Crimson-mantled Woodpecker
Colaptes rivolii
Medium-sized woodpecker found in the subtropical and temperate zones in the Andes from Venezuela to Bolivia. Stunning and unlikely to be mistaken: bright red above and yellow below with obvious pale cheek and dark scalloping on breast. Fairly common but sometimes inconspicuous. Look for singles or pairs following mixed-species flocks, usually in the middle to upper levels of mossy cloud forest. In addition to foraging vertically on trunks in typical woodpecker fashion, seems adept at hitching along smaller horizontal branches.
识别特征
The crimson-mantled woodpecker is 23 to 26 cm (9.1 to 10 in) long and weighs 85 to 112 g (3.0 to 4.0 oz). Males and females have the same plumage except on their heads. Adult males of the nominate subspecies C. r. rivolii have a red crown. Their face is mostly pale yellow with a dark red malar stripe and a black chin and throat. Adult females have a black crown and malar stripe. Both sexes have a crimson red nape and mantle; their rump and uppertail coverts are black. Their wings are bronzy red and their tail is black. Their underparts are yellow with black and red scallops on the breast and sometimes black spots on the belly. Their bill is black, their iris red-brown to brown, and the legs pale gray. Juveniles are generally duller than adults and have no red on the breast; the male's crown is blacker.<p>The other subspecies of crimson-mantled woodpecker vary little from the nominate with the exception of C. r. atriceps. Males of that subspecies have a black crown that is more extensive than the female's. Both sexes have no red on the breast and their wings are less red than those of the nominate.
分类信息
The crimson-mantled woodpecker was originally described as Picus Rivolii. It was later placed in genus Hypoxanthus that was still later merged into Piculus; since about 2007 it has been moved into Colaptes by taxonomic systems.<p>The American Ornithological Society, the International Ornithological Committee, and the Clements taxonomy recognize these six subspecies of crimson-mantled woodpecker:<p>BirdLife International's Handbook of the Birds of the World (HBW) treats C. r. atriceps as a separate species, the black-crowned woodpecker.<p>The specific epithet rivolii honors French ornithologist François Victor Masséna, third Duke of Rivoli and third Prince of Essling.<p>This article follows the six-subspecies model.

分布与栖息地
The subspecies of crimson-mantled woodpecker are found thus:<p>The crimson-mantled woodpecker inhabits the interior and edges of humid montane forest and the lower edge of the páramo zone. In Ecuador it mostly ranges at elevations between 2,000 and 3,300 m (6,600 and 10,800 ft).

行为
The crimson-mantled woodpecker forages at any level of the forest, typically on moss- and lichen-covered limbs but also on trunks. Its primary food is small arthropods, especially ants; it also feeds on fruit. It usually forages singly or in pairs, but does regularly join mixed species feeding flocks. It shuns the introduced shrub gorse.<p>The crimson-mantled woodpecker's breeding season has not been defined but appears to vary geographically. One author surmised that it spans June to November in Peru and another suggested that (possibly species-wide) it includes February to March. It nests in tree cavities but nothing else is known about its breeding biology.<p>What is thought to be the song of the crimson-mantled woodpecker's most widespread subspecies brevirostris is "a series of fairly monotone, rapid metallic notes...kee'r'r-ker'r-ke'r'r. The apparent song of atriceps is a "descending low churr...grr'r'r'r'l". The species also makes "a rising REE?" call. The crimson-mantled woodpecker drums, but not frequently.

Slaty Spinetail
Synallaxis brachyura
Small, dark, and long-tailed. Difficult to see well. Overall gray with rufous wings and crown. Sexes alike. Stays hidden in weedy, tangled undergrowth at the edges of fields and secondary forest. Distinctive song often heard emerging from impenetrable thickets: a low, stuttered chatter.
Kolombangara Monarch
Symposiachrus browni
A small black-and-white monarch. Mostly black above with a black head, back, and chest. Note the distinctive white cheek spot and large white wing patch. Note the significant amount of white on undertail. Endemic to Kolombangara, New Georgia, Vangunu, Rendova, and Tetepare, in the southwestern Solomon Islands. Prefers primary forest, but tolerates secondary growth. Occurs up to about 600 meters of elevation. Voice commonly consists of long pulsing whistles or harsh chattering.
Blue-capped Fruit-Dove
Ptilinopus monacha
A small, mostly green fruit-dove with a blue forecrown and a yellow undertail. Blue forehead is bolder in males, bordered with a thin, well-defined yellow line. Juveniles show yellow fringing on wings. Occurs singly, or in groups at fruiting trees, within lowlands and lower hills in a variety of wooded areas, including forests, mangroves, and plantations. Told from other fruit-doves by the dark head with a blue forecrown, with the yellow line a further distinguishing feature in males. Call is a soft, descending, incessant “woo-oo.”
