Green-throated Carib
Eulampis holosericeus
This large hummingbird has a somewhat down-curved bill. Though iridescent green, it appears black in mediocre to poor light. Most easily distinguished from Purple-throated Carib by its dull wings (wings are iridescent green in Purple-throated) and less curved bill. Common in much of its range, where it frequents forests but also visits gardens and parks. Calls include “chewp” and a variety of twitters.
识别特征
The green-throated carib is a large hummingbird, 10.5 to 12 cm (4.1 to 4.7 in) long. Both sexes have a bright green back, though the female's is duller, and a bright green gorget. The male's gorget has a blue border that is usually not apparent. Males and females have a black belly, a green vent area, and a dark blue tail that appears black in poor light. The underparts of subspecies E. h. chlorolaemus are somewhat darker than those of the nominate. Males have a medium length slightly decurved bill; the female's is longer and more strongly curved.<p>The calls include a sharp chup! or chuwp!. During territorial disputes it sometimes makes rattles and whirs with its wings.
分类信息
The green-throated carib was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Trochilus holosericeus. Linnaeus based his description on the "black-belly'd green huming bird" that had been described and illustrated by the English naturalist George Edwards in 1743. The type locality is the Lesser Antilles. The specific name is from the Ancient Greek holosērikos meaning "silken". The green-throated carib is now placed in the genus Eulampis that was introduced by the German zoologist Friedrich Boie in 1831 and which it shares with the purple-throated carib (E. jugularis).<p>Two subspecies are recognized, the nominate E. h. holosericeus (Linnaeus, 1758) and E. h. chlorolaemus (Gould, 1857).

分布与栖息地
The green-throated carib is generally sedentary but some are known to move to wetter areas after the breeding season. The nominate subspecies is found from eastern Puerto Rico through the Virgin Islands and the Lesser Antilles chain as far as (but not including) Grenada. E. h. chlorolaemus is endemic to Grenada. The species inhabits a variety of landscapes including wet forest, semi-deciduous forest, cultivated areas, gardens, and parks. On Martinique it is also found in drier habitat. On many islands it is most common near sea level though on Dominica it is found mostly in foothills.

行为
The green-throated carib feeds on the nectar of a variety of flowering shrubs and trees. Males are believed to defend flowering feeding territories all year but females do so only in the non-breeding season. The species also feeds on small arthropods such as insects and spiders, mostly caught on the wing.<p>The green-throated carib is believed to nest between March and July, and might depend on the timing of rain. Its nest is a cup lined with soft fibers and has lichen and bark chips attached to the outside. It is usually placed in the fork of a branch 2 to 9 m (7 to 30 ft) above the ground. The clutch is two eggs. The incubation time is 17 to 19 days with fledging 20 to 22 days after hatch. Birds first breed in their second year and may nest twice in a year.

Swallow-tailed Manakin
Chiroxiphia caudata
A very common inhabitant of humid forests. Small chunky manakin with elongated central tail feathers. Males are unmistakable with their blue bodies, black wings and head, and red crown. Females are uniformly green with a dark eye and pale legs and bill. Very noisy at the display lek where males can be heard from a long way off delivering soft “kua-a-a-a” notes.
Stripe-necked Tody-Tyrant
Hemitriccus striaticollis
A small, relatively drab flycatcher found locally across its wide range. Primarily yellowish in plumage, brightest on the belly. Whiter throat has strong grayish stripes blending into blurrier streaks on the chest. Generally found in scrubby semi-humid habitats, and often likes viney tangles. Where overlaps with the similar Johannes’s Tody-Tyrant, note the stronger throat markings and generally brighter overall coloration.
Lyre-tailed Honeyguide
Melichneutes robustus
A large canopy honeyguide that is far more often heard than seen, although it does sometimes descend lower, almost to ground level. When seen, its greenish upperparts contrast with its pale olive underparts to give it a two-toned appearance. Belly is pale with flank streaking, and the distinctive tail has white edges and feathers that curve outward, giving it a lyre shape that is most noticeable in the males. Males perform aerial displays high overhead in which they quickly open their wings and tails to create a two-parted sound like a bow on a string that gradually grows louder, “huhwa, huh-wa, HUH-WA.” Despite its distinctive displays, the bird can be frustratingly difficult to locate and see.
