行为
The red-headed barbet's diet has not been studied in detail, but it is known to include arthropods such as caterpillars and adult insects and fruit such as berries and (at feeders) bananas.<p>Little has been published about the red-headed barbet's breeding phenology. Like other New World barbets, they excavate cavities in trees and sometimes in fence posts. The clutch size is two to five; the female incubates at night and both sexes do so during the day.<p>The red-headed barbet's song has been described as "a resonant, ventriloquial, somewhat toad-like trill krrrrrrrrrrr" [1]. Some calls have been described as "grunts and snarls" [2].

Red-legged Brushturkey
Talegalla jobiensis
A large, black ground bird of rainforests from the lowlands to mid-mountains. Red-orange legs stand out against the all black plumage. Bare face and a bushy feathers on top of the head give it a crested appearance. Often hammers seeds with its strong bill. The red-orange legs separate it from any similar-sized birds with which it co-occurs. Much more often heard than seen. Loud raucous call, similar to Red-billed Brushturkey but the second note rises higher.
Madagascar Ibis
Lophotibis cristata
A rather fantastical forest-dwelling ibis with a colorful face, white wing, and rich brown body. Endemic to Madagascar, where it is most frequently encountered in eastern rainforest, though it also occurs locally in western deciduous forest. Roosts and nests in trees, and feeds on the forest floor. Extremely shy, and unless spooked will rapidly flee from disturbance on foot. Very loud and vocal, giving a long and agitated series of wheezy, whining notes. Calls most often at dawn and dusk and during the night.
Barred Antshrike
Thamnophilus doliatus
A retiring bird of thickets, forest edge, and other tangled vegetation. Distinctive song is heard regularly and pairs are usually within earshot of each other, but antshrikes generally remain hidden. The sexes look very different, but both have a spiky crest that is often raised. Male is barred black-and-white in ‘convict stripes,’ whereas female looks a lot like a wren with a stout bill that has a slightly hooked tip.
