Buff-winged Starfrontlet
Coeligena lutetiae
Large, long billed hummingbird of the high Andes from Colombia south to far northwestern Peru. Mostly green with obvious buffy wing patch, which is its best ID feature; male has a purple spot on throat, and female has a buffy throat. Found in cloud forest and elfin forest up to near tree line; typically seen in clearings and forest edge, and visits feeders in some areas.
Identification
The buff-winged 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 about 6.6 g (0.23 oz). Both sexes have a long, black, slightly upturned bill and a white spot behind the eye. Both sexes have a forked tail though the female's is not as deeply indented as the male's. Males of the nominate subspecies has velvety black upperparts with a glittering green forehead. They have a violet gorget and the rest of the underparts are dark green. The wings are dark with a large cinnamon-buff patch and the tail is bronzy black. Nominate females have shining dark green upperparts. Their throat is cinnamon-buff and the rest of the underparts golden green with pale fringes on the feathers. They have the same cinnamon-buff wing patch as the males but the tail is bronzy green.<p>Males of subspecies C. l. albimaculata have almost white wing patches but are otherwise like the nominate. Females have a paler throat than the nominate and a cinnamon tinge to the underparts, whose golden green is also less iridescent.
Taxonomy
The buff-winged starfrontlet and most other members of genus Coeligena were at one time placed in genus Helianthea but have been in their current placement since the mid-1900s. The International Ornithological Committee (IOC) and BirdLife International's Handbook of the Birds of the World (HBW) recognize two subspecies, the nominate C. l. lutetiae and C. l. albimaculata. However, the Clements taxonomy treats the species as monotypic.

Range and habitat
The nominate subspecies of buff-winged starfrontlet is found from the Central Andes of Colombia south through the Andes of Ecuador into far northern Peru. C. l. albimaculata is found only in northwestern Ecuador. The species inhabits cloudforest, elfin forest, and the lower edges of páramo. In elevation it ranges from 2,600 to 4,800 m (8,500 to 15,700 ft) but is most common around 3,000 m (9,800 ft).

Behavior
The buff-winged starfrontlet is generally sedentary, though some movement to follow flowering plants has been noted.<p>The buff-winged starfrontlet feeds on nectar by trap-lining, visiting a circuit of flowering plants, but it also will defend patches of flowers. It most often forages at low levels at the margins of forest, and often clings to flowers to feed as well as hovering. In addition to feeding on nectar it captures small arthropods by gleaning from foliage and by hawking.<p>The buff-winged starfrontlet's breeding season in Colombia is August and September; it is not defined elsewhere. It builds a cup nest in a branch fork, typically about 2 to 4 m (7 to 13 ft) above ground. The female incubates the clutch of two eggs for 15 to 17 days; the time to fledging has not been determined.<p>The buff-winged starfrontlet makes a "thin, wiry chatter with rattles", often during territorial disputes. While feeding it often repeats "a characteristic, nasal 'unk'".

Fairy Lorikeet
Charmosynopsis pulchella
A small, long-tailed lorikeet of foothill and lower montane forest. Red head and chest with a darker belly, green back and black patch on the back of the head. Note the yellow undertail and tip, and yellow streaking on the breast. Similar to Josephine’s Lorikeet, but Fairy Lorikeet is distinctly smaller, has streaking on the chest and lacks josephines dark patch on the belly. Call, a soft, high-pitch “seep” note repeated. Sometimes several notes slurred together.
Correndera Pipit
Anthus correndera
A small streaky bird of open habitats from Patagonian steppe grassland to marshes, agricultural fields, and high Andean bogs; widespread and often common. In much of range the only pipit: note boldly streaked plumage, slender bill, and white sides to tail (best seen in flight). In areas with other pipits, note that Correndera has boldly streaked back, often with paler “braces” and strong blackish streaking on flanks; also note voice. Like other pipits, often sings in flight, high overhead.
Numfor Paradise-Kingfisher
Tanysiptera carolinae
A long-tailed kingfisher of forest and gardens on Numfor Island where it is the only paradise-kingfisher. Dark blue body with deep blue crown and shoulder patch, bright red bill and long, white raquet-tail, rump and undertail. Like other paradise-kingfishers, slowly pumps its tail while perched. Song, a rising and quickly accelerating series of nasal notes, starting slowly and ending in a rapid trill “waaaaaak wak ak k-k-k-k-k-k…..”. Pairs fan and raise tail while duetting.
