Bare-eyed Pigeon
Patagioenas corensis
Large, pale pigeon, unmistakeable if seen well, with large pale blue ocular ring and prominent white wing patches. Occurs in pairs or in small to large groups; mainly seen in trees, tops of cactuses, or in flight. Locally common in desert scrub, dry forests, and mangroves. Voice a very low “cooooo, tuk-tu-kUUuu, tuk-tu-kUUuu,” similar to other pigeons. The only pigeon with white wing patches in arid regions in its range.
识别特征
Male bare-eyed pigeons are 32 to 37 cm (13 to 15 in) long and females 30 to 34.5 cm (11.8 to 13.6 in). They weigh about 274 g (9.7 oz). Male and female plumage is the same. Their head, neck, and breast are mauve-pink. The orange-brown eye is surrounded by bare skin, a narrow blue ring and a wider outer area of reddish brown. The neck and upper back have a bronze-black and pale brown scaled appearance and the lower back and rump are pale bluish gray. The chin and vent region are white. The closed wing shows a broad white patch. The juvenile is a paler version of the adults.
分类信息
At least one author has asserted that based on plumage similarities the bare-eyed pigeon, picazuro pigeon (P. picazuro), spot-winged pigeon (P. maculosa), and scaled pigeon (P. speciosa) form a monophyletic group. Others argue that significant vocal differences belie that.<p>The bare-eyed pigeon is monophyletic.

分布与栖息地
The bare-eyed pigeon is found on the Caribbean coasts of Colombia and Venezuela and the near-shore islands of Aruba, Curaçao, Bonaire, Margarita, and Blanquilla. It primarily inhabits an arid landscape of thorn scrub, cactus, and acacia and is also found in mangroves and cultivated areas. It can be found as high as 400 m (1,300 ft) above sea level on the mainland but is generally much lower.

行为
The bare-eyed pigeon does most of its foraging in trees and shrubs but also feeds on the ground. Its diet is seeds and fruits of trees, vines, and cultivated crops.<p>The bare-eyed pigeon's breeding cycle appears to be triggered by rain. The nest is a fragile platform of twigs in a tree or shrub. It is so thin that the species' single egg can be seen through it from below.<p>The bare-eyed pigeon's song is "a rhythmic series of coos...rwhoh...woh-hu-whOAh...woh-hu-whOAh..woh-hu-whOAh...".

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.
Rufous-backed Sibia
Leioptila annectens
Ebony head and snowy throat, combined with the hazy mixture of bright orange and black on the back, give this bird a distinctly “tortoiseshell” appearance. Appears larger-headed and slightly shorter-tailed than other sibias. Inhabits foothill and montane forests, where it travels in pairs and flocks through the canopy. Unlike other sibias, frequently clambers around on tree trunks and branches like a nuthatch. Listen for its lovely warbled song and buzzy chattering calls.
Common Sandpiper
Actitis hypoleucos
Small bicolored sandpiper which often bobs its tail in a distinctively wagtail-like manner. Plain brown with white underparts; distinguished from bulkier and rounder-headed Green Sandpiper by a prominent white spur at the shoulder. Found in a variety of wetland habitats; breeds on stony ground along rivers and lakeshores, with migrants occurring on muddy and rocky substrates from concrete canal banks to channels in tidal mudflats. Mainly found as singles or in small groups, not in flocks or mixed with other species.
