Bahama Mockingbird
Mimus gundlachii
An often conspicuous resident of a wide variety of habitats including woodlands, scrub, and suburbia. Its long, white-tipped tail and largely gray plumage eliminate all other species except for Northern Mockingbird. Unlike Bahama, the Northern Mockingbird has large white patches on wings (most easily seen in flight), white outer tail feathers, and is unstreaked below, except in immature plumage. Streaking on young Northern Mockingbirds is mostly on chest, not concentrated on sides, as it is in the Bahama Mockingbird. Song is a series of phrases, each repeated several times; contrary to its name, it does not mimic other species.
识别特征
The Bahama mockingbird is 28 cm (11 in) long and weighs between 57 and 85 g (2.0 and 3.0 oz) with an average of 66.8 g (2.36 oz). Adults of the nominate subspecies have a mottled face with a pale supercilium. Their upperparts are brownish gray with dark streaks from the crown to the lower back. Their outer tail feathers have whitish tips. Their underparts are light gray with light streaking on the upper breast and more prominent streaks on the flanks. The juvenile is similar but has more densely spotted underparts. M. g. hillii has more prominent streaking on its back than the nominate and the white tips on the tail feathers are larger.

分布与栖息地
The nominate subspecies of Bahama mockingbird is found in the Bahamas, the Turks and Caicos Islands, and the Sabana-Camagüey Archipelago off Cuba's north coast. M. g. hillii is found only in southern Jamaica.<p>Except in Jamaica, the Bahama mockingbird inhabits a variety of biomes including coastal strand, semi-arid scrub, open woodland, and plantations. In Jamaica it inhabits dry scrubby woodland on limestone hills. It appears to favor taller, denser vegetation than the similar northern mockingbird (Mimus polyglottus) where their ranges overlap.

行为
The Bahama mockingbird is omnivorous; its diet includes invertebrates, nectar, small fruits, and small lizards. It mainly forages on the ground, searching through leaf litter, but also hunts up to 6 m (20 ft) high in vegetation. It aggressively defends feeding sites.<p>The Bahama mockingbird's breeding season spans from February to July in most areas but from April on the Cuban islands. Both sexes build a rough open cup nest of twigs, lined with softer fibers, and usually placed low in a bush. They aggressively defend their territory with vigorous song. The clutch size is two or three.<p>The Bahama mockingbird's song is loud and repetitive, a "series of abrupt, varied notes and phrases, with repetition". It apparently does not mimic other birds' songs.

Pale-breasted Illadopsis
Illadopsis rufipennis
A chunky, mid-sized, remarkably drab babbler with a white throat and brownish breast. Found in the understory of rainforest at low and middle elevations, usually in small groups. Shy and skulking; rarely seen unless searched for. Very similar to Brown Illadopsis, but slightly different vocally, with higher and more inflected whistles. Also slightly paler below and more richly colored above, with a cleaner white throat. Most often detected by voice. The highly variable song consists of single-note pure whistles or short whistled phrases separated by pauses, often in a three-note ascending series; listen for a haunting clear monotone whistle. Also gives scolding calls, sometimes accompanying the whistled song.
Burrowing Owl
Athene cunicularia
Small, long-legged owl of open grassy habitats. Appears brown at a distance with irregular white spotting. Yellow eyes. Typically found on the ground or perched on low fence posts or rocks. Active during day and night when it hunts mainly for insects and small mammals. When agitated, it stands erect and abruptly bows down. Nests in a burrow, often dug by a prairie dog or tortoise.
Masked Fruiteater
Pipreola pulchra
Chunky green bird with a broad, blunt bill. Males have a bright orange bill, a blackish face, a yellow-orange necklace that bleeds into the breast, and a yellow lower belly; females are nearly entirely green with faint streaking below and a dull orange bill. Notice the females’ dull olive legs and streaked, not scaled pattern underneath, which distinguish it from the similar, orange-legged female Scarlet-breasted Fruiteater. Perches inconspicuously in the mid-story of humid montane forest, where it is often found around fruiting trees and occasionally joins mixed-species flocks.
