    Chauna – South America screamers

    These talented birds can produce the sound of a trumpet as well as a drum

    Screamers are geese-like birds that can walk and swim. They have robust legs, and between their lengthy toes is still a relic of a vestigial web.

    The adult Screamer has grey plumage: Grey upper parts, dark grey wings, and a dark grey tail. Coverts have a buffy-white edging across the edges of their wings, giving them a scaled appearance.

    The Screamer makes deafening calls, which it typically does while flying. They may be heard from a distance of 3 kilometers (2 miles). They call at all times of the year. They have loud voice that sounds like trumpets. Other noises produced by Southern Screamer include guttural screaming and drumming.
