Sooty-capped Hermit
Phaethornis augusti
Large, brownish hummingbird with a long tail. Pale gray below with strong facial markings and a contrasting rufous rump; broad white tail feather tips are a key field mark. Occurs in dry forest and along savanna edge, where it visits widely spaced nectar sources and is often seen moving rapidly between them. Notably curious and will often stop to assess a person before quickly moving on; amount of white in tail is especially evident as bird flies away. Males sing from low perches; song consists of two squeaking notes followed by three faster, higher-pitched ones, given in alternation, over and over. Flight call is a loud squeak, similar to other large hermits. Best told from Long-tailed and Great-billed hermits by paler, grayer coloration and extensive white in tail.
识别特征
The sooty-capped hermit is about 14 to 15 cm (5.5 to 5.9 in) long. Males weigh 4.5 to 6 g (0.16 to 0.21 oz) and females 4 to 5 g (0.14 to 0.18 oz). They are mostly grayish brown above with a rufous rump and uppertail coverts. The next-to-inner tail feathers are longer than the others and all have white tips. Their underparts are gray. The face has a black "mask" with a white supercilium and gular stripe. The subspecies differ slightly in the intensity of the breast and uppertail covert colors and the size of the gular stripe. What was once thought to be a separate species P. fumosus was determined to be a melanistic morph of the nominate sooty-capped hermit.
分类信息
The sooty-capped hermit is closely related to the planalto hermit (P. pretrei) and may form a superspecies with it. Three subspecies of sooty-capped hermit are recognized, the nominate P. a. augusti, P. a. curiosus, and P. a incanescens. A fourth proposed subspecies P. a. vicarius, in the Colombian Andes, cannot be separated from the nominate.

分布与栖息地
Major taxonomic systems place the nominate subspecies of sooty-capped hermit in Venezuela's Coastal Range and eastern Andes and south on the eastern slope of Colombia's Eastern Andes; P. a. curiosus in the isolated Sierra Nevada de Santa Marta of northeastern Colombia; and P. a incanescens on the tepuis of southern Venezuela, western Guyana, and Brazil's Roraima state. The South American Classification Committee (SACC) of the American Ornithological Society places the species in those four countries and also French Guiana and Suriname.

Ochre-fronted Antpitta
Grallaricula ochraceifrons
Small, streaky antpitta found only in a small area of the eastern Andes in northern Peru. Note the strongly marked underparts and the white mustache. Male has a chestnut face and forehead; female lacks this and has a much thicker eye-ring. Inhabits the understory of epiphyte-laden cloud forest. Unlike most larger antpittas, it is usually seen on a low perch and only occasionally comes down to the ground. Visits a feeder in at least one private reserve. Song is a short, high-pitched whistle given about every 10 seconds.
Gray-breasted Flycatcher
Lathrotriccus griseipectus
Small, scarce flycatcher found in both dry and humid forest in western Ecuador and northwestern Peru. Good field marks are the mostly gray plumage, white “spectacles,” and bold white wingbars. Easy to overlook as it perches quietly inside lower levels of the forest, and often first detected by voice. Typical song is a soft, burry “breer, breer,” sometimes followed by other notes.
Gray-cheeked Green-Pigeon
Treron griseicauda
Chunky green pigeon with comical lime-green “goggles” and a thick white bill. Male has a dark maroon back and shoulders, which the female lacks. Both sexes have a silvery-gray forehead and crown. Female may be confused with female Pink-necked and Orange-breasted Green-Pigeons, but note her gray crown, green spectacles, and bright yellow-green wing feather linings. Inhabits a wide range of wooded areas, from the lowlands into the foothills. Often in pairs, but will also gather in large flocks at fruiting trees. Gives a long, quavering coo, as well as more even-sounding cooing and odd chuckling calls.
