Purple-crowned Fairy
Heliothryx barroti
Flashy, rather large hummingbird of humid tropical lowlands. Favors forest edges, adjacent clearings with scattered trees and flowering bushes, and gardens. Feeds at all levels, but often in the canopy, hovering with its tail cocked and frequently flashed open to show extensive white. Note the gleaming snow-white underparts, brilliant emerald-green upperparts, and flashy white outer tail feathers. Bill is medium-length, black, and sharply pointed (often pierces flower bases to get nectar). Sexes similar overall, but female lacks purple crown of male, which can be hard to see, and has a longer tail.
Identification
The purple-crowned fairy is 9 to 13 cm (3.5 to 5.1 in) long and weighs about 5.5 g (0.19 oz). It is slender and has bright emerald green upperparts, pure white underparts, and a long pointed tail which has blue-black central and white outer feathers. It has a black patch through the eye and the bill is short, straight, and black. The male has a metallic violet forecrown; the eye patch has a metallic violet spot behind it and bright emerald green below it. The female has a green crown and the face has less black, no violet spot, and no green below the black. Immatures have cinnamon fringes on their upperpart's plumage and the throat and breast have sparse dusky spots.
Taxonomy
The purple-crowned fairy was originally described as Trochilus Barroti. It and the black-eared fairy (Heliothryx auritus) were treated as conspecific by some authors but are now considered to be a superspecies; they are the only members of the genus. Its scientific name commemorates Adolphe Barrot (1801–1870), a French diplomat who served in Colombia from 1831 to 1835. <p>The purple-crowned fairy is monotypic.

Range and habitat
The purple-crowned fairy is found from eastern Chiapas and southern Tabasco in Mexico through the Caribbean slopes of Belize, Guatemala, and Nicaragua; both slopes of Costa Rica; much of Panama; and the Pacific slopes of Colombia, Ecuador, and far northern Peru. In Colombia it also occurs east into the lower valley of the Magdalena River. In elevation it ranges from sea level to 500 m (1,600 ft) in Mexico and northern Central America, to 1,675 m (5,500 ft) in Costa Rica, to 1,000 m (3,300 ft) in Colombia, and to 800 m (2,600 ft) in Ecuador. It inhabits the canopy and edges of humid lowland forest, shady plantations, and mature secondary forest.

Behavior
The purple-crowned fairy is resident throughout its range.<p>The purple-crowned fairy mostly forages in the mid-story and canopy, though at forest edges it will forage lower. It takes nectar from a variety of flowering plants, both by inserting its bill into the corolla and by piercing the base of the flower to "rob" nectar. It also feeds on small arthropods (favoring spiders) by hovering and gleaning from foliage. It does not take insects on the wing like many other hummingbirds. Although it is not particularly territorial, this species is quite aggressive, and will resist the attacks of territorial hummingbird species.<p>The purple-crowned fairy usually breeds between October and March in Costa Rica; its breeding seasons elsewhere have not been documented. The female alone builds the nest, incubates the eggs, and cares for the young. It makes a small conical cup nest of plant down without the attached lichens of many other hummingbird nests. It places the nest near the tip of a thin branch, usually between 6 and 20 m (20 and 66 ft) above the ground and often over water. The clutch size is two eggs. The incubation time is 16 to 17 days with fledging 20 to 24 days after hatch.<p>The purple-crowned fairly is not highly vocal. It does make a call that has been described as "a high, thin, slightly metallic sssit, which may be run into longer rapid series."

Cryptic Becard
Pachyramphus salvini
Small becard occurring from southwest Colombia to northwest Peru, mainly on the west slope of the Andes and in the Marañon drainage, but (perhaps seasonally?) on the east slope of the Andes as well. Mostly found in foothills, in middle to upper levels of humid montane forest, dry forest, and more open second-growth. Male is mostly gray with bold white edges on the wing feathers and a black cap with pale spectacles. Compare with White-winged Becard, which has a black back and dark lores. Female is very different; look for her brown cap bordered with black, white spectacles, pale yellowish belly, and tawny edges on wing feathers. Extremely similar to Black-and-white Becard, with potential range overlap on the east slope of the Andes in Ecuador and Peru. Male Cryptic shows a narrower upper wingbar, paler lores, a grayer upperside of the tail, and a more slender bill than Black-and-white. Female Cryptic has a duller brownish crown with a narrower black border. These features may all be difficult or impossible to assess in the field; some birds are best left unidentified. Also note voice: song a fast series of two sweet downslurred whistles followed by a stuttered upslurred whistle, often repeated two or three times. Black-and-white’s song is slower, with longer notes.
Black-backed Oriole
Icterus abeillei
Attractive orange-and-black oriole endemic to central Mexico, where it takes the place of Bullock’s Oriole (of western North America). Favors open woods, plantations, hedges with tall trees, and towns; migrants also occur in pine-oak forest in mountains. Feeds at all levels in trees and bushes, mixing readily with other orioles. Yellow-orange plumage of male distinct from purer orange of other orioles; also note the big white wing panel, black nape and cheeks, and black flanks. Female very similar to female Bullock’s Oriole but shows ghosting of male head pattern.
Palau Swiftlet
Aerodramus pelewensis
A small, mostly uniformly light brown swiftlet with a slightly darker cap, a cinnamon-tinged throat, and a lightly forked tail. Occurs on larger islands, especially over highland ridges and gorges. Similar to Mariana Swiftlet but much paler, and differs from all other Micronesian swiftlets in its pale rump. Calls are primarily a series of insect-like buzzing and chirping.
