February 23, 2017 – Coscoroba Swan (Coscoroba coscoroba)
Found in southern South America, these goose-like swans may be most closely related to whistling-ducks. They are the smallest species that are called swans and are around half the size of the largest swan species. Their diet is made up of aquatic vegetation, grasses, invertebrates, and fish spawn. Monogamous pairs build nests from mounds of vegetation, near water. Females incubate the eggs while males defend the nest site from predators. Both parents care for the cygnets. The name “coscoroba” comes from the sound of their call.
