Antillean Piculet
Nesoctites micromegas
A tiny, chubby woodpecker that frequents a wide variety of wooded habitats including mangroves. More prone to feed on small branches, even vines, than are larger woodpeckers. Olive-brown above and streaked below, unlike any other species in its range. Male has red on crown that female lacks. Its call is a loud burst of rapid liquid chatter.
识别特征
The Antillean piculet is 14 to 16 cm (5.5 to 6.3 in) long and weighs 26 to 33 g (0.92 to 1.2 oz). It is the largest piculet, and is about double the size of the Neotropical piculets of genus Picumnus. Adult males of the nominate subspecies have a lemon yellow crown with an orange-red to red patch in the center. Their hindneck is yellowish green and their upperparts dull olive green to yellow-green with a faint rusty-bronze tinge. Their wings are olive green and the flight feathers have yellow-green edges. Their tail is browish olive with a bronze cast. Their cheeks are dull whitish with olive barring, their chin and throat white with a faint yellow tinge, and the rest of their underparts pale yellowish white. The throat has a few small dark spots and the breast and belly have wide dark streaks. Adult females are larger than males and have the same plumage except without the red crown spot. Juveniles are overall duller than adults, do not have a red crown spot, and have obscure barring rather than streaks on their underparts. Subspecies N. m. abbotti is paler than the nominate and has less yellow on the crown, grayer upperparts, a plainer white throat, and less heavy streaks on the underparts.
分类信息
The Antillean piculet is the only member of genus Nesoctites. The species is evolutionarily distinct from the other piculets, and some taxonomists afford it its own subfamily Nesoctitinae. A fossil feather in amber attributed to the genus has been found in the Dominican Republic, showing that the ancestors of the species have been isolated on Hispaniola for at least 25 million years.<p>The Antillean piculet has two subspecies, the nominate N. m. micromegas (Sundevall, 1866) and N. m. abbotti (Wetmore, 1928).

分布与栖息地
The nominate subspecies of Antillean piuculet is found throughout the main island of Hispaniola. N. m. abbotti is restricted to Gonâve Island off the west coast of Haiti. The species inhabits a variety of landscapes including humid and dry broadleaf forests, Hispaniolan pine forests dominated by Pinus occidentalis, semi-arid scrubland, and thorn forest. It also occurs in mangrove forest and occasionally in orchards and plantations. In all habitats it favors dense undergrowth. In elevation it is most numerous between about 400 and 800 m (1,300 and 2,600 ft) but occurs as high as 1,770 m (5,800 ft) in Sierra de Bahoruco of southwestern Dominican Republic.

Little Forktail
Enicurus scouleri
A stout little sprite of rushing streams, the smallest of the forktails and the only one lacking a long tail. Adult black with a white forecrown, belly, rump, and wing patches. Juvenile similar but grayer overall and lacks white crown. Approachable and active, though surprisingly easy to lose among the shadows and spray of its preferred habitat.
Magpie Mannikin
Spermestes fringilloides
Large waxbill with a big bill. Shows a black head, brown back, and black scallops along the sides of the breast. Found in bamboo, moist scrub, moist cultivation, lush savanna, and forest edge. Quite scarce across most of its range. Call is a descending “teeiw”. Superficially similar to Bronze Mannikin but larger and bigger-billed, with an all-black head and distinctive scallops along the breast sides.
Mountain Grackle
Macroagelaius subalaris
Scarce blackbird found only at higher elevations in the northern half of Colombia’s eastern Andes. It is quite slender and nearly all black, but has a maroon patch under the shoulder which is mostly hidden from view when the bird is perched. The dark bill and eye help to separate it from other similar species if the wing patch is not visible. Usually seen in the forest canopy and may congregate in large flocks. Song is a chaotic series of sharp, shrill notes mixed with clacking calls.
