Сивокрил тръбач Psophia crepitans

Chicken-sized and oddly proportioned terrestrial bird of tall rainforest that is common where not hunted. Peculiar shape, behavior, and tendency to occur in large groups render this species difficult to mistake for any other. Groups walk through forest, flicking wings nervously while feeding on insects, small vertebrates, and fallen fruit. Often seen crossing roads through forested regions. Can be extremely noisy, especially when startled; bizarre calls include a variety of grunts, wails, and screams.
