Jamaican Pewee
Contopus pallidus
A small, plain woodland species often found flycatching from exposed perches at middle levels in the forest; often flicks tail once upon landing. Note that this species has relatively inconspicuous wingbars and no eyering. The similar Eastern Wood-Pewee has distinctly longer primaries (assessed by looking at how far the primaries extend beyond tertials), whitish wingbars, and rarely flicks its tail upon landing. The Greater Antillean Elaenia has bold white wingbars and an entirely dark bill unlike the Jamaican Pewee. Vocalizations include plaintive “wee-wee,” with the second note louder and both notes upslurred, a similarly plaintive ‘uh-weee-oo” with the middle portion upslurred, and a slightly rough, whistled “weeah.”
识别特征
The Jamaican Pewee measures 15 cm (5.9in) from bill to tail and weighs 9-9.5g. It has proportionately short wings and long tail with a round body and large head. They also say that the bill is relatively large with the bottom of the bill being orange. The top of the Jamaican pewee is dark-olive toned, while the wings and tail become darker and the stomach is paler. While the male and female birds look similar, the younger birds are grayer on the top and paler on the stomach and beak than the adult birds. The lifespan of the Jamaican pewee is 3.5 years on average.
分类信息
Contopus pallidus was first described by Philip Henry Gosse in 1847. It belongs to the family Tyrannidae. This species used to be seen as conspecific with the Cuban pewee and the Hispaniola pewee, meaning that all three birds were once classified as the same species.<p>The Jamaican Pewee is monotypic.

分布与栖息地
The Jamaican pewee is only found in Jamaica. It can be found on forest edges in mid-elevation across the country, and it can rarely be found in high elevations. There is no distinction for how low Jamaican pewees will fly, but they have been seen to go as high as 2,000 meters. The Jamaican pewee has been seen to fly to lower elevations during the non-breeding season.

行为
The Jamaican pewee perches upright on obvious perches specifically when looking for its prey. It will dive down to grab its prey from the air, returning to the same or new perch, while flicking its tail on the landing.<p>The Jamaican pewee call has a “wee-wee” sound with the second “wee” being louder than the first. Another one of their calls is an “uh-weee-oo” sound where the middle section is more whistled sounding like a “weeah” sound.
保护状况
Jamaican pewees are considered a species of least concern for extinction. The Jamaican pewee population is declining. The population of the bird is suspected to be decreasing because of the ongoing habitat destruction in Jamaica. The extent of the population decrease is unknown.

Golden Palm Weaver
Ploceus bojeri
Breeding male is bright yellow with a mostly orange head. The female is duller, though still very yellow. Both sexes show a dark eye in all plumages. Found in coastal savanna and scrub, often in areas with abundant palms, and inland along rivers through dry country. Similar to African Golden-Weaver, and ranges overlap, but separated by the blackish rather than red eyes. Vocalizations are typical of weavers: “chet” notes and a sizzling “radio static” song.
Silver-breasted Broadbill
Serilophus lunatus
A small, quiet bird with a distinctly silky, smooth-feathered appearance. Shape and pattern unique and unmistakable; note thick black stripe behind eye, dark wings with a glossy blue panel, and broad-based pale bluish bill. Usually moves around through the middle layers of forest from lowlands up into the mountains. Does not often join mixed-species foraging flocks, instead tending to stick to medium-sized groups of its own species. Sometimes gives a smooth, fluid ‘teelee!’
Slender-billed Gull
Chroicocephalus genei
Medium-sized gull with a long, slender bill. Breeding adult has a clean white head and dark red bill, and frequently shows a strong rosy-pink flush to the underparts. Non-breeding adult similar, but may show slight smudge on the head. Immature has orange bill with small brown patches on the wings, most readily seen in flight. Compare with Black-headed Gull; note Slender-billed's longer bill, sloping forehead, and "snouty" profile. Breeds in colonies in inland and coastal wetlands, but restricted to coastal wetlands when not breeding. Away from main range, found singly or in pairs, at times in association with much commoner Black-headed Gull.
