata
Chunky, short-tailed, flat-headed bird patterned in green and black. Male has black head and breast, pale yellow belly with bold dark barring, and mossy green upperparts with bold pale spotting on the wing. Female is similar but has a green head with barring all the way up the throat. On both sexes, note red bill and legs and pale eye varying from orange to gray to whitish. Fairly common in stunted forested habitats in the upper subtropical and temperate zone in the Andes. Sluggish; perches quietly in the middle levels of the forest, sometimes following a mixed-species flock. May be seen singly or in pairs, but several can gather around a fruiting tree. Listen for super high-pitched calls.

Black-headed Nightingale-Thrush
Catharus mexicanus
Small, plain-breasted thrush of tropical and subtropical evergreen forest in foothills and highlands. Usually elusive and heard far more often than seen. Feeds mainly on the ground, but also in fruiting bushes and trees. Sings from low to middle level perches. Plumage distinctive, with blackish cap, contrasting orange eyering and bill, and dusky upperparts. In dark shady understory, could be confused with Orange-billed Nightingale-Thrush, which has rusty brown upperparts. Song distinctive: slightly scratchy and not very fluty.

Pale-eyed Blackbird
Agelasticus xanthophthalmus
Medium-sized blackbird found locally in habitats with wet grass. Shiny black, with a white or light yellow eye and sharply pointed black bill. Giant Cowbird occasionally has a pale eye and may appear similar, but is much larger than Pale-eyed Blackbird; told apart from the similar Velvet-fronted Grackle by its pale eyes, longer, more pointed bill, and shorter tail. Found in wet grasslands and grassy margins of oxbow lakes, where it forages singly, in pairs, or in small groups.
