Turquoise Tanager
Tangara mexicana
Fairly widespread across northern Amazonia. Striking tanager found in the canopy in forest, edges, plantations, and gardens. Mostly seen in pairs or small single-species groups. Depending on the light can look quite dark, but has a mostly blue head and breast with black on the crown and around the bill, and blue flanks with black spots. Upperparts are mostly black with some blue highlights. Yellow belly. The call is a series of fast and high-pitched “psii” notes.
识别特征
Adult turquoise tanagers are 14 cm (5.5 in) long and weigh 20 g. They are long-tailed and with a dark stout pointed bill. The adult is mainly dark blue and black, with turquoise edging to the primaries. Most races have yellow lower underparts, but this is paler, more cream in the nominate subspecies found in north-eastern South America. The Trinidadian race, T. m. vieiloti, has a darker blue head and breast and more vividly yellow underparts than the mainland taxa. Their song is a fast squeaky chatter tic-tic-tic-tic-tic.
分类信息
The turquoise tanager was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the 12th edition of his Systema Naturae under the binomial name Tanagra mexicana. His description was principally based on Mathurin Jacques Brisson's Le tangara blue de Cayenne that he had described and illustrated in 1760. The type locality is Cayenne in French Guiana. The turquoise tanager is now placed in the genus Tangara that was introduced by Brisson.<p>Four subspecies are recognised:<p>The white-bellied tanager (Tangara brasiliensis) was formerly treated as a subspecies.

White-eyed Parakeet
Psittacara leucophthalmus
Medium-sized parakeet, with a long graduated tail. Mostly green body with variable amounts of red spots on the head, neck, and shoulders. Has bare white eyerings and a pale bill. Often found in large noisy groups in a variety of habitats including forests, savanna, mangroves, and urban areas.
Kosrae White-eye
Zosterops cinereus
Small ash-gray warbler-like bird, endemic to the Micronesian island of Kosrae. Combination of uniform coloration, size, and pale eye-ring makes this species unique on the island. Forages in a range of wooded habitats, from mangroves to remnant native rainforest. Much like other white-eyes, often forages in active, fast-moving flocks, but can also be encountered singly or in pairs. Gives squeaky chirruping calls rather similar to those made by sparrows or small parakeets.
Ochre-naped Ground-Tyrant
Muscisaxicola flavinucha
Fairly large terrestrial flycatcher, breeding in the southern Andes and migrating north in winter. Favors bogs, streamsides, and other wet areas in open rocky and stony terrain, but migrants can be grounded in lowland fields. Often in same areas as other ground-tyrant species, and identified by grayish plumage tones, whitish forehead patch, and contrasting ochre nape patch (can be hard to see, depending on angle).
