Purple Honeycreeper
Cyanerpes caeruleus
Very small tanager, widespread and common in lowlands and foothills of northern South America. Male is indigo-blue with narrow black mask, black throat, and black wings. Note long decurved bill and yellow legs to separate from other honeycreepers in most of range. Female much different: she is mostly green with pale streaking on underparts, a grizzled buffy-brown face, and a blue mustache stripe. Extremely similar to Shining Honeycreeper, but very little range overlap. Male Shining has larger black throat patch and slightly shorter bill; female has duller, grayer crown and less buffy face. Usually in small groups, often accompanying a mixed-species flock in the canopy. Found in forests, edges, and gardens.
识别特征
The purple honeycreeper is 4.5 in (11.5 cm) long, weighs 0.42 oz (12 g) and has a long black decurved bill. The male is purple with black wings, tail and belly, and bright yellow legs. Females and immatures have green upperparts, and green-streaked yellowish-buff underparts. The throat is cinnamon, and there is a blue moustachial stripe. The call of purple honeycreeper is a thin high-pitched zree. The Trinidadian subspecies C. c. longirostris has a longer bill than the mainland forms.
分类信息
The purple honeycreeper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Certhia carrulea. Linnaeus based his description on "The Blue Creeper" that had been described and illustrated in 1743 by the English naturalist George Edwards from specimens collected in Suriname. The specimens had been mounted in glass cases and were owned by the Duke of Richmond. The purple honeycreeper is now placed in the genus Cyanerpes that was introduced in 1899 by the American ornithologist Harry C. Oberholser. The specific epithet caeruleus is Latin for "dark blue".<p>Five subspecies are recognised:

分布与栖息地
The species is a bird of northern South America, and besides the Amazon Basin and the Guianas, a coastal range occurs west of the Andes, including parts of southern Panama. In the south, its range extends to the extreme western Pantanal. Though it is most frequently seen in the lowlands up to 3,300 ft (1,000 m) ASL or so, it has been encountered as high as 7,500 ft (2,300 m) ASL.<p>This is a forest canopy species, but also occurs in cocoa and citrus plantations. At the upper limit of its altitudinal range, it frequents premontane rainforest, usually rather low-growing (33–50 ft/10–15 m) and full of epiphytes and mosses, and even elfin forest and páramo.

行为
The purple honeycreeper is often found in small groups. It feeds on nectar (particularly from bromeliad and similar flowers, to which its bill shape is adapted), berries and seeds (i.e., Trema and Clusia), fruit (i.e., bananas and papayas) and insects, mainly in the canopy. It is a bold and inquisitive bird, responding readily to the call of the ferruginous pygmy owl (Glaucidium brasilianum) by coming out of cover and searching for the presumed predator to mob it. The female purple honeycreeper builds a small cup nest in a tree, and incubates the clutch of two brown-blotched white eggs.

Bar-bellied Woodpecker
Dryobates nigriceps
Small woodpecker found in high elevation Andean forest. Both sexes have olive back and wings, dense barring on underparts, and white stripes on the face. Male has red crown and female has black crown. Similar to Yellow-vented Woodpecker but barring extends to belly and vent. Feeds at all levels in the forest, and sometimes joins mixed-species flocks.
Banda Myzomela
Myzomela boiei
A small honeyeater with a downcurved bill. Striking male has a candy-apple red hood, back, and rump, contrasting with the black wings, tail, and chest band and the white belly. Female is uniform gray-brown except for a diagnostic faded red wash on the face and throat. Singles or pairs inhabit lowland forests, forest edge, mangroves, and open wooded areas, sometimes joining mixed-species flocks. Unmistakable, as it is the only myzomela in its restricted range in the Banda Islands. Song comprises several introductory notes followed by a rapid warble: “chi-chi-churrrrrrrr.”
Pink-legged Graveteiro
Acrobatornis fonsecai
Predominantly gray species with a long tail and pink legs. Note the darker gray crown and paler eyebrow. Found principally in shaded cacao plantations or adjacent remnant forests across a very restricted range. Forages acrobatically in the canopy and subcanopy and often accompanies mixed-species flocks. Builds a large stick nest.
