Golden-tailed Sapphire
Chrysuronia oenone
Small hummingbird of humid lowlands. Males are iridescent green with bluish face and rich reddish golden rump and tail; females are similar but lack the blue face and are paler gray below. Usually found around forest edges and oxbow lakes; often one of the most common hummingbirds at feeders in their range.
Identification
The golden-tailed sapphire is 9.5 to 10 cm (3.7 to 3.9 in) long. Males weigh 4.7 to 6.3 g (0.17 to 0.22 oz) and females 4.3 to 5.3 g (0.15 to 0.19 oz). Both sexes of all subspecies have a slightly curved bill with a black maxilla and a black-tipped red mandible. <p>Adult males of the nominate subspecies have a violet-blue head and throat. Their back is bright green that transitions through bronze-green to bright coppery coverts and a copper-bronze tail. Their breast is glittering green, their belly bronze-green, and underneath their tail, their coverts are bronze with whitish edges.<p>Adult females have a blue crown, a green back, and copper-bronze coverts and tail. Their undersides are mostly whitish, with blue-green flecks on the sides of the throat and neck, green on the sides and chest, bronze-green flanks, and underneath their tail, they have bronze coverts. Juvenile males have a dull green crown, a dusky gray throat, and a dull green chest; early adult feathers on the head and throat are a purer, less violet, blue than the adult's. Juvenile females' throat speckles are duller and more bronze-coloured than the adults'.<p>Subspecies C. o. josephinae and C. o. alleni when treated separately have some differences from the nominate and from each other. Males of the former have a mostly green throat and a green rump that contrasts with the coppery coverts. C. o. alleni has an entirely green throat and little blue on the cheeks and its rump is coppery.
Taxonomy
The golden-tailed sapphire was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the golden-tailed sapphire was moved by most taxonomic systems to Chrysuronia. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia.<p>The International Ornithological Committee (IOC) recognizes two subspecies of golden-tailed sapphire, the nominate C. o. oenone and C. o. josephinae. The Clements taxonomy and HBW add a third, C. o. alleni, that the IOC includes within josephinae.

Range and habitat
The nominate subspecies of golden-tailed sapphire is the most widely distributed. It is found in the Serranía del Perijá that straddles the Colombia/Venezuela border, further east in western and northern Venezuela, and south through east central Colombia, eastern Ecuador, and extreme western Brazil into extreme northeastern Peru. C. o. josephinae sensu stricto is found in most of the rest of eastern Peru. C. o. alleni is found in northern Bolivia.<p>The golden-tailed sapphire inhabits semi-open landscapes like the edges and gaps in humid forest, mature secondary forest, gallery forest, shady cacao and coffee plantations, and gardens. In Colombia and Venezuela it ranges in elevation from sea level to 1,500 m (4,900 ft) and in Ecuador between 400 and 1,200 m (1,300 and 3,900 ft).

Tiny Hawk
Microspizias superciliosus
Well-named, this is truly a small hawk, although size can be difficult to judge. Look for fine barring on the underparts, darker cap, and relatively short tail. Adults are gray, juveniles warmer rufous. Lacks a conspicuous collar wrapping around the neck, as in Semicollared Hawk. Not frequently seen; often stays inside forests, where it hunts small birds. Sometimes perches at the forest edge. Almost always seen singly.
Pale Cicadabird
Edolisoma ceramense
Male is a pale ashy-gray songbird with darker, pale-edged wings. Female is paler, especially underneath, and shows more extensive pale wing markings. Juvenile is still paler than female with faint breast streaking. Found in a variety of woods and forests in lowlands and foothills, where singles, pairs, or groups inhabit upper levels. Smaller than Black-faced, Moluccan, and Buru Cuckooshrikes, with a noticeably slimmer bill and much less black on the head. Differs from Wallacean Cuckooshrike in its paler appearance and in showing less black on face. Calls include a dry rattle, “grrrrrrrt,” a short single “chuck” call, and chattering phrases.
Ayacucho Thistletail
Asthenes ayacuchensis
Poorly known thistletail found only in a small area of the high Andes east of the city of Ayacucho in southern Peru. It is brown above, gray below, with a long wispy tail and a reddish-orange chin patch. It has a darker chin patch than Vilcabamba Thistletail and Puna Thistletail, and is not known to overlap with either species. It inhabits scrub and stunted forest near treeline. Song is a rapid, high-pitched trill.
