Chestnut-winged Chachalaca
Ortalis garrula
Long-tailed, chickenlike bird restricted to the lowlands of northern Colombia. The chestnut wings may be hidden from view when the bird is perched. It can be separated from the similar Rufous-vented Chachalaca by its white belly and pale (not rusty) tail tips. Distinguished from Colombian Chachalaca by lack of scaling on head and breast. Inhabits lightly wooded areas and mangroves. Easier to see early in the morning and late in the afternoon when it often perches up in the open and gives loud, raucous calls.
识别特征
The chestnut-winged chachalaca is 53 to 60 cm (1.7 to 2.0 ft) long. One male weighed 755 g (1.7 lb) and a female 630 g (1.4 lb). Both sexes have brown upperparts that are lighter on the crown and nape; the tail is dark gray-brown with a white tip. The throat and upper breast are also brown with a sharp demarcation between it and the white lower breast, flanks, and belly. The primary flight feathers are bright chestnut. The eye is surrounded by bare reddish to black skin.
分类信息
The chestnut-winged chachalaca was at one time treated as conspecific with the grey-headed chachalaca (Ortalis cinereiceps). It is monotypic.

分布与栖息地
The chestnut-winged chachalaca is found in northern Colombia in an area roughly bounded on the west by the Sinú River, in the east by the foothills of the Sierra Nevada de Santa Marta, and in the south by the lower Cauca and Magdalena River valleys. It inhabits a variety of landscapes characterized by thick vegetation such as scrubby deciduous forest, arid scrub, tropical thickets, and mangroves. It shuns the interior of dense forest but can be found on its edges. In elevation it ranges from sea level to about 800 m (2,600 ft).

行为
The chestnut-winged chachalaca forages in groups of up to eight, generally in trees but sometimes on the ground. In contrast to some other chachalacas, it is quiet as it gleans. Its diet is both fruits and leaves, with more of the former eaten during the rainy season and the latter during the dry season.<p>The chestnut-winged chachalaca breeds during the dry season, between January and April. The nest is a simple platform placed in a tree. The clutch size can be up to four eggs.<p>The chestnut-winged chachalaca is vocal throughout the year (mostly at dawn) but more so during the breeding season. The most commonly heard sound is a duet rendered as "wha-cha-rá" that carries a great distance.

White-bellied Seedeater
Sporophila leucoptera
Small finchlike bird with a short but very strong bill. Males are gray above (black in Bolivia) and white or grayish below with a white patch on the wings. Note the yellow bill. Females are brown above with a paler belly and a dark bill. Found in grasslands with scattered bushes.
Greater Prairie-Chicken
Tympanuchus cupido
Plump, chickenlike bird found in grasslands. Body and wings entirely barred brown with paler buffy throat. In spring, males gather at display site and dance to attract females: look for them hunched over with earlike feathers protruding from the head and yellowish-orange skin exposed on the neck. Inconspicuous and difficult to find away from display sites. Separate from Lesser Prairie-Chicken by range; averages slightly darker and larger than Lesser. Darker than Sharp-tailed Grouse with more heavily barred sides and belly; rounded tail.
Olive Bee-eater
Merops superciliosus
Large green bee-eater with a rufous throat patch. Found in almost any open habitat, including savannah, cultivation, scrub, and grassland. Often perches up conspicuously, singly or in small groups. Feeds on insects on the wing, and often seen in flight, sometimes in loose flocks. Incessantly gives a soft rolling “krrrio” call, especially in flight. Similar in shape and size to European and Blue-cheeked Bee-eaters. Has a very different color scheme from European Bee-eater, and a subtly different one from Blue-cheeked: green underparts, bright white stripes on the cheek, and a brownish crown.
