Mountain Leaf Warbler

Uncommon swallow in montane forest in the Andes from Venezuela to Bolivia. Similar to the more common Blue-and-white Swallow, but look for the buffy throat and browner flanks on Pale-footed Swallow. Found in flocks, usually not far from forest. Not frequently found around human settlements unlike Blue-and-white Swallow. Occurs from around 2,400–3,200 m.

A common, lovebird-sized parrot of wooded areas in the lowlands and foothills. Overall green in color with a darker back, darker wings with blue edges and black tips, and paler green underparts and rump. Male has a blue face and collar. Female has reduced blue on the face with a scaled collar and rump. Similar in length to Philippine Hanging-Parrot, but Guaiabero is shorter-tailed and stockier, with a black rather than red bill. Voice consists of high-pitched ringing notes, often given in pairs.

Small hummingbird with long, curved bill. Male dusky-greenish with contrasting white chest, expansive purple throat, and long forked tail (usually held closed in a point). Female is buffy below with a dusky mask and buffy eyebrow. All ages and sexes are most easily identified by bill shape. Found in deserts; shows a preference for flowering agave plants. Primarily a Mexican species, with very limited range in the U.S. Occurs to just south of Mexico City, where range limit with extremely similar Beautiful Hummingbird is not perfectly known. Male Lucifer has pointed outer tail feathers vs. blunt on Beautiful, but otherwise essentially inseparable.
