Dusky Starfrontlet
Coeligena orina
Rare hummingbird known only from a few locations in the northern half of Colombia’s western Andes. Large and long billed with iridescent green belly and rump. Male has glittering green forehead and sapphire throat patch. Female lacks these features and instead has a buffy throat and mustache. Inhabits humid forest at high elevations up to tree line. Feeds on a variety of flowers, and regularly visits feeders in the reserve that bears its Spanish name, the Colibrí del Sol Nature Reserve above the town of Urrao.
Identification
The dusky starfrontlet is about 14 cm (5.5 in) long. Males weigh 6.9 to 7.2 g (0.24 to 0.25 oz) and females 6.7 to 7 g (0.24 to 0.25 oz). The male has a glittering blue-green to golden green forehead and a velvety black crown, face, and mantle. The back is green with black highlights, the rump and uppertail coverts iridescent golden green, and the tail a paler green. The throat and breast are dark green, like the back suffused with black, and there is a large cobalt-blue spot on the lower throat. The belly and undertail coverts are the same golden green as the rump. The female's crown, face, and upper back are green with blackish tips to the feathers that give a scaly effect. The rump, uppertail coverts, and tail are like the male's but with less iridescence. The throat is a bright cinnamon buff with green spots on the sides, the belly iridescent golden green with dusky inclusions, and the undertail coverts dull golden green with buffy edges.<p>One Spanish name for the dusky starfrontlet is "Colibrí del Sol", which translates to "hummingbird of the Sun".
Taxonomy
The dusky starfrontlet was originally known from a single museum specimen collected in 1951 and described as a full species in 1953. In 1988 its status was reassessed as a subspecies of golden-bellied starfrontlet (Coeligena bonapartei). It was rediscovered in 2004, in what is now the Colibri del Sol Bird Reserve, and additional specimens confirmed its identity as a species. It and the buff-winged starfrontlet (C. lutetiae) are sister species and it is also closely related to the golden-bellied, violet-throated (C. violifer), and blue-throated (C. helianthea) starfrontlets.<p>The dusky starfrontlet is monotypic.

Range and habitat
The dusky starfrontlet is found in only about a dozen sites in a few small areas of the Western Andes of Colombia. The original 1951 specimen and some of the 2004 ones were collected at Páramo de Frontino, Antioquia Department. Others were collected in 2004 at nearby Las Orquídeas National Natural Park in Farallones del Citará on the Antioquia/Chocó border. Further observations have come from Jardín in Antioquia and Cerro Montezuma in Risaralda Department.<p>Specimens and sight records of dusky starfrontlet have come from tall humid forest, elfin forest, and the ecotone between forest and páramo. Most observations have been between about 3,100 and 3,500 m (10,200 and 11,500 ft) of elevation, but there is one record from 2,500 m (8,200 ft).

Hainan Blue Flycatcher
Cyornis hainanus
A small flycatcher found in the midstory of both wooded and bamboo forests in lowland and hill regions. In much of range, male is dazzling sapphire-blue with a dirty-white belly; lack of other markings or warm coloration distinguishes it from other flycatchers. In western parts of the range (formerly treated as a subspecies of Blue-throated Flycatcher), males have an orange upper breast and “notch” in the otherwise blue lower throat. Female is brown with a pale orange throat and chest. Often joins mixed flocks. Song is a short but pleasant and generally descending high-pitched series, typically incorporating whistled and trilled phrases. Call is sharp “tsik-tsik-tsik”, akin to scissors snipping.
Elegant Honeyeater
Meliphaga cinereifrons
A fairly small honeyeater of lowland and foothill wooded habitats. Note the long, slender bill and large yellow ear spot curving around the back of the eye and edged with black. Co-occurs with Mimic, but Elegant is smaller with black around the eye and face spot. Call, a “chup” note like other closely related species but also a thin trill.
Blackish Chat-Tyrant
Ochthoeca nigrita
Small flycatcher endemic to the Venezuela Andes. Plumage is entirely slate gray except for its conspicuous white eyebrows, which can shine like headlights in the gloom. Inhabits cloud forest, and almost always seen near rushing mountain streams. Typical vocalization is a short, descending rasp repeated every few seconds. Formerly lumped with Chestnut-bellied Chat-Tyrant, which only barely reaches over Colombian border into Venezuela and does not overlap with Blackish.
