Hook-billed Kite
Chondrohierax uncinatus
Widespread raptor of tropical America, occasionally reaching as far north as southern Texas. It can be identified in all plumages by its fiercely hooked bill and yellow or orange spots on face and bill. In flight, note the blunt, bulbous wings, strongly barred flight feathers, and broad tail bands. Male is mostly gray with faint white or tan barring on the underparts. Female has a brown collar and brown and white barred underparts; the pattern and color vary somewhat throughout its range. Juvenile is mostly white below with very sparse barring. Common call is a quick, shrill cackle. Inhabits both dry and humid forest at all but the highest elevations, and often seen soaring with other raptors or vultures.
识别特征
It is a mid-sized, slender raptor with an invariably striped belly and banded tail but there is probably more individual variation in color and in size of bill than in any other species of diurnal raptor. Birds from beneath can look blackish or gray (especially males) and brown or brick-red (females) variously. This renders species identification at times extremely difficult. The downcurved hook at the tip of the beak is apparent on perched and low-flying birds. Weight can range from 215 to 397 g (7.6 to 14.0 oz) and length is 38–51 cm (15–20 in).
分类信息
The critically endangered Cuban kite (C. wilsonii) is considered by some authors to be a subspecies of the hook-billed kite.

行为
Tree snails (e.g. Bulimulus, Homolanyx, and Polymita) are a vital component of the hook-billed kite’s diet. The density of their population within a region is proportional to the presence of tree snails. It has also been observed that the beak of the hook-billed kite has adapted in size and shape between different regions of their territory in response to the species of tree snail available to them. However, terrestrial snails (e.g. Strophocheilus), aquatic snails (e.g. Pomacea), frogs, salamanders, lizards, small mammals, crabs, spiders, caterpillars, and insects are also taken. It supposedly also hunts other birds, but this seems unlikely. When it finds a tree snail it holds it with its talon and uses its beak to pry open the shell.

Fire-bellied Woodpecker
Chloropicus pyrrhogaster
A large, long-billed woodpecker with an olive back, a red rump, a bold facial pattern, and heavily marked underparts with a bright red central belly stripe. The crown and back of the head are black in the female and red in males. Forages alone or in pairs, preferring dead tree trunks where it can excavate for beetle larvae and other insects in lowland rainforest, gallery forest, and plantations. Calls include a sharp “kwip,” a series of similar notes, and a fast whinnying call. Also gives a distinctive drum that lasts about 2 seconds, beginning fast and then slowing. Similar to Bearded and Yellow-crested Woodpeckers, but there is very little overlap in range, and those species lack the red belly patch.

Nepal House-Martin
Delichon nipalense
A typical house-martin, with dark upperparts, white underparts, a white rump, and a rather dumpy body. Differs from Common and Asian House-Martins by its sooty throat. Upperparts can have a bluish gloss if seen in good light. Breeds on ridges and cliffs, and occasionally around human settlements. Associates with other swallows and swifts, often gathering over water to catch emerging insects.

Black Berrypecker
Melanocharis nigra
A small, common bird of lowland and foothill forest. Fairly slender with a black bill. Male plumage varies geographically but all have black head, back, tail and a white side tuft. Underparts are gray or black, and wing is olive or black. Female is mainly olive with a slightly paler underparts. Similar to Obscure and Mid-Mountain Berrypeckers, but Black has a shorter tail than Mid-Mountain and lacks the orange bill of Obscure. Voice, a repeated, scratchy “witoo-chii!” ending on a high note.
