White-tailed Lark
Mirafra albicauda
A small, compact lark with blackish upperparts that appear very scaly in fresh plumage, a bold whitish eyebrow that starts in front of the eye, and a pale belly that contrasts strongly with blotchy blackish breast streaks. The stout bill is bicolored: pale below and dark on the tip and ridge of the upper mandible. Tail is mostly dark with bold white outer feathers that are conspicuous in flight. Resident in cropped grassland, mostly on black cotton soils, preferring lake edges. Somewhat furtive, preferring to dart into cover rather than parade in the open. Sings a rambling set of whistles, churrs, and chips in a protracted aerial display, lacking trills and with a simpler structure than Singing Bushlark. Other similar larks are less strongly contrasting, with more tawny-gray tones in the plumage.

Eastern Subalpine Warbler
Curruca cantillans
A small, slim warbler with a long tail. Breeding males are distinctive, with gray upperparts contrasting with a puffy rufous throat and breast, and a bold white moustache mark. Female and non-breeding males resemble a washed-out version of the breeding male, with much less rufous below. Typically found in scrubby, dense bushy habitats, but also in more open woodland and savanna. Sings from the tops of bushes, giving a rattling and loud sequence of notes. The calls are dry “trkk” or "trk-tek" notes, which are also incorporated into the song. Very similar to Moltoni’s Warbler, and best separated by the call (single or subtly doubled notes rather than dry rattles); breeding male is also richer rufous below. Also very similar to Western Subalpine Warbler, but call is subtly different: Eastern’s is slightly softer and tends to have two syllables. Breeding males are separated visually from Western by having more white on the belly, a darker face, and a broader white moustache.
Whooping Motmot
Momotus subrufescens
Large motmot of lowland forest and edges from eastern Panama to northwestern South America. Green above and warm rufous below, with a black mask bordered by a dazzling cerulean crown. The crown is not solidly blue, but instead has a circular black patch in the middle as if it’s wearing a yarmulke. Like most other motmots, has conspicuous tail racquets. In typical motmot fashion, perches quietly for long periods of time anywhere from the understory to the canopy, occasionally flicking its tail side to side. Gives a low single “whoop” call.
African Red-rumped Swallow
Cecropis melanocrissus
Brightly-colored swallow with a deeply forked tail, pale orangish rump, black squared-off undertail coverts, and an incomplete orange collar. Color of underparts varies geographically from pale whitish to rufous, with sparse or no streaking. Juveniles average paler and lack extensive orangish tones; may resemble house-martins but note deeply forked tail. Builds mud nests on rocks as well as human structures, and forages over a wide variety of open habitats. Frequently gives a short, sparrow-like “twi’wit.” Very similar to European Red-rumped Swallow, but with little or no streaking below.
