Black-tailed Flycatcher
Myiobius atricaudus
A fairly small flycatcher with a large distribution from Costa Rica to Brazil. Like other members of the Myiobius genus, has a relatively long, dark tail and a blazing yellow rump. Extremely similar to Sulphur-rumped Flycatcher, which is usually found in more mature forest and has a darker breast. Black-tailed is more likely to be found around forest edge or second growth, but there is overlap. Singles or pairs forage in the understory, often following mixed-species flocks. Often fans its tail. Listen for dry “whit” call.
识别特征
The black-tailed myiobius closely resembles the whiskered myiobius (M. barbatus) and the sulphur-rumped myiobius (M. sulphureipygius) in appearance, with olive upper parts and a yellow rump. The underparts differ in being buff rather than tawny or greyish-olive, but birds living in eastern Brazil tend to have yellowish or yellowish-buff underparts. Another distinguishing feature is the location in which the bird is seen. The black-tailed myobius haunts woodland edges and secondary forests and is less active or acrobatic than the other two species; it is found at altitudes up to 1,400 m (4,600 ft).

分布与栖息地
The species has a patchy distribution in tropical Central and South America. It is present in Costa Rica, Panama, Colombia, Venezuela, Ecuador, Peru (on both sides of the Andes) and large parts of Brazil. Where their ranges overlap, it is generally found in drier habitats than the whiskered myiobius (M. barbatus), and at higher elevations. It generally frequents forest verges and secondary growth, often near water, whereas the whiskered myiobius prefers the interior of forests.

Tumbes Hummingbird
Thaumasius baeri
A plain hummingbird found in dry forest and scrub in southwestern Ecuador and northwestern Peru. It is dull green with light gray underparts, a white spot behind the eye, and a thick, slightly curved bill. Some birds show very faint spots on the throat. Similar to Spot-throated Hummingbird, but throat markings are much less conspicuous or entirely absent. Ranges are also different; Tumbes Hummingbird is found only on the Pacific side of the Andes and does not reach the Marañon drainage.
Olive Whistler
Pachycephala olivacea
Heavily built brownish songbird found in dense wet forests of southeastern Australia and Tasmania. Gray head and white throat contrast with greenish back; pale gray breast band separates white throat from rich olive-brown belly. Much larger than Golden Whistler (which has a yellow undertail area, less distinct throat patch). Many different calls, all with loud clear whistles delivered in slow, smooth manner.
Large-footed Finch
Pezopetes capitalis
Large sparrowlike bird; entirely olive with contrasting gray head and black face. Range does not overlap with other similar-looking sparrows and brushfinches. Often found in pairs or small family groups, usually scratching through leaf litter or low in a tangle in the forest understory. Loud song often heard at dawn. Sexes alike.
