Swainson's Sparrow
Passer swainsonii
A drab sparrow of northeastern Africa. The head and underparts are gray, the wing and back are brown, and the rump is rufous. Generally common within its range in all habitats except closed-canopy forest. Fond of human habitation. Very similar to Northern Gray-headed Sparrow, but there is little overlap in range, and Swainson’s has darker underparts. Also very similar to Parrot-billed Sparrow, but slightly smaller and slimmer-billed, with paler underparts. The call is a ringing “churp.”
Identification
The Swainson's sparrow reaches a body length of 16 centimetres (6.3 in). There is no conspicuous sexual dimorphism.<p>It is often considered a race of grey-headed sparrow, but it tends to be darker, especially on the head and shoulders. There is a white bar on the shoulder, but this is not always visible. Similarly, the pale chestnut tail and rump is not always visible.

Range and habitat
It occurs in the highlands of Ethiopia and Somalia, and in some of Sudan, South Sudan, Eritrea, Djibouti, and Kenya. Apart from the far west, it is common throughout its range. Some populations show seasonal migrations.<p>The habitats of the Swainson's sparrow are mountainous areas, marshes, open forest areas, savannas and shrubby grasslands. However, most often it occurs in human settlements and their surroundings. In Eritrea, it lives mostly on the open plateau at an altitude of 1,200 metres (3,900 ft) above sea level, and in Ethiopia it occurs in areas of 1,200–4,500 metres (3,900–14,800 ft) above sea level.<p>In Ethiopian towns it is the common sparrow, similarly to the house sparrow in most of Eurasia.

Behavior
Swainson's sparrows eat mostly seeds of grasses and cereals, and insects.<p>The nest is a loose ball assembled from grass and feathers. A nest may be built on branches, or in the crown of palm trees, or in tree hollows. The birds also use cavities in buildings, and the old nests of the Ethiopian swallow and African sand martin. They have been observed once removing nestlings of the African sand martin to take over their nests. A clutch contains three to six eggs. They are white with brown and gray spots. The breeding season falls in Eritrea during January to March and May to November, in Ethiopia breeding may occur from April to December.<p>Outside the breeding season they live in flocks, sometimes consisting of several hundred individuals. Swarms of this size can cause some damage when they come in agricultural regions and gardens.

Other Birds
Yellow-crowned Canary
Serinus flavivertex
Colorful seedeater with an olive-green back, black wings with two yellow wingbars, and a mostly yellow head and underparts. Females and immatures are duller, with more brown tones and streaking. Found in open montane habitats including grassland, cultivation, forest edge, and heath. The song is a high-pitched, twittering jumble. Similar to White-bellied Canary, but found in different habitat, has bolder wingbars, and lacks a moustache facial mark.
Yellow-bellied Tanager
Ixothraupis xanthogastra
A small, colorful bird of forest canopy. Mostly bright green spotted heavily with black; the wings are bluish and the belly clear yellow. Occurs in humid lowland and Andean foothill forests in central and western Amazonia; in eastern part of range it is mainly found in tepui foothills but is perhaps overlooked in lowlands. Usually observed in mixed-species flocks, especially with other tanagers, moving quickly through canopy feeding on insects and fruit. Makes a variety of high-pitched calls, especially in flight, similar to other small tanagers and not particularly helpful in identification. Told from Speckled and Spotted tanagers by bright yellow (not white) belly, and from Dotted Tanager by yellow belly and extensive black spotting on head and breast.
Viridian Metaltail
Metallura williami
Short-billed hummingbird found near tree line in the high Andes. Male is deep green with a dark and sometimes glittering throat patch; female is similar but lacks throat patch and is scaled buff or rufous below. Tail color varies geographically; it can be green or blue, and it can even show a bit of rufous on top, though never as much as the tail of Tyrian Metaltail. Feeds on small flowers in páramo and at the edge of elfin forest.
