Peacock Coquette
Lophornis pavoninus
Tiny hummingbird of tepui highlands. Both sexes distinctive: males have long cheek tufts with black spotting, while females are heavily streaked below. Both have a white rump band like other coquettes. Found only in humid forest and scrub in the tepui region. Feeds on nectar by infiltrating territories of larger hummingbirds; also presumably eats tiny insects. May be seen resting on exposed perches. Both sexes are darker than other coquettes in range, and this species typically occurs at higher elevations than others.
识别特征
The peacock coquette is about 9.7 cm (3.8 in) long. The male of the nominate subspecies has a glittering golden green head with a black line through its middle. Its upperparts are shiny dark green with a white band across the rump. The tail is purplish bronzy and slightly forked. It has long shiny green cheek tufts with large blackish blue spots at the ends and a rufous patch with a white dot near the eye. Its underparts are grayish green. The female does not have the cheek tufts. Its upperparts are golden bronzy with a buffy white band across the rump. Its tail is grayish; the feathers have a wide purplish bronzy band near the end and the outermost pair have white tips. The throat is white with black streaks and the rest of the underparts are mottled black, white, and green. Subspecies L. p. duidae is similar to the nominate but its black crown line and the rufous patch on the cheek are smaller.
分类信息
The peacock coquette and the festive coquette (Lophornis chalybeus) were for a time placed in genus Polemistria. (During that period and after, what is now the butterfly coquette (L. verreauxii) was treated as a subspecies of festive coquette.) <p>The peacock coquette has two subspecies, the nominate L. p. pavoninus and L. p. duidae.

分布与栖息地
The nominate subspecies of peacock coquette is found on Cerro Ptari-tepui and in Sierra de Lema in southeastern Venezuela's Bolívar state; on Mount Roraima where Venezuela, Brazil, and Guyana meet; and in the Merumé Mountains of Guyana. Subspecies L. p. duidae is found on Cerro Duida and nearby smaller tepuis in southeastern Venezuela's Amazonas state. The species inhabits the interior, clearings, and edges of rainforest and cloud forest at elevations between 500 and 2,000 m (1,600 and 6,600 ft).

行为
The peacock coquette is thought to be mainly sedentary but appears to make migratory or nomadic movements in Sierra de Lema.<p>The peacock coquette forages for nectar in the forest canopy, usually alone but sometimes in small groups. Its diet also includes small arthropods that it apparently gleans from foliage.<p>The peacock coquette's nesting season is unknown. The female builds a cup nest suspended from a horizontal branch about 2 m (7 ft) above the ground. The clutch size is two; incubation lasts 13 to 14 days and fledging occurs about 20 days after hatch.<p>The peacock coquette's vocalizations have not been described, and as of February 2022 no recordings are available at Xeno-canto or Cornell University's Macaulay Library.

Java Sparrow
Padda oryzivora
A small, plump finch with a very thick pink bill. The black head and white cheek patch are distinctive. Juveniles have a similar color pattern but are grayer. Social; forages in flocks and roosts communally. Forages in rice fields, grasslands, meadows, and urban and suburban areas (in introduced range). Call consists of one or more musical chirps. Native to the Indonesian islands of Java and Bali, where now quite rare. Introduced widely across the globe including India, Philippines, Venezuela, Puerto Rico, and the Hawaiian Islands.
White-winged Robin
Melanodryas sigillata
A fairly small bird of upper montane forest. An all black bird with an obvious white mark in the wing. Western birds also have a white mark at the shoulder. Perches low down, often on vertical, mossy trunks, scanning the ground for insects. Similar to White-rumped Robin but does not overlap in altitude. Also similar to Pied Bushchat of grasslands, but White-winged Robin is found in forest and lacks the white rump. Voice, a medium-pitch, descending trill and rasping notes.
Sooty-capped Babbler
Malacopteron affine
Bland, unremarkable-looking medium-sized babbler of open forest, forest edges, clearings, brushy riparian, and overgrown margins of cultivation in lowland and foothill areas. Extremely generic-looking, with no bright colors, a medium-length tail, and an average bill. Evenly-proportioned body gives it a rather bulbul-like outline. Note unmarked gray face, dark gray crown, dark rufous tail, and faint brownish wash on the chest. Especially similar to Moustached Babbler, but note present species’ darker crown, plain face (no moustache), and more slender bill. Scaly-crowned is also similar, but has a bright rufous patch on the forecrown. Plainly-colored Pellorneum babblers can be confusing, but note differences in proportions and profile. Most frequently-heard song is a beautiful but eerily human-like rising series of even whistles; when duetting, one bird often gives explosive “wik!” calls in response. Also gives a quicker, more cheery, and less human-like version of the song, as well as a short melancholy up-and-down series of whistles.
