Butterfly Coquette
Lophornis verreauxii
Tiny hummingbird with a white rump band and rusty tail. Adult male is stunning, with a flowing, glittering green beard ending in white spots, an iridescent green face, and a small crest. Female and young male are much plainer than male, but they typically have a white throat with dark patch in the middle, and lack the buffy or rusty tones on the underparts shown by females of several similar species. Distinguished from female Peacock Coquette by lack of streaking on the throat. Inhabits humid lowland and foothill forest and is quite scarce in most of its range. It was previously considered to be a subspecies of Festive Coquette.
识别特征
The butterfly coquette is 7.5 to 9.1 cm (3.0 to 3.6 in) long. The male of the nominate subspecies has a deep green head with a long, red-tipped, green crest and long green "whiskers" with white tips. Its back is green with golden highlights, deep reddish uppertail coverts, and a white band on the rump. The underparts are green but for white thighs and the tail is maroon. The female does not have the crest and "whiskers" but does have a whitish malar patch. The uppertail coverts are a less intense red than those of the male and it has golden highlights on the breast. Both sexes of subspecies L. v. klagesi are darker overall than the nominate, and their uppertail coverts are bronzy olive and the tail bronzy green.
分类信息
The butterfly coquette was formerly treated as a subspecies of the festive coquette (Lophornis chalybeus), and that species and the peacock coquette (L. pavoninus) were also for a time placed in genus Polemistria. In 2019 the South American Classification Committee (SACC) of the American Ornithological Society accepted the festive coquette as a separate species. The International Ornithological Committee (IOC) and BirdLife International's Handbook of the Birds of the World (HBW) adopted the split in 2020. The Clements taxonomy did not make updates in 2020 and adopted the split in 2021.<p>The butterfly coquette has two subspecies, the nominate L. v. verreauxii and L. v. klagesi.

分布与栖息地
The nominate subspecies of butterfly coquette is found from Amazonian Colombia, Ecuador, and Peru into Brazil as far east as Mato Grosso and south into central Bolivia. L. v. klagesi is restricted to the Río Caura watershed in Venezuela's Bolívar state. The species inhabits a variety of humid landscapes including riparian forest, white sand scrub forest, and terra firme forest. It also occurs in secondary forest and scrubby fields. In elevation it ranges as high as 1,000 m (3,300 ft).

行为
The butterfly coquette is essentially sedentary, though some short-distance seasonal movement is thought to occur.<p>The butterfly coquette feeds on nectar, which is mostly sought in the canopy but also at lower levels. The species usually hovers to take nectar but has been recorded piercing the base of flowers to "steal" it. It has been observed trap-lining, visiting a circuit of flowering plants. It does not appear to defend a territory but will dispute conspecifics at a flower patch. The species also eats small insects that it apparently gleans from foliage.<p>The butterfly coquette's breeding phenology has not been studied nor have the nest and eggs been described.<p>The butterfly coquette is usually silent but makes "short tsip or chip" calls when feeding. One audio recording is available at Cornell University's Macaulay Library.

Dark-breasted Rosefinch
Procarduelis nipalensis
Dark medium-sized rosefinch. Male is is dark pink with a lighter throat and eyebrow. Female is dark brown with light wingbars. Both sexes can be similar to Vinaceous Rosefinch, but note male’s different head pattern and female’s unstreaked underparts and noticeable wingbars. Forages on the ground in montane and hill forest, forest edge, and rocky meadows and slopes. Gives a wheezy sparrow-like “wheer.”
Red-cowled Cardinal
Paroaria dominicana
A conspicuous inhabitant of woodland in the Brazilian caatinga, but it is also found in scrubby areas and urban parks where it forages on the ground in pairs or small groups. Note the red head and throat, mostly gray back, black wings, and black tail that is white below. Immatures have a duller orange head. The song is a series of fast melodic whistles.
Malagasy Palm Swift
Cypsiurus gracilis
A very slender gray-brown swift with a long, deeply forked tail that is often held closed, making it look needle-like and pointed. The erratic flight pattern, with frequent direction changes and rapid wingbeats on long, scythe-shaped wings, is distinctive. Less gregarious than other swifts; usually found in pairs or small flocks, and association with other swallows and swifts is usually only fleeting. Forages over a wide variety of habitats with palms, including savanna, coastal scrub, towns, villages, cultivated areas, forest edge, and clearings, from sea level up to 1100 meters of elevation, preferring lowlands. Nests and roosts in palms, especially Hyphaene, Bismarckia, and coconut palms. Gives a high-pitched, metallic “tre-tit-tit-tit-tit-tit-tit-tit” call, solitarily or in unison with others. Separated from other swifts by its longer and thinner tail. Further separated from the larger Madagascar Swift by its much weaker and more fluttering flight.
