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.

Identification

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.

Taxonomy

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.

Range and habitat

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.

Rusty-crowned Tit-Spinetail

Rusty-crowned Tit-Spinetail

Leptasthenura pileata

Attractive, long-tailed bird found in the high Andes of Peru. Plumage is brown overall with a chestnut crown, speckled throat, and streaked belly. Plumage varies geographically, and birds in southern Peru are much darker below with bolder streaking. Inhabits scrub and woodland with short trees. Vocalizations have a metallic quality; they include a high-pitched trill and a series of sharp chips.

Bronze Parotia

Bronze Parotia

Parotia berlepschi

A fairly large, short-tailed bird of mid-mountane forest canopy in the Foja Mountains. Male is mainly black with white flanks, bronzy-scaled chest and 6 antennalike feathers projecting from the back of the head. Note the blue eye. The female is dull brown above with rufous in the wing, strongly-barred underparts and pale bands above and below the eye. The male dances at a terrestrial display court. There are no other similar birds-of-paradise that co-occur. Vocalizations include loud rasps, rattles or a single or double-note squeak “wi-dik!”.

Papyrus Canary

Papyrus Canary

Crithagra koliensis

This canary is typical in its appearance but unusual in its papyrus-dwelling habits. The male and female are similar but the male is more boldly marked, especially on the face. Found in papyrus swamp and adjacent habitats. Uncommon and inconspicuous. The song is a complex mix of quiet twitters and whistles. Similar to Western Citril, but separated by the lack of a yellow eyebrow. Extremely similar to Southern Citril, and best separated by the more bulging, pinkish bill.
