Green-tailed Towhee

Huge bulky lark with a sharp, slightly decurved bill. Pale brown above and off-white below, with a pale brow stripe, distinct brownish ear patch, and a black mark on the neck near the shoulder. Has a less contrasting head pattern than Calandra Lark and Bimaculated Lark, but is overall more strongly patterned than female Black Lark. Distinctively blade-like bill also distinguishes this species from the former two. In flight, snowy white tail edges and back wing edges are eye-catchingly prominent; Calandra Lark has minimal white on the tail tips, and Bimaculated Lark lacks white on either wings or tail. Found in high plateau regions, where it prefers rather wet areas, often on the margins of lakes, marshes, and flooded pastures. Song, given in flight, includes rolling warbles and buzzy grating notes. Calls resemble harsh, buzzy phrases from song.       

Tiny, boldly-colored flycatcher. Compact and short-tailed; yellow below, black above, with a white throat and mustache, and small red shoulder patch. Found in secondary forest, especially with tall bamboo, in a limited range along the foothills of the Andes in southern Peru. Its chirping musical song is often duetted.

Gray, spotted piculet of mid-elevation forests. Dusky gray above and white below, with extensive black spotting from the head to the belly; males have a scarlet red forehead patch. Found at higher elevations than most other piculets in its range; grayer, with much more extensive black spotting, than the pale Fine-barred Piculet. Forages singly or in pairs in the mid-story of humid montane forest, sometimes joining mixed-species flocks. Its song is a very high, descending series of sharp, metallic notes.
