Hartert's Leaf Warbler
Phylloscopus goodsoni
Bright yellowish leaf warbler of forest canopy. Like Blyth’s and Claudia’s leaf warblers, Hartert’s has the habit of flicking its wings alternately; compare to Kloss’s and Davison’s leaf warblers, which flick both wings at the same time. Bright olive above with a broad yellow brow and yellow-suffused white belly. Crown stripe and broad, orange-based bill distinguish this species from the similarly sized and shaped Arctic Warbler and Pale-legged Leaf Warbler. Breeds in foothill and submontane broadleaf forests, winters in various wooded habitats at lower elevations, including forest edge. Song is a sweet, high-pitched “wit-wichichew-wichichew-wichichew.” Call is a quiet “wit” or “wichichew.”

Monte Yellow-Finch
Sicalis mendozae
Small yellow terrestrial finch-like tanager of the Monte desert of central Argentina. Distinguished from most other Yellow-finches by its uniform bright yellow underparts, and from Saffron Finch by Monte Yellow-Finch’s larger bill and lack of orange in forecrown.
Variable Sunbird
Cinnyris venustus
Medium-sized sunbird with strikingly different breeding male and female plumages. Breeding males are green on the head and back, with a purple band across the breast. There is much regional variation; the belly can be yellow-orange, yellow, or white, though it is yellow across most of the range. Some subspecies also show extensive purple onto the throat. Females and non-breeding males are plain olive-brown on the back and dull yellow below. Found in a broad range of habitats, from arid thornscrub to moist savanna, gardens, and forest edge. Vocalizations typical of a sunbird, and include a quick jumbled song. Similar to Collared Sunbird, but larger, with a longer and more curved bill.
Northern Chestnut-breasted Wren
Cyphorhinus dichrous
Found at higher elevations than other members of its genus. Shy and uncommon denizen of forest undergrowth from 1,100–2,000 m. Chunky and short-tailed, dark brown above with rich rufous neck and breast. Blue eyering. Sexes alike. Could recall an antbird, but especially note pointier bill with a thicker base. Typically found in pairs or small family groups foraging on or near the ground. More easily heard than seen: listen for repeated sets of 2–3 eerie whistled notes stepping up in pitch, with little to no break between each set.
