Patagonian Canastero
Pseudasthenes patagonica
Drab canastero of central Argentina’s Monte desert region and northern Patagonian scrublands. Plain grayish-brown plumage and concolor tail distinctive in range. Song a very fast series of full, squeaked notes that slightly decellerates.
Identification
The Patagonian canastero is 14 to 15 cm (5.5 to 5.9 in) long and weighs 14 to 19 g (0.49 to 0.67 oz). The sexes have the same plumage. Adults have a light grayish brown face with hints of a paler supercilium and darker line behind the eye. Their crown and upperparts are light gray-brown. Their wings are somewhat browner and the feathers have somewhat rufescent edges. Their tail is dark gray-brown with chestnut on the outer feathers. Their chin and throat are grayish white with black flecks and streaks on the latter. Their breast is pale grayish, their upper belly pale buff-gray, their lower belly and flanks tawny, and their undertail coverts tawny-rufous.
Taxonomy
The Patagonian canastero was long placed in genus Asthenes. Beginning in 2010 it and three other members of Asthenes were moved to the newly coined genus Pseudasthenes. The Patagonian canastero is monotypic.

White-bellied Dacnis
Dacnis albiventris
Small, handsome tanager with piercing yellow eyes. Males are mostly cobalt-blue with a white belly and a black mask. Note the black feathers on the back and the blue-edged wings. Females are greenish-olive. Rare; found in the canopy and edges of humid forest on poor-quality soils, where it forages acrobatically and sometimes accompanies mixed-species tanager flocks. The similar male of the more common Black-faced Dacnis has darker blue plumage and a black mask that extends to the nape, while females are browner above and paler below.
Junin Tapaculo
Scytalopus gettyae
Poorly known Peruvian endemic found only in high Andean cloud forest northeast of the city of Huancayo. It was described to science in 2013. Adult male is plain gray, lacking the rufous barring on the lower underparts shown by Rufous-vented Tapaculo and Trilling Tapaculo. Female plumage not yet known with certainty. Younger birds are heavily marked with bars or scales. Best identified by range and voice. Typical song is a lengthy series that starts out with simple notes and gradually transitions into sputtering bursts.
Yellow-bellied Wattle-eye
Platysteira concreta
Small, distinctive, brightly colored wattle-eye. Both sexes show green or blue eye wattles and a greenish-gray back. The pattern on the underparts varies geographically: in males, either yellow or chestnut; and in females, either yellow with a diffuse chestnut throat or yellow with a well-defined diamond of chestnut on the throat. Found in thick parts of the understory of humid forest. Generally uncommon and shy. The vocalizations include high whistles, rising “wheet” notes, and lower rasping notes, often given in sequence.
