Rufous-chested Swallow
Cecropis semirufa
This large swallow has a brick-red rump and underparts and dark blue upperparts. It is told from other swallows by the metallic-blue patches on the side of the head that cover the ears and eyes. It is resident near the equator and is a wet season breeding visitor in the north and south of its range. The Rufous-chested Swallow flies strongly, with frequent swoops and changes of course, over sparse woodland, grassland, wetland edges, and other open habitats. In flight it differs from similar swallows by the color of the forward part of the underwing: buffy in Rufous-chested Swallow and white in Mosque Swallow, which also has a pale throat.
识别特征
The red-breasted swallow is similar to the mosque swallow but is slightly smaller and has longer tail streamers, both species having a blue crown and mantle contrasting with a rufous rump and underparts, In the red-breasted swallow the dark crown extends below the eye and there is no white on the underwing. The juvenile is similar to the red-rumped swallow but has blue on the side of the head rather than dull red.

分布与栖息地
The red-breasted swallow is a bird of dry open country. In more wooded areas it is replaced by the similar mosque swallow. It builds a closed mud nest with a tubular entrance in a cavity or under bridges and similar structures. It will use deserted buildings, tree holes or caves, and has benefited from the construction of railway bridges and similar structures. The red-breasted swallow is found over most of Africa south of the Sahara from the Eastern Cape north to northern Namibia and southern Angola in the west and Mozambique in the east, with a disjunct range from Senegal south to northern Angola east to Uganda, southwestern Kenya and northwestern Tanzania.<p>The red-breasted swallow is migratory in most of its range. In southern Africa it is a summer visitor, nesting between July and March with most of the population migrating to equatorial Africa, although a few remain all year. In some parts of its range, e.g. in southeastern Nigeria to Gabon, it appears to be resident, but it is mostly a rainy season breeding visitor across its northern range.

White-throated Flycatcher
Empidonax albigularis
Rather drab, small flycatcher of marshes and semiopen areas with bushes and hedges; winters mainly in lowland marshes. Flicks tail upward when perched. Looks similar to several other species in the genus Empidonax. Best identified by its distinctive call: a burry, slightly sneezy “rreeah,” quite different from Willow Flycatcher, which often occurs alongside White-throated in winter. Also note the whitish throat, buffy wingbars and flanks, and the lack of a distinct pale eyering.
White-sided Flowerpiercer
Diglossa albilatera
Small flowerpiercer, male all slaty blackish and female fairly dark olive-brownish. Both sexes show white flash on sides, mostly obscured by wings but usually partially visible, especially with its frequent wing flicks. Bill is upturned with a hook at the tip, typical of a flowerpiercer. Found at middle elevations, around 1,800–2,800 m, in the Andes from Venezuela to Peru. Usually at forest edge or shrubby areas. Can be found singly, in pairs, or following a mixed-species flock.
Silver-eared Mesia
Leiothrix argentauris
Beautiful small babbler with a black head, bright silver ear, orange underparts, and a bright red wing patch. Travels in noisy flocks through hill and submontane forest, sometimes in single-species groups and occasionally with other species. Unfortunately a common target of the cage bird trade, and escapees are often seen outside of their native range; in some areas, such as Hong Kong, they have even established self-sustaining populations. Warbled song often given as birds move around in flocks.
