Sulphur-bellied Tyrannulet
Mecocerculus minor
This uncommon tyrannulet is found in the Andes from extreme western Venezuela to Peru. Look for a combination of yellow underparts, white eyebrow, gray crown, and buffy wingbars. Like other members of its genus, tends to perch horizontally, which helps separate it from similarly-plumaged bristle-tyrants. Singles or pairs forage with mixed-species flock, usually in the canopy or subcanopy. Occurs in subtropical forests and edges from around 1,600 to 2,800 m. Listen for squeaky series of “chew” notes.

Pink-breasted Lark
Calendulauda poecilosterna
An unusual lark with a slim bill and pinkish-brown markings on the face and underparts. Unlike many larks, shows no white in the outer tail or rufous in the wing in flight. Found in dry savanna. More likely to be confused with a pipit than other larks, but separated by the pinkish plumage. The song is usually given from the top of a bush, and often repeated: a simple, tinkling series of high notes that accelerates and drops in pitch.
Long-billed Partridge
Rhizothera longirostris
Strange-looking and little-known partridge with a distinctive, faintly-hooked, dark bill. Male has a brownish-orange head and gray neck and chest. Female has a rusty-brown head and neck. Found in lowland and foothill forest; generally uncommon and patchy throughout range. Secretive, foraging quietly on the forest floor, rarely emerging into the open. Gives a loud, echoing “weeweew”.
Black-vented Shearwater
Puffinus opisthomelas
Small brown-and-white shearwater with messy appearance. Especially note smudgy face and neck. Found in warmer ocean waters off the west coast of North America, often close to land. Found singly or in small flocks, sometimes with other shearwaters. Most similar to Manx Shearwater but ranges do not usually overlap; also look for smudgier head, longer bill, and darker undertail coverts on Black-vented. Also compare with much larger Pink-footed Shearwater.
