coscoroba swan

The coscoroba swan is the smallest species of swan. Loud, trumpet-like sounds are produced by special structures in their throat.

Coscoroba swans feed by dabbling or grazing on the surface of the water for plants and algae. Flock size varies from a few dozen to hundred or more, depending on the season and location.
