Rüppell's Bustard
Heterotetrax rueppelii
Small, pale, desert-dwelling bustard. Males have a bolder pattern of black, gray, and white on the face, though both sexes show a black stripe down the throat. Found in open desert and semi-desert, both in grassy areas and virtually barren gravel or sand flats. Usually in pairs. Call is a weirdly frog-like duet. Overlaps slightly with Karoo Bustard in southern Namibia, but easily separated by bolder face pattern and black stripe down the neck.

Mistletoe Tyrannulet
Zimmerius parvus
Small, drab tyrannulet found in the lowlands from eastern Guatemala and Belize south to extreme northwestern Colombia. Fairly inconspicuous; usually found as singles or pairs in middle to upper levels of forests, plantations, and second-growth. Typically perches fairly horizontally with the tail held slightly cocked. Feeds mainly on berries. Note the dull whitish eyebrow, small bill, and bright yellow edging on wing feathers.
Short-billed Canastero
Asthenes baeri
Medium-sized, rather nondescript bird, plain dull brown with a tail that is usually held cocked. Note the orange throat patch. Inhabits arid areas with scrub and woodlands, where it forages both in trees and on the ground. The song is a high nasal trill. The similar Sharp-billed Canastero has a longer bill and tail and an indistinct eyebrow.
Amethyst-throated Mountain-gem
Lampornis amethystinus
Rather large hummingbird of humid evergreen and pine-oak forest in mountains. Fairly common, but typically inconspicuous in shady understory and at edges, where feeds at all levels on flowers. Despite the exciting name, often looks rather drab and grayish overall with a dark mask, whitish eyestripe, and dusky throat (amethyst gorget rarely catches the light). Note the blackish tail with small, pale gray corners.
