Barbetto dal mantello bianco

Identificazione

With the division of toucan barbet, the white-mantled barbet is perhaps the largest of the New World barbets, rivaled only by the scarlet-banded barbet. with an average length of 19 cm (7.5 in), males and females respectively weigh an average of 74.6 g (2.63 oz) and 67.4 g (2.38 oz). The bird has black upperparts with narrow pale lines on the nape and scapulars. These lines are not easy to see because the bird is mostly observed higher up in the canopy of tall trees. The forehead and crown are red. The bird's underparts are white with a slight yellowish wash and a flush of cinnamon on the breast. They eyes are red, the large, chunky bill is yellowish, and the legs and feet are greenish-grey. Females have a black spot at the base of the lower mandible.

Comportamento

These barbets typically forage in pairs or family groups, and may follow mixed-species feeding flocks. They mostly stay in the forest canopy, but come down and into the open at fruiting trees such as mango and Cecropia.<p>The white-mantled barbet population is declining, primarily due to habitat loss. The IUCN Red List classifies the species as vulnerable. The Red Book of the Birds of Colombia, noting that the species has lost 60% of its historic habitat and that that habitat continues to decrease, lists the bird as endangered. The primary causes of this habitat loss are illicit cultivation, overuse of insecticides, and small-scale gold mining.
