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.

Japanese Sparrowhawk
Tachyspiza gularis
Typical Accipiter hawk. Adult slaty gray above and finely barred with brownish orange below. Smaller and more compact-looking than Eurasian Sparrowhawk. Soaring adults can be distinguished from Chinese Sparrowhawk by the lack of dark wingtips and striped (instead of solidly pale) underwings. In all plumages, heavily marked underwing coverts distinguish this species from Chinese Sparrowhawk. Breeds in a variety of forested hill and lowland habitats; wintering birds can also be found in more open habitats, such as forest edge and fields.
Sooty Flycatcher
Artomyias fuliginosa
Unusual small, chunky flycatcher. At a distance looks entirely dark, but a good view reveals a chocolate brown base color and paler brown streaking on the underparts. Has long, pointed wings and looks like a bit like a swallow in flight. Found in rainforest, where it perches up on dead trees, especially at the forest edge and around clearings. Often in small groups. Not very vocal, but does give a quiet, variable song of squeaks, whistles, and trills. Easily separated from other flycatchers by very dark plumage and unusual habits.
Tufted Titmouse
Baeolophus bicolor
Common backyard bird in the eastern U.S. Look for its overall gray plumage with paler underparts and orangey sides. Crest is gray, but forehead is black. Often in flocks with chickadees and other songbirds. Listen for clear, whistled "peter-peter-peter." Visits feeders.
