Plain Parakeet
Brotogeris tirica
Small and uniformly green parakeet with a long pointed tail and a pinkish bill and feet. In flight, the blue outer wing feathers and tail tips are visible. Usually seen in noisy groups foraging in a variety of habitats including the canopy and edge of humid forests, plantations, and agricultural landscapes. Common in and around cities.
识别特征
The plain parakeet is 23 to 25 cm (9.1 to 9.8 in) long and weighs about 63 g (2.2 oz). Adults have an essentially all green body, though their nape has a bluish tinge and their undersides have a yellowish one. Their shoulder is bronzy or brownish green and their flight feathers and the underside of their tail are bluish green. Their bill is pinkish with a paler base. Immature birds are similar to adults but with less blue in the wings and a shorter tail. The population in São Paulo state has many individuals with a blue mutation.
分类信息
The plain parakeet was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus tirica. The type locality was subsequently designated as Brazil. The plain parakeet is now placed with seven other parakeets in genus Brotogeris that was introduced in 1825 by Irish zoologist Nicholas Aylward Vigors. The genus name is from the Ancient Greek brotogērus meaning "with human voice". The specific epithet tirica is from the Tupi language tiriba meaning "tinkling". The word was used for a parakeet. The species is monotypic: no subspecies are recognized.

分布与栖息地
The plain parakeet is found in eastern Brazil from Alagoas south to Santa Catarina with an isolated population in Rio Grande do Sul. It inhabits the Atlantic Forest biome, where it occurs in secondary forest, cultivated land with groves of trees, plantations, and urban parks. It is common in cities "including the huge metropolises of Rio de Janeiro and São Paulo". Towards the higher elevations inland it also is found in the edges and canopy of montane rainforest. In elevation it is mostly in the lowlands but can be found as high as 1,200 m (3,900 ft).

Pycroft's Petrel
Pterodroma pycrofti
Small gadfly petrel. Gray upperparts and head, with darker “M” across wings. Underside white, with thin dark wing edge leading into a short diagonal bar cutting into the underwing. Main colonies breed on Mercury, Hen and Chickens, Poor Knights, and Ririwha Islands in New Zealand. Forages in warmer waters off the northern North Island. After breeding, migrates to the central North and Southwest Pacific. Cook’s Petrel is larger and paler but hard to differentiate at sea. Gould’s Petrel has a darker head, giving it a capped appearance, and more extensive dark on the underwing.
White-rumped Sirystes
Sirystes albocinereus
Distinctive black, gray, and white flycatcher of rainforest midstory and canopy. Medium-sized flycatcher with a small bushy crest; white underneath, gray above with a black head, wings, and tail. Found in mature rainforest and forest edges, especially around water. Its calls are quiet but make them much easier to find; listen for a musical “pew, pip.”
Yellow-throated Cuckoo
Chrysococcyx flavigularis
A small green-backed forest cuckoo of West and Central Africa. Males have a distinctive bright yellow throat and a brown-and-black barred belly, while females lack the yellow throat and have a brown-and-black barred face, throat, and breast. Can be located by its distinctive song, which is a series of up to 10 or more rapidly delivered clear whistles that speed up before quickly fading. Alternate call is an often overlooked “dwuit-tew” or “wait here.” Usually outnumbered by African Emerald Cuckoo, in which males have yellow bellies and green heads and females have more of a black-and-white barred appearance.
