Marmora's Warbler
Curruca sarda
A fairly uniform lead-gray warbler with a red eyering and orangey legs. Females are brownish-gray overall, with a paler throat and no black lores. Breeds only on Sardinia, Corsica, and a few smaller adjacent islands, in open scrubby habitats on mountainsides and rocky coastal areas; winters in open grassy and shrubby habitats in North Africa. Song is a complex twittering similar to other warblers in the same group.
识别特征
These are small, long tailed, large-headed birds, overall very similar to their close relatives in the Dartford warbler group. Marmora's warblers are grey above and below, lacking the brick-red underparts of the Dartford warbler. Adult males have darker patches on the forehead and between the eye and the pointed bill. The legs and iris are red. The song is a fast rattle. Immature birds can be confused with young Dartford warblers, which are also grey below, but Marmora's have a paler throat. Their iris is dark.
分类信息
Marmora's warbler was formerly described in 1820 by the Dutch zoologist Coenraad Jacob Temminck under the binomial name Sylvia sarda. Temminck based his account on a manuscript by the Italian soldier and naturalist Alberto della Marmora that had been read at the Academy of Turin in August 1819. Marmora's warbler is now one of 27 species placed in the genus Curruca that was introduced by the German naturalist Johann Matthäus Bechstein in 1802. The species is monotypic: no subspecies are recognised.

分布与栖息地
It breeds on Mediterranean islands, typically including Corsica and Sardinia. The smaller Balearic Islands bird is given specific status as Balearic warbler, Curruca balearica. These two seem to form a superspecies which in turn groups with Tristram's warbler and the Dartford warbler. They are generally resident but some birds migrate south to winter in north Africa. They are rare vagrants to northern and western Europe. These small passerine birds are found in open country with thorny bushes and heather. 3-5 eggs are laid in a nest in a bush. Like most warblers, they are insectivorous.

Masked Fruiteater
Pipreola pulchra
Chunky green bird with a broad, blunt bill. Males have a bright orange bill, a blackish face, a yellow-orange necklace that bleeds into the breast, and a yellow lower belly; females are nearly entirely green with faint streaking below and a dull orange bill. Notice the females’ dull olive legs and streaked, not scaled pattern underneath, which distinguish it from the similar, orange-legged female Scarlet-breasted Fruiteater. Perches inconspicuously in the mid-story of humid montane forest, where it is often found around fruiting trees and occasionally joins mixed-species flocks.
Morelet's Seedeater
Sporophila morelleti
Fairly common little bird of grassland and weedy areas in the tropical lowlands and foothills. Occurs from Texas to Panama. Often in flocks, mixing readily with other “weed-eating” small birds. Plumage is very variable, but all birds have a stubby dark bill with a curved culmen. Usually shows two whitish wingbars. Breeding plumage males with a black cap and bold white collar are usually outnumbered by female-plumaged birds, which are plain brownish, sometimes showing buffy wingbars.
African Thrush
Turdus pelios
This widespread thrush shows a large amount of geographical variation. The upperparts are generally gray-brown, while the underparts can be buff, gray, or rufous. All across the range, shows a yellow bill. Found in a range of habitats, including forest edge, woodland, gardens, and cultivation. In areas without Abyssinian Thrush, also occurs in montane forest. The song is a pretty, variable series of chatty whistles and trills which can continue for a long time without a pause. Similar to Abyssinian Thrush, but found at lower elevations in areas of overlap, and is generally paler, with a paler yellow bill.
