Plumbeous Pigeon
Patagioenas plumbea
Large dark pigeon of forest interior. Overall purplish-gray, slightly darker and browner on wings. Pale eye. Sexes alike. Note plainer appearance and longer tail than many other doves and pigeons. Most similar to Ruddy Pigeon but plumage grayer (not reddish) and eye paler. Usually quite secretive, staying in the canopy where singles or pairs feed on fruits. Found from lowlands into subtropical zone, up to 2,300 m (7,500 ft). More often heard than seen; listen for the cooing “who-cooks-for-you” song with the last two notes drawn out.
识别特征
The plumbeous pigeon is 34 cm (13 in) long and weighs 172 to 231 g (6.1 to 8.1 oz). Males have a dark gray head, neck, and underparts that sometimes have a pinkish or purplish tinge. The shoulders, back, rump, wings, and tail are dark grayish brown to drab olive. The hindneck sometimes has bronzy spots. The eye is red and surrounded by bare purplish red skin. The female's purplish wash is less intense and the neck spots more intense than the male's. Juveniles are duller than the adults, with very little purplish wash, and some feathers have rusty edges. The subspecies differ mostly in the amount and intensity of the pink or purple on the upperparts. Visually the plumbeous pigeon can be confused with the ruddy pigeon (P. subvinacea) where their ranges overlap, but their vocalizations are very different.
分类信息
The plumbeous pigeon is most closely related to the ruddy pigeon (P. subvinacea), short-billed pigeon (P. nigrirostris), and dusky pigeon (P. goodsoni), and they have sometimes been placed in subgenus Oenoenas. These six subspecies are recognized:<p>Vocal differences among and even within the subspecies hint that more than one species may be involved.

分布与栖息地
The subspecies of plumbeous pigeon are found thus:<p>The plumbeous pigeon inhabits tropical and subtropical rainforest and cloudforest, both primary and secondary. North of the Rio Orinoco it is found between 1,200 and 1,900 m (3,900 and 6,200 ft) of elevation but south of there only between 200 and 300 m (660 and 980 ft). In southeastern Brazil it makes seasonal altitudinal migrations.

行为
The plumbeous pigeon forages in the forest canopy for fruit and seeds. In Brazil it feeds heavily on mistletoe drupes at some times of the year.<p>The plumbeous pigeon's breeding phenology has not been studied.<p>The general pattern of the plumbeous pigeon's song is "a repeated rhythmic phrase of 2–5 coos" and the call is "a purring, drawn-out, slightly overslurred 'rrrrrow'." There are at least five distinct vocal groups whose songs are variations on the general pattern.

Senegal Parrot
Poicephalus senegalus
Chunky mid-sized parrot with a green back and breast, a gray head, and a colorful belly that shows some geographical variation from yellow to reddish-orange. Found in all types of savanna, including broadleaf savanna, dry thorn savanna, and human-created savanna in the forest zone. Calls are variable sizzling screeches, often given in flight. Similar to Niam-Niam and Meyer’s Parrots, but separated from both by the yellow-orange belly.
Yellow-necked Spurfowl
Pternistis leucoscepus
A large brown francolin with yellow bare skin on the throat and red bare skin around the eyes. The bill and legs are black. Pale patches in the outer wings are conspicuous in flight. Found in a variety of fairly arid savanna habitats and in adjacent agricultural fields. Usually in pairs or small groups. Easily separated from other francolins by its bare yellow throat. The call is a fading series of rough “kreaaak” notes.
Caribbean Martin
Progne dominicensis
A graceful aerial feeder found over a wide variety of open habitats, especially near water, including marshes and towns. Often seen on exposed perches including power and telephone lines in villages. Commonly found in flocks of up to twenty birds, sometimes mixing with other swallows and martins. Note the male’s diagnostic glossy purple-blue plumage and snow-white belly. Females and immatures are similarly patterned, but have brown mixed with the blue and are probably not safely separable from Cuban Martin. Female and immature Purple Martins are very similar, but they often have a scaly breast and finely streaked belly, with less contrast between belly and chest. Notably, Cuban and Purple Martins are not present in this species’ range from March to September. Calls include a harsh “churr,” a buzzy “zwick-zwick,” and a musical buzzy burbling.
