Red-rumped Bush-Tyrant

A lively inhabitant of most wooded habitats, coffee plantations, and gardens. The long-tailed male is distinctive in being entirely iridescent green, although can radiate blue at certain angles and lighting. Male Green-throated Carib and Green Mango can also appear entirely green, however both are larger, with longer and strongly curved bills. The female Puerto Rican Emerald is metallic green above, dingy white below, and has a relatively long, forked tail. Its face is typically blackish with a small white spot behind the eye. The similar Antillean Crested Hummingbird has a shorter bill, lacks the black in face and the spot behind the eye, and it has a rounded tail. The emerald's song is a rapid twittering and the common call is a high thin metallic "tsip" given singly or in series.​

A rather dull-plumaged songbird of fields, grasslands, forest edges, and farmland, mostly at moderate and high elevations. Often sparsely distributed and difficult to find. Gray-brown above with a pale belly and blackish streaking on head and wings. Breeding males become black-billed and darker on the face, losing the pale eyebrow that is usually shown in other plumages. Typically found singly or in pairs, clambering about in grasses and shrubbery. Often sings from an exposed perch, giving a loud but dry, rolling series of notes, slower than the song of Striped Prinia. Visually very similar to Striped Prinia, but usually separated by range. In the area of overlap, female and non-breeding male Himalayan Prinias show weaker streaking on the back and a duller rufous panel in the wings. Breeding males are distinguished by their darker faces without an eye-stripe. Also similar to Burmese Prinia, but there is little or no overlap in range, and Himalayan Prinia is distinguished by having more streaking, especially along the sides of the breast.

A small, compact finch-like sociable lark that is nomadic, and often irrupts in large numbers after good rains. The sexes differ in plumage: the distinctive male is mostly black, including under the wings, with chestnut-sprinkled upperparts; the female is reddish-brown above and streaked underneath. Small to medium-sized flocks (often mixed with Gray-backed Sparrow-Lark) can appear in grassy shrubland in the Karoo and Kalahari, where dark males are conspicuous when they fly up on broad wings and flap slowly in the fashion of a butterfly. They drop to the ground and land on bare patches, where they shuffle along foraging for seeds and insects. The female Black-eared Sparrow-Lark is told apart from other female sparrow-larks by its all-dark underwings in flight and the lack of a black belly patch.
