Diamantina Tapaculo
Scytalopus diamantinensis
Gray tapaculo with a black-barred buff vent. Females are browner above. Has a very small range, where it inhabits forests with dense understory at high elevations. The simple song consists of a single “chik” note repeated for long periods.
Identification
The Diamantina tapaculo is approximately 10 to 11 cm (3.9 to 4.3 in) long and weighs approximately 15 g (0.53 oz). The adult's plumage is identical to that of the Planalto tapaculo. The male's upperparts are mainly dark gray and the underparts paler gray. The flanks are buff with dark bars, which differentiate it from the similar but unbarred mouse-colored tapaculo. The female is browner.
Taxonomy
The Diamantina tapaculo was described as a new species in 2007. At that time it was thought to be closely related to the Planalto tapaculo (Scytalopus pachecoi), and the South American Classification Committee of the American Ornithological Society (AOS) and the Clements taxonomy have agreed. However, the International Ornithological Congress (IOC) has not accepted that placement.

Range and habitat
The Diamantina tapaculo is found only in the Chapada Diamantina in Brazil's Bahia state. It inhabits some of the remaining patches of dense forest in a region otherwise characterized by campo rupestre, a biome of grassland and rocky outcrops. In elevation it ranges from 850 to 1,600 m (2,790 to 5,250 ft).

Behavior
No information has been published about the Diamantina tapaculo's diet or foraging phenology.<p>Virtually nothing is known about the Diamantina tapaculo's breeding behavior. One nest has been described; it was a bowl of grasses in a rock crevice. The two nestlings were fed by both adults.<p>The Diamantina tapaculo's song is a simple note, quickly repeated, often for more than a minute [1]. Its call is unique, described as "a single 'tcheep' note".

Short-billed Gull
Larus brachyrhynchus
Small dainty gull. Dark-eyed and long-winged with a rounded head. Breeding adults are white-headed with an unmarked bill; non-breeding adults are smudged on the head and bill. Younger birds are brownish, with black-tipped pink bills. Occurs in western North America, primarily breeding in Alaska and Canada and wintering to Baja. Breeds in wetlands, meadows, and beaches; winters in waterside habitats and fields. Does not frequent large urban centers as much as some other gulls.

Tawny-crowned Greenlet
Tunchiornis ochraceiceps
Small, often rather active little bird of shady forest understory in humid tropical lowlands; often in areas with understory palms. Usually in pairs at middle levels moving with mixed-species flocks that often include Golden-crowned Warbler and Red-crowned Ant-Tanager. Rather drab brownish overall with tawny bushy crest, paler gray face and throat, and piercing pale eye (can be hard to see in the shade). Often gives a twangy, nasal “dwoi-dwoi-dwoi” call and a high, insectlike, whining whistle.

Russet-bellied Spinetail
Synallaxis zimmeri
Uncommon and endangered spinetail with a very small range in the western Andes of Peru. It has a gray head and back, a pale throat, buffy-chestnut lower underparts, a broken white eye-ring, and a long, rusty-edged tail. Inhabits dry to semi-humid scrub and forest. Vocalizations include a slow series of squeaks, sometimes preceded by a chuckling sound, and a much faster rattle.
