Lilac-tailed Parrotlet
Touit batavicus
Small parrot of rainforest regions. Generally uncommon; distinctive black-and green plumage and purple tail render it unmistakable on the rare occasions it is seen well. Often first detected high overhead in large flocks that may bypass observers entirely, or else descend into forest canopy to feed quietly on flowers and fruit. Flight call is a strident, purring squeal.

分类信息
The lilac-tailed parrotlet was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Psittaca batavica in his catalogue of the Planches Enluminées. Buffon believed that his specimen had come from Batavia (modern Jakarta) but the German ornithologist Hans von Berlepsch realised this was an error and in 1908 substituted Venezuela as the type locality. The lilac-tailed parrotlet is now placed in the genus Touit that was introduced by the English zoologist George Robert Gray in 1855. The genus name is derived from the extinct Tupi language that was spoken by native people in Brazil: Tuí eté means "really little parrot".<p>The lilac-tailed parrotlet is monotypic.

分布与栖息地
The violet-tailed parrotlet is found discontinuously across northern South America. The regions include Colombia's Sierra Nevada de Santa Marta, two coastal areas in Venezuela, the island of Trinidad, and a broad swath from eastern Venezuela through Guyana and Suriname and across much of French Guiana. In most of its range it inhabits lowland deciduous forest but in Colombia and the Venezuelan Coastal Range it occurs in cloudforest between 700 and 1,700 m (2,300 and 5,600 ft). It uses both pristine and disturbed primary and secondary forest.

行为
The violet-tailed parrotlet is non-migratory but appears to be somewhat nomadic.<p>The violet-tailed parrotlet does most of its foraging in the morning. Its diet includes flowers, nectar, buds, berries, seeds, and fruits.<p>The violet-tailed parrotlet's breeding season has not been determined. Fledglings have been noter in December in Suriname and between January and March on Trinidad. The species nests in a cavity such as a hollow limb or one it excavates in an arboreal termite nest. The clutch size is five or six eggs. The incubation period, time to fledging, and details of parental care are not known.<p>The violet-tailed parrotlet's most common calls are "a slightly nasal “ryee” or “nee-ryee”." Large flocks in flight make "a continuous, monotonous, noisy chattering." It also makes "a very nasal “naaee” or “rrhaaee”" when perched.

Forest Penduline-Tit
Anthoscopus flavifrons
Tiny, drab bird with a sharp bill, a dull olive-green back, and buffy yellow underparts and forehead. Found in lowland rainforest, secondary forest, and sometimes plantations, usually in the canopy. Uncommon and inconspicuous, in pairs or small flocks. Similar to Yellow Penduline-Tit, but much duller and found in different habitat. Could be confused with Tit-Hylia, but duller overall, without streaking on the head and breast. Could also be confused with some dull sunbirds, but has a shorter, deeper-based, and sharper bill. The vocalizations are very high-pitched “sit” notes that are easily missed.
Chestnut Quail-thrush
Cinclosoma castanotum
Heavily patterned terrestrial bird of eastern South Australia, northwestern Victoria, and western New South Wales. White eyebrow and moustache, with a deep chestnut-brown back and intricately patterned wing. Female has white belly and gray chest, male white belly, gray flanks, and black chest and throat. Note gray sides rather than warm brown sides of Cinnamon and Chestnut-breasted quail-thrushes. Usually seen walking around in areas of open mallee woodland and shrubland. Call a long, high-pitched whistled "seeeep."
Pigeon Guillemot
Cepphus columba
Small jet-black seabird of coastal areas of the Pacific. Breeding plumage is black with bold white wing patch and bright red legs. Plumage changes dramatically in winter to whitish overall with dusky markings on body and black wingtips. Often found in shallower coastal waters than other alcids and regularly seen from shore. Dives to hunt for fish and invertebrates. Nests in crevice or burrow in a cliff or around large rocks.
