About Ortalis garrula (Humboldt, 1805)
The chestnut-winged chachalaca, scientifically named Ortalis garrula (Humboldt, 1805), measures 53 to 60 cm (1.7 to 2.0 ft) in length. One recorded male weighed 755 g (1.7 lb), and one recorded female weighed 630 g (1.4 lb). Both sexes share the same plumage and skin traits: their upperparts are brown, with lighter coloring 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 boundary between this area and the white lower breast, flanks, and belly. The primary flight feathers are bright chestnut, and bare reddish to black skin surrounds the eye. The chestnut-winged chachalaca is found in northern Colombia. Its range is roughly bounded on the west by the Sinú River, on the east by the foothills of the Sierra Nevada de Santa Marta, and on the south by the lower Cauca and Magdalena River valleys. It lives in a range of landscapes that have thick vegetation, including scrubby deciduous forest, arid scrub, tropical thickets, and mangroves. It avoids the interior of dense forest, but occurs along dense forest edges. Its elevation range extends from sea level to approximately 800 m (2,600 ft).
