Tropeiro Seedeater
Sporophila beltoni
Plump seedeater with a thick yellow bill. Males are blue-gray with a paler vent and females are olive-brown. Found in tall grassland areas and open savanna near water. During the austral winter, migrates north to central Brazil.
识别特征
The adult male is distinguished from the plumbeous seedeater by its larger size and bluish (rather than plumbeous) grey plumage, and from that and other Sporophila seedeaters, by having a robust, bright yellow beak with an arched culmen, and by vocalisations that include unique call notes.

分布与栖息地
Tropeiro seedeaters breed in upland shrubby grasslands associated with the Araucaria forests of southern Brazil. They migrate northwards to spend the austral winter – the non-breeding season – in the Cerrado savannas of central Brazil. The range contains a narrow contact zone between the Tropeiro and plumbeous seedeaters, where the birds are segregated by habitat that contains little significant gene flow.

Northern Red Bishop
Euplectes franciscanus
A very small gregarious species of open habitats including agricultural areas and the edges of marshes; often found in flocks of tens to hundreds. Note the black face and crown, brown wings, and long reddish orange uppertail coverts (concealing black tail) of breeding male. Nonbreeding males and females distinguished from similar Black-winged Bishop by smaller size and bill and told from Yellow-crowned Bishop by buffier coloration and more limited streaking on chest. Song is a rapid jumble of squeaky, twittering, and churring notes. Its calls include a sharp “tsit” and “tzit.”

Red-pate Cisticola
Cisticola ruficeps
A small but strong-billed cisticola that is rich gray-brown on the back and pale below. The back is plain in breeding plumage and heavily streaked in the non-breeding season. Note the black band and pale tips across the end of the tail. Found locally in savanna and dry woodland. Very similar to Dorst’s Cisticola, and best distinguished by song, but has a brighter rufous cap and whiter underparts. Also similar to Foxy and Rufous Cisticolas, but larger, with a rufous cap that contrasts with the gray-brown back. Perches up to sing a brief squeaky warbled phrase, thin and high-pitched.

Mourning Collared-Dove
Streptopelia decipiens
A medium-sized mostly buff-brown”‘ringneck” dove with a rosy-mauve neck and breast, dusky gray head, and a uniquely yellow eye surrounded by red bare skin. In flight it has visible white in the outer tail. Frequents savanna and woodland, particularly alongside humans and in well-wooded areas. Produces a distinctive “Look AT me” song, as well as a variety of crooning throaty “craaaooow” calls. All similar ringneck-doves lack the yellow eye surrounded by red bare skin.
