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).

Yellow-bellied Flycatcher
Empidonax flaviventris
Small flycatcher, extremely similar to several other species. Generally shy and inconspicuous; breeds in spruce forests often near boggy areas. Migrants tend to be found in denser wet areas within woods. Olive-greenish above with distinctive yellow wash on throat and belly. Black wings with bold white wingbars. Nearly identical to Western Flycatchers, but limited range overlap. Within range, main confusion species is Least Flycatcher. Bright yellow throat and belly is usually enough to identify Yellow-bellied Flycatcher, but some worn birds can be very similar. Song is similar to Least Flycatcher ("chebek") but more slurred, with a soft buzzy tone. Not frequently repeated like Least Flycatcher. Soft whistled call note, "pwee," unlike Least's sharp "whit" call.
Rufous Songlark
Cincloramphus mathewsi
Plain brownish songbird with faint pale eyebrow and rust-colored rump. Similar female White-winged Triller has white-edged wing panel. Brown Songlark larger, with longer legs and bill and more strongly patterned upperparts. Found across much of Australia, less so in the southeast, in treeless open habitats. Spectacular song includes long sequences of trills and loud electrical phrases, very unlike Brown Songlark.
Chestnut-capped Puffbird
Bucco macrodactylus
Attractive small puffbird of lowland rainforest. White below, reddish brown above, with a black mask and single black breast band. As with most puffbirds, can be difficult to spot as it sits motionless on a perch for long periods of time; usually perches fairly low, in the under and midstory in dense vegetation. Prefers forest edges and other areas of dense secondary growth, especially around water.
