White-sided Hillstar
Oreotrochilus leucopleurus
Small hummingbird of the Andes from southern Bolivia through Argentina into central Chile; found in rocky and shrubby valleys, villages, and any open or semiopen areas with flowers. Often builds nest under eaves of buildings or bridges: a bulky cup of plant material and wool to insulate against cold nights. Fairly common. Readily identified in most of range by extensively white tail. Male has an emerald green gorget and a broad blue-black stripe on belly. Female is rather drab, but note slightly decurved bill, spotted throat, and tail pattern.
识别特征
The white-sided hillstar is 13 to 15 cm (5.1 to 5.9 in) long and weighs 7.9 to 8.4 g (0.28 to 0.30 oz). Adults have a medium length slightly decurved black bill. The adult male has drab brown upperparts. It has a shiny green gorget with a black border that separates it from the white breast and belly. The belly has a wide blue-black stripe down its middle into the vent area. The somewhat rounded tail is bronzy black and its outer feathers have white at the base. The female is also dull brown above, and below as well. Its throat is pale with fine dark speckles. The tail is greenish black and the outer three or four pairs of feathers have much white at the bases and tips. The juvenile is overall more grayish than the adult and the male has a dark blue-green gorget.
分类信息
The white-sided hillstar was at one time proposed to be a subspecies of Andean hillstar (Oreotrochilus estella) but major taxonomies retain it as a species. It is monotypic.

分布与栖息地
The white-sided hillstar is found in the Andes from central Bolivia's Cochabamba Department south through Chile to the Biobío Region and Argentina as far south as Santa Cruz Province. It inhabits puna grasslands with dwarf shrubs, cacti, and Puya. In elevation it generally ranges from 1,200 to 4,000 m (3,900 to 13,100 ft) but may go higher even to the snow line.

行为
The white-sided hillstar mostly leaves Chile during the Austral winter but some individuals simply move to lower elevations. There might also be some late winter or early spring movement further north than Cochabamba in Bolivia.<p>The diet and feeding strategy of the white-sided hillstar are not well known but are believed to be similar to those of the closely related Andean hillstar. That species feeds on nectar at a variety of flowering shrubs, cacti, and trees, and perches to feed rather than hovering. It also gleans arthropods from vegetation and sometimes catches them on the wing.<p>The white-sided hillstar breeds in November and December. It glues its large cup nest to a vertical rock face in a well-protected spot. The clutch size is two eggs. Little else is known about the species' breeding phenology.<p>The white-sided hillstar's vocalizations are not well known. It does make "a repeated short 'tsit'" call and also "a fast twittering during chasing or display".

Antillean Siskin
Spinus dominicensis
A gregarious small seed-eating bird of pine forests and forest openings that also visits agricultural areas near dry scrubby forests. The male is unique in appearance with green upperparts, yellow underparts, a black head, and a thick pale bill. Females of this species resemble female and nonbreeding Village Weavers, but the Village Weavers are substantially larger, have a distinct pale eyebrow, a dark bill and pink legs. Calls include a “jut-jut,” a shrill and buzzy “zzhhreeeee,” and a buzzy insect-like “zzzzzzzzzt” that is upward inflected.
Miombo Rock-Thrush
Monticola angolensis
Attractive rock-thrush in which males and females are strikingly different. Males have a gray head and back and rufous underparts, while females have a brown, heavily scalloped head and back and mostly white underparts. Found very locally in miombo broadleaf woodland. The song consists of musical, vibrating whistles. Similar to migratory Rufous-tailed Rock-Thrush, but male lacks white back and female has little or no scalloping below.
Sula Jungle Flycatcher
Cyornis colonus
A nondescript brown flycatcher with a rufous tail and rump. Note the hook-tipped bill, white throat, and pale gray unstreaked underparts. Juveniles paler above with buff fringes on some wing feathers. Occupies shady areas of the forest understory, including bamboo stands, in lowland areas. Restricted to the Sula Islands. Longer-billed and longer-tailed than female Snowy-browed Flycatcher, and further differs in absence of pale forehead and in having entirely gray underparts. Song is a quiet phrase of thin, high-pitched whistles, descending at the end, “tsee-tser-soo-loo-soo.”
