Plumbeous Antvireo
Dysithamnus plumbeus
Chunky antbird with a slightly hooked bill and a short tail; larger-bodied than most antwrens. The male is slate gray with a black breast and white spotting on the wings. Males also have a concealed white patch on their back. The female is mostly olive-brown with pale wing bars and throat. Inhabits the understory of humid forests where it occasionally follows mixed-species flocks. The song is a loud series of descending melancholic whistles.
识别特征
The plumbeous antvireo is about 12 to 13 cm (4.7 to 5.1 in) long. Adult males have a dark gray head, upperparts, and tail with a hidden white patch between the scapulars. Their wings are black with white tips and edges on the coverts. Their underparts are a darker blackish gray than the upperparts. Adult females have an olive-brown head and upperparts with buff-white spots on the wing coverts. Their throat is very pale gray, their breast olive-brown, and their belly and crissum ochraceous.
分类信息
The plumbeous antvireo was originally described in genus Myiothera, which is no longer in use. It was eventually transferred to Dysithamnus but around 1970 was moved by at least one author to genus Thamnomanes. This treatment was not widely accepted and by the 1980s it was confirmed to belong in Dysithamnus.<p>The plumbeous antvireo and what is now the white-streaked antvireo (D. leucostictus) were for a time treated as conspecific; they were separated in the early 2000s. The plumbeous antvireo is monotypic.

分布与栖息地
The plumbeous antvireo is found locally in southeastern Brazil in an area roughly bounded by southern Bahia, eastern Minas Gerais, Espírito Santo, and northern Rio de Janeiro states. It is a bird of the Atlantic Forest, where it inhabits the understory of evergreen forest. It occurs almost exclusively in primary or slightly disturbed forest and favors overgrown openings such as those created by fallen trees. In elevation it mostly occurs below 600 m (2,000 ft) but is found as high as 900 m (3,000 ft).

Large-billed Seed-Finch
Sporophila crassirostris
As the name suggests, this seed-finch has a truly massive bill – much larger than any seedeater. Male is all black with a small white wing patch. Bill is pale whitish or silvery. Female is brown with a dark bill. Very similar to Great-billed Seed-Finch, which is slightly larger; thankfully there is limited range overlap. Occurs in lowlands, primarily in scrubby or grassy fields and marshes. Uncommon.
Yellow-browed Seedeater
Crithagra whytii
A chunky medium-sized seedeater, brown above and pale below with heavy streaking. Patches of yellow appear on several parts of the body, including the eyebrows, breast, and edges of the wing and tail feathers. Found locally along forest edges and in moist scrub and bracken. Can be similar to female or immature Yellow-crowned Canary but larger, heavier-billed, and more streaked below, with a different distribution of yellow. Also somewhat similar to Reichard’s Seedeater, but easily distinguished by the yellow markings. The song is a fast-paced and variable mix of twitters and whistles. The most common call is a rising whiny whistle.
Emperor Penguin
Aptenodytes forsteri
Truly a royal and commanding presence, this largest of the penguins is seldom seen away from Antarctica and its surrounding seas, though young birds do disperse beyond the pack ice. Immense size and unique coloration readily distinguish this species from most other penguins; King Penguin is similar in patterning, but is smaller, longer-billed, less bulky overall, and has brighter and more extensive orange markings on the head. Breeds in immense colonies on the ice, with males famously spending months tending to the egg. Gives impressive trumpeting cries, especially during courtship.
