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.

Little Tern
Sternula albifrons
Tiny, delicate-looking tern. Mainly coastal, but also occurs inland locally. Breeding plumage has black cap with white forehead chevron, black-tipped yellow bill. Readily identified by tiny size, though wintering adults can be confusingly similar in patterning to Common Tern; look out for black stripes extending from the shoulder to the wingtip. Breeds colonially on sandy and stony substrates, at times with other terns, from beaches to riverbanks and lakeshores. Often overlooked unless noisy and mobbing you at a colony. Flies with hurried deep wingbeats; splash dives in water to catch small fish.
Jamaican Blackbird
Nesopsar nigerrimus
A species of higher elevation woodlands where it is often found feeding high in the trees, even near the forest canopy, rather unlike other blackbird species. Indeed, any blackbird found foraging within Jamaica’s upper elevation forests is very likely this species. Its plumage is all black, its tail is short, and the bill is moderately long and slim. The similar Shiny Cowbird has a shorter, stouter bill and a longer tail. The Greater Antillean Grackle is larger, longer-tailed, and has a pale (not dark) eye. The song is a wheezy “whee-whee-oooo” and variations thereof; common call is emphatic, squeaky “wheet.”
Morelet's Seedeater
Sporophila morelleti
Fairly common little bird of grassland and weedy areas in the tropical lowlands and foothills. Occurs from Texas to Panama. Often in flocks, mixing readily with other “weed-eating” small birds. Plumage is very variable, but all birds have a stubby dark bill with a curved culmen. Usually shows two whitish wingbars. Breeding plumage males with a black cap and bold white collar are usually outnumbered by female-plumaged birds, which are plain brownish, sometimes showing buffy wingbars.
