Red-headed Tanager
Piranga erythrocephala
Fairly small tanager of pine-oak and tropical forest in foothills and highlands of Mexico; endemic. Found mainly in the canopy, usually in pairs or small groups that sometimes join mixed-species feeding flocks. Distinctive male has brilliant red head (with small black mask), greenish upperparts, and yellow underparts. Female is rather drab greenish and yellow overall with dusky gray cheeks. Female looks similar to female Hepatic Tanager but much smaller with smaller, stubbier bill and paler belly. Calls are high twitters similar to Bushtit.
识别特征
The red-headed tanager is approximately 15 cm (5.9 in) long and weighs 19.9 to 24.5 g (0.70 to 0.86 oz). The nominate male's forecrown, face, throat and upper chest are red and the rest of the upperparts bright yellow-olive. The rest of the underparts are olive-yellow. It has a narrow black mask. The female's forecrown is yellow and the rest of her upperparts yellow-olive. The throat and chest are yellow that fades to buffy white toward the vent area. The juvenile male looks like a bright female. P. e. candida is similar to the nominate but duller and darker.
分类信息
English naturalist William John Swainson described the red-headed tanager in 1827 as Spermagra erythrocephala from material collected by William Bullock and his son from a specimen from Temascaltepec in Mexico.<p>The red-headed tanager and the other species of genus Piranga were originally placed in the family Thraupidae, the "true" tanagers. Since approximately 2008 they have been placed in their current family. It and the white-winged tanager (Piranga leucoptera) have sometimes been placed in genus Spermagra.<p>The red-headed tanager has two recognized subspecies, the nominate Piranga erythrocephala erythrocephala and P. e. candida.

分布与栖息地
The red-headed tanager is endemic to Mexico. The nominate is found discontinuously from Jalisco state south to eastern Oaxaca. P. e. candida is found further north, from southern Sonora and Chihuahua south to Jalisco, and has been recorded further south outside of breeding season. It uses a variety of wooded habitats including semi-humid and moist montane forest, pine-oak forest, evergreen forest, and open woodland with scrub. It can also be found along the edges of forest and in plantations. In elevation it ranges from 900 to 2,600 m (3,000 to 8,500 ft).

行为
The red-headed tanager forages in pairs or small groups for insects and small fruit like berries. It favors the mid level of the trees or higher and tends to stay in the foliage though it will sometimes forage at the ends of branches.<p>The red-headed tanager's nest is a cup of fine twigs placed at middle to upper height in a tree. No other information about its breeding phenology has been published.<p>The red-headed tanager's song is "a long, slow ...'chur chew che-wier chéé-chur wee chur cheer chéé-chur ...'" or "tsi-tsi tsee-tsee". It has several calls.

Rose-collared Piha
Lipaugus streptophorus
Medium-sized, gray bird of tepui highlands. Male is unmistakable with pink collar and undertail coverts; female lacks pink collar. Generally occurs above 800 meters on tepui slopes, where it is an uncommon resident of the mid-story and canopy of tall forest; moves sluggishly and can be difficult to detect when not vocalizing. Feeds mainly on fruit, and is usually encountered alone but may associate with other species at fruiting trees. Most common vocalization is a single sharp rising whistled note, which may be lengthened and slurred downward, given at fairly long intervals. Size, shape and behavior recall Screaming Piha, which does not occur in tepui highlands.
Apolinar's Wren
Cistothorus apolinari
A small buffy-brown wren with a very limited range in central Colombia. Look for a streaked back and dark barring on the wings and tail. Compared with Sedge Wren, Apolinar’s has a grayer throat and eyebrow. Found in marshes with tall cattails and sedges from around 2,000 to 3,500 m. Can be skulking and difficult to see, but occasionally perches up to sing. Listen for strange harsh chirring song.
Green-capped Tanager
Stilpnia meyerdeschauenseei
Handsome tanager with a small range in the Andes of western Bolivia and southeastern Peru. It is pale with blue wings and tail, black mask, and buffy crown and vent. Similar to Burnished-buff Tanager, but has a duller, less rusty crown and is found at higher elevations. Inhabits lightly wooded areas and edge, avoiding areas of dense forest.
