Fulvous-chinned Nunlet
Nonnula sclateri
Chocolate-brown nunlet of mature rainforest. Usually fairly rare within its range; seems to occur mostly in upland ‘terra firme’ rainforest, where it occurs singly or in pairs in the undergrowth. Even-brown plumage and dull-orange patch at base of bill distinguish it from Rufous-capped Nunlet, which has a bright red-orange crown and orange throat and breast. Its song is a slow series of rising whistled “weep” notes, given at a rate of about one note per second.
识别特征
The fulvous-chinned nunlet is 14 to 15.5 cm (5.5 to 6.1 in) long. Two males weighed 15.4 and 17 g (0.54 and 0.60 oz) and two females 19 and 19.9 g (0.67 and 0.70 oz). Its upperparts, wings, and tail are dull brown. Its lores are reddish brown and the cheeks dark gray. The chin is pale rufous ("fulvous") that blends to reddish brown on the throat and breast. The center of the belly is whitish and the flanks dull fulvous. The eye is brown with a narrow coral red or reddish purple ring around it. The maxilla is black, the mandible dark gray to greenish gray, and the feet gray to olive gray.
分类信息
The fulvous-chinned nunlet is monotypic. Its relationship to others of its genus has not been detailed but it is believed to be most closely related to the rusty-breasted nunlet (N. rubecula) and brown nunlet (N. brunnea). It has sometimes been considered conspecific with the latter.

分布与栖息地
The fulvous-chinned nunlet is found in southwestern Amazonia south of the Amazon River, from eastern Peru and northern Bolivia east in southwestern Brazil as far as the Madeira River. It is entirely a bird of humid lowland forest, seldom being found above 300 m (980 ft) of elevation. It primarily inhabits the understory of upland terra firme forest but has also been reported at the edges of seasonally flooded várzea forest.

Eurasian Jay
Garrulus glandarius
An inhabitant of woodland, forest, parkland, and gardens with larger trees, especially oaks. Note stout black bill, thick black mustache, and black-and-white wing pattern with a patch of blue on the shoulder. White rump usually obvious in flight. Varies significantly across wide geographic range. Typically rather shy and difficult to see well, but sometimes feeds out on open ground; often seen flying across roads. Wide vocal repertoire: typical call a dry “scaaaaak,” as well as varied warbling and hooted notes.
Red-winged Prinia
Prinia erythroptera
Long-tailed warbler with pale underparts and a rufous wing. The color of the head and back is grayish in breeding plumage and brown in non-breeding plumage. Found in areas of lush woodland with tall grass. Usually in the undergrowth, but will perch up sometimes, as when singing. The song is a fast series of whistled calls by one bird, often accompanied by “tik” notes from another. Similar to Tawny-flanked Prinia, but separated by the rufous wing and lack of a pale eyebrow.
Crimson-crowned Fruit-Dove
Ptilinopus porphyraceus
A colorful dove that often sits motionless in the canopy. Males are distinctive, with a bright silver face and chest, a purple forehead, and a bright yellow tip to the tail. Female similar but more subtly colored. Female resembles female Many-colored Fruit-Dove, but has a bolder crimson forehead and a less contrasting green neck. Call is usually two low cooing notes followed by an accelerating, messy cacophony of similar notes.
