Velvet-purple Coronet
Boissonneaua jardini
This medium-sized hummingbird looks all blackish in poor light, but at the right angle, it turns into a dazzling gem with a purple belly and crown, turquoise sides, and greenish wing coverts. Note bright white flashes in the tail. Like other coronets, it holds its wings up for a few seconds when it lands, exposing rich chestnut underwings. Sexes similar. Very restricted range in western Colombia and Ecuador, where it is generally uncommon in moist cloud forest and edges in the lower subtropical zone. Visits feeders.
Identification
The velvet-purple coronet is 11 to 12.7 cm (4.3 to 5.0 in) long and weighs 8.0 to 8.5 g (0.28 to 0.30 oz). Both sexes have a short, straight, black bill and a white spot behind the eye. Both have a notched tail, though the female's is less deeply indented than the male's, and both have small white puffs on the legs. Males have a velvety black head with a glittering purplish blue crown; the rest of the upperparts are shining bluish green. The throat is velvety black and the breast and belly glittering purplish blue. The underwing coverts are cinnamon and show in flight. The central tail feathers are black and the rest white with black tips and edges. Females are similar to males but duller overall, and the breast and belly feathers have buff to grayish brown fringes.
Taxonomy
The velvet-purple coronet shares genus Boissonneaua with two other coronets, the chestnut-breasted (B. matthewsii) and buff-tailed (B. flavescens). It is monotypic.

Range and habitat
The velvet-purple coronet is found along the Pacific slope of the Andes from southwestern Colombia's Chocó Department to northwestern Ecuador's Pichincha Province. It mostly inhabits the interior and edges of wet mossy primary and secondary forest, but also occurs in shrubby landscapes. It has been recorded between 800 and 1,700 m (2,600 and 5,600 ft) in Ecuador and between 350 and 2,200 m (1,150 and 7,220 ft) in Colombia, but is most common above 1,200 m (3,900 ft).

Behavior
The velvet-purple coronet is generally sedentary, but seasonal elevational movements are known from Colombia.<p>The velvet-purple coronet is territorial and defends clusters of flowers from other nectar-feeding birds. It forages at any forest level from the lower strata to the canopy. It feeds by clinging to the flower, holding its wings open for a second or two after landing. In addition to feeding on nectar it captures small insects by hawking from a perch.<p>The velvet-purple coronet's breeding season spans at least from January to March but might extend as far as September. It builds a cup nest of moss and lichen on a horizontal branch or in a small fork. The female incubates the clutch of two eggs. The incubation period and time to fledging are not known.<p>The velvet-purple coronet's courtship song is described as a "series of alternating harsh and soft whistles, 'si, siii, si, siii, si, siii...'".

Other Birds
Savanna Nightjar
Caprimulgus affinis
Well-camouflaged nightbird, usually encountered roosting on gravel riverbeds, open areas in grasslands, rooftops, or roadsides. Sometimes found in small loose flocks when roosting. Fairly well adapted to urban life in some parts of its range and often found in towns and city edges. Intricately patterned gray-brown with less white than other nightjars; only males have a fairly small white patch on the wing near the tip. Most often detected by its distinctive, high-pitched, burry “chree-ik” song, repeated over and over.
Yemen Warbler
Curruca buryi
Unusual and distinctive warbler of the southwest Arabian highlands. Gray-brown, with a darker cap, paler throat, and pale eye. Found in dry montane scrub and woodland, including juniper and acacia woodland. Generally skulking, but will sometimes come into the open. The song is a loud and distinctive, but variable, series of mix of musical warbled notes. Scratchy, scolding calls are often given on their own, but can also be mixed into the song. Similar in overall shape and size to several other warblers, but identified by the browner overall coloration, with more dusky underparts. Further separated from confusion species like Arabian Warbler by the pale eye.
Dark-crowned Heleia
Heleia dohertyi
A distinctive small songbird with olive upperparts, a bright yellow underside, and a diagnostic head pattern: chocolate-brown head crest with indistinct white flecking, black mark between the bill and the eye, and white brow. Singles, pairs, or small groups frequently join mixed-species flocks in forests, edges, and cultivated areas in lowlands and lower hills. Restricted to the Lesser Sundas. Vocalizations include soft chattering calls, thin “tsip” notes, harsh “kit-up” calls, and a complex warbled song comprising whistled and whipping notes.
