Canebrake Groundcreeper
Clibanornis dendrocolaptoides
Large, long-tailed ovenbird, rusty above and grayish below. Note the buff eyebrow and black spots at the sides of the throat. Found in montane forest and old second growth; often associated with bamboo or dense understory, usually near streams. Behavior poorly known, but forages in pairs both arboreally and terrestrially. Song is a loud series of staccato notes.
识别特征
The canebrake groundcreeper is 20 to 22 cm (7.9 to 8.7 in) long and weighs 52 to 54 g (1.8 to 1.9 oz). It is a largish furnariid with an almost straight bill. The sexes have the same plumage. Adults have a narrow grayish or buff-gray supercilium that widens to the rear and dark brown lores on an otherwise dull reddish brown face. Their crown is dark chestnut-brown, their back and rump rufescent brown, and their uppertail coverts rufous-brown. Their wing coverts and flight feathers are also rufous-brown. Their tail's central pair of feathers are dull rufous-brown and the rest rufous-chestnut. Their throat is white with blackish speckles on the sides, their breast and belly dull grayish, their sides rufous-brown, and their flanks and undertail coverts ochraceous brown.Their iris is brown, their bill black, and their legs and feet olive-green to greenish gray. Juveniles have a plain buff-washed white throat, faint buff mottling on the breast, and a grayer belly than the nominate.

分布与栖息地
The canebrake groundcreeper is found in southeastern Brazil from São Paulo state south into Rio Grande do Sul and in northeastern Argentina's Misiones Province. There are also fairly old records and reports of single birds in eastern Paraguay but apparently no permanent residents. It inhabits montane and tropical lowland evergreen forest, where it favors hilly terrain and the forest edge and secondary forest. It tends to be near watercourses and frequents bamboo thickets and dense understory along them. In elevation it ranges from near sea level to 1,200 m (3,900 ft).

Indian Yellow Tit
Machlolophus aplonotus
The only crested tit in most of its range. Black front with yellow cheek and yellow eyebrow. Yellowish-green upperparts, white-spotted wings, and yellow-and-black underparts. Females and juveniles are duller, with shorter crests, central stripe thinner and incomplete, and yellowish parts becoming dull white. A bird of the hills, it is most abundant between 500 meters and 1800 meters of elevation, but rarely descends to lower elevations. Seen in pairs or family groups, often joining mixed-species foraging flocks in the non-breeding season. Forages in the canopy, emitting loud whistles and harsh chatters.
Thick-billed Green-Pigeon
Treron curvirostra
Brightly-colored and thickset pigeon of the forest canopy, usually seen flying over in pairs or small groups. Distinctive bicolored bill and bright green eyering are visible even from a distance. Both sexes are mostly green. Males have maroon backs, while females are green all over; both have jagged bright yellow striping on the wing edges. Flocks are seen in fruiting trees in lowland and foothill forests, where they often associate with other green pigeons. Gives smoothly undulating “woooOOOO”, often in series.
Yellow-shouldered Blackbird
Agelaius xanthomus
An inhabitant of coastal mangroves and nearby scrublands. This species is all black, except for a bright yellow shoulder patch—a combination that eliminates all other species in its range. At times, the shoulder patch is hidden such that it can resemble the Shiny Cowbird. The Shiny Cowbird has glossier plumage and a shorter, thicker bill. Vocalizations include a rough “chet” or “chulp” and a braying “naaaaaaaah.”
