Fiery-tailed Awlbill
Avocettula recurvirostris
A small, uncommon hummingbird with a peculiar bill. Male appears mostly dark green, whereas female is green above and white below with a black line down center of breast. Bill is short, straight, and upturned at the tip. Found locally in drier habitats including savanna, forest edge, and dry zones on large granite outcrops, where it is most frequently seen around flowering trees or perched on bare branches. Feeds on nectar and hawks for insects either in hovering flight or from perches. Best told from other hummingbirds by distinctive bill; in plumage both male and female resemble respective sexes of Black-throated Mango, but awlbill is much smaller with.

分布与栖息地
The fiery-tailed awlbill is found in Amazonia, from southeastern Venezuela east through the Guianas into northern Brazil and south into Brazil as far west as Acre and as far east as Maranhão and Tocantins. There is also a disjunct population along the Napo River in eastern Ecuador. The species has been recorded as a vagrant in Colombia.<p>The fiery-tailed awlbill primarily inhabits open savanna-like areas in primary forest where it favors vegetation near granite outcrops. It can also be found at the edges of low vegetation near rivers, semi-deciduous forest, and cerrado.

行为
The fiery-tailed awlbill is believed to be sedentary.<p>The fiery-tailed awlbill is a "trap-line" feeder, visiting a circuit of flowering plants to collect nectar. It favors Clusia and Dioclea shrubs, and feeds both by inserting its bill into flowers and by piercing the base of flowers to "rob" nectar.It also catches arthropods on the wing and by gleaning from the underside of leaves.<p>The fiery-tailed awlbill's breeding season varies across its range. It is known to span from September to December in Suriname and there are records from July in northern Brazil and French Guiana. The female builds a small cup nest of soft plant materials and spider silk on a horizontal branch, usually between 5 and 12 m (16 and 39 ft) above the ground. The female alone incubates the clutch of two eggs.<p>The fiery-tailed awlbill's song has not been recorded. Its call is "a series of 'tsik' notes" and is given in flight or while hovering.

Black-vented Oriole
Icterus wagleri
Attractive oriole of the interior and highlands; some migrate in winter to Pacific coast lowlands. Favors scrubby woodlands and semiopen areas with tall hedges of flowering trees; also flowering coconut plantations on the Pacific coast. Usually in pairs; found as often apart from other orioles as mixed with them. Sexes alike: yellow breast has a distinctive, burnished orange tone. Upperparts appear wholly black when rump is covered by wings. Black vent area diagnostic on adult. Immature variable: note lack of wingbars, orange tones to yellow plumage, and rather long, straight bill.
Olive-headed Greenbul
Arizelocichla striifacies
Large chunky, olive-green greenbul. There is geographic variation in the color of the eye (pale or dark) and the amount of yellow on the underparts. Throughout the range, shows a dark cheek with diagnostic fine pale stripes, though a good look is required to see these. Found in humid foothill and montane forest. Often joins mixed flocks with other birds. The song is a chatty, up-and-down series of low “chowp” notes and higher nasal notes. Similar to mountain greenbuls, but always separated by the more distinct cheek striping.
Kauai Elepaio
Chasiempis sclateri
A small flycatcher of forested habitats on Kauai. Adults have a gray back and white wingbars, while immatures are reddish brown with buffy wingbars. Common in native forest at higher elevations. Bold and curious; not afraid of people and may follow hikers. Often holds tail cocked up at an angle. Male song consists of two notes that rise and fall and have a squeaky, rubber ducky quality. Both sexes give a variety of soft calls and scolding notes. Responds to pishing and squeaking.
