Antillean Nighthawk
Chordeiles gundlachii
Long-winged nightbird with intricate brown and gray patterning. Very similar to Common Nighthawk, best distinguished by voice. Gives a rapid series of hard, buzzy notes: "drik-rik-rik-rik." A Caribbean species; in the U.S., found only on the Florida Keys. Prefers open areas with mix of grass, bare ground, and shrubs. Nocturnal but can be seen hunting around dawn and dusk, searching for insects in flight.
识别特征
The adults are dark with brown, grey and white patterning on the upperparts and breast; the long wings are black and show a white bar in flight. The tail is dark with white barring; the underparts are white with black bars. The adult male has a white throat; the female has a light brown throat. The most distinguishing characteristic to determine its identity from its closest relative the common nighthawk are the contrasting pale tertials near the back of the wings of a sitting bird. There are two color morphs, a gray and a rufous type. Like other nighthawks, this bird will display by flying upward with a distinctive call note, then diving, pulling out of the dive only a few feet from the ground. This creates a rush of air and distinctive sound.

分布与栖息地
Their breeding habitat is open country of the Greater Antilles, the Lesser Antilles, the Bahamas, and the Florida Keys in the United States. They usually nest on bare ground, sometimes in raised locations including stumps or gravel roofs. They especially favor recently cleared areas in forests, airport fields, cane fields and pastures. Little is known about migration habits, although there is some evidence of migration routes to North and Central South America.

Audouin's Gull
Ichthyaetus audouinii
Elegant slim gull with long legs, and narrow wings. Adults have a light grey body with a paler white head. The wings are light gray with black tips, lacking conspicuous white spots. Legs are dark gray and the bill is dark red. Eyes are dark. Juveniles are similar to Lesser Black-backed Gull, with strongly barred underwings and a U-shaped white rump patch and dark tail. In their 1st winter they develop a gray-brown mantle and in their second winter the head is already white; the tail and secondaries have a black band.
Javan Tesia
Tesia superciliaris
Tiny short-tailed ground-dweller, restricted to foothill and montane forests on Java. Favors areas with dense, tangled undergrowth, in which it bounces around actively. Olive-brown with a gray head and chest. Black line through the eye gives this little bird a strongly “eyebrowed” appearance. Due to size and dense habitat, this tiny warbler can be difficult to track down; listen for its song, a tumbling, jumbled series of beautiful high-pitched notes. Also note call, a dry rattling trill.
Black-headed Mountain Finch
Leucosticte brandti
As gray as the high cliffs, rocky meadows, and glacial moraines it frequents, this mountain-finch is often quite tame and will often take food from monasteries and local highland villages. The dark head and plain body of breeding adults are unique amongst the passerines in its range. Nonbreeding birds are paler-headed, but still retain some of the darkness, especially near the bill, and are less well-marked on the back than Plain Mountain-Finch.
