Bicolored Conebill

Conirostrum bicolor

Small bluish tanager with a thin pointed bill. Both sexes are similar: blue-gray above and paler buff below with pinkish legs. Similar to Pearly-breasted Conebill, which has slightly paler upperparts and lacks buff tones below. Found on the coast in mangroves and in Amazonia in flooded forest along some major rivers.

识别特征

The bicolored conebill is 11.4 cm long and weighs 11 g. The adult is grey-blue above and buff-tinged grey below, with red eyes, pink legs and a sharp, pointed bill. The primary flight feathers are bluish with brown edgings. The sexes are similar, although the female may be a little duller, but immature birds are greenish above and have pale yellow underparts. Birds sometimes breed in immature plumage.

Rosy Starling

Rosy Starling

Pastor roseus

Adult is unique, a vision in glossy black and pale pink. Juvenile is brown with an orange bill. Breeds in colonies on steppes and winters in open and wooded habitats. Gathers in huge numbers to roost, often mixing with other species at roost sites. Flocking birds keep up a constant cacophony of dry chattering calls. 

Principe Seedeater

Principe Seedeater

Crithagra rufobrunnea

An incredibly dowdy small seedeater with a pink-horn bill and a pale throat. On São Tomé its color is gray-brown and on Príncipe more buffy-cinnamon. On São Tomé it is a common resident in most habitats from primary forest to suburban gardens up to 1500 meters of elevation; on Príncipe it is uncommon and more restricted to forest. Song is variable, but mostly a strident, rapidly delivered series of high-pitched notes “tseet-teet-teet-teet-tseeu-tseeu-tseeu” or similar; call is a slurred “tshweet.” The much larger Sao Tome Grosbeak is chestnut in color and rare in remote forest on São Tomé; Yellow-fronted Canary is much brighter. 

Littoral Rock-Thrush

Littoral Rock-Thrush

Monticola imerina

Chunky, mid-sized robin-like bird. Males are pale gray and orange, while females are gray-brown. Madagascar endemic that is found in coastal spiny forest and scrub in the southwest. Perches up conspicuously. Song is a variable mix of thin whistles and raspy notes. Paler than Forest Rock-Thrush, with little or no overlap in range. Female similar to female Madagascar Magpie-Robin, but smaller and grayer, without white patch in the wing.
