White-bellied Tanager
Tangara brasiliensis
Endemic to southeastern Brazil. 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. White belly. The call is a series of high-pitched “psii” notes.

Adult birds are 14 cm (5.5 in) long. 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. It differs from the turquoise tanager in that it is larger, has an overall more silvery blue plumage, blue edging to the primaries and a white belly.

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 brasiliensis. His description was based on Mathurin Jacques Brisson's Le tangara blue de Brésil that Brisson had described and illustrated in 1760. The type locality is Rio de Janeiro. The white-bellied tanager is now placed in the genus Tangara that was introduced by Brisson.<p>The white-bellied tanager was formerly treated as a subspecies of the turquoise tanager (Tangara mexicana).

Shelley's Rufous Sparrow
Passer shelleyi
A typical sparrow with a striped back, a gray crown and nape, and a black bib. The rufous rump is conspicuous in flight. The sexes are similar, though males are brighter overall and have more rufous on the face. Found locally in dry thorn savanna and cultivated areas, sometimes around human habitation. Similar to Somali Sparrow, but the male is separated by his gray crown and the female by her much more colorful overall plumage. Very similar to Kenya Rufous Sparrow, but not known to overlap in range, and Shelley’s is separated by its dark eye. The call is a cheerful “chirp” like that of other sparrows.
Gray-backed Tern
Onychoprion lunatus
A medium-sized tern of the tropical Pacific. Similar to Sooty Tern, but the back is gray (not black) and the white patch on the forehead extends behind the eye. Note deeply forked tail. Nests on the ground and occasionally on ledges on tropical islands. Rarely seen from shore.
Brown Cacholote
Pseudoseisura lophotes
Large ovenbird with rusty-brown plumage, a long crest, and piercing yellow eyes. Found in deciduous forest, second growth, and open woodland. Often also encountered in wooded urban areas like gardens and parks, where it mostly forages on the ground. The song is usually given as an unmusical duet.
