📖 1. Overview

The black swan is a large, mostly black swan that lives on lakes, rivers, and swamps rich in aquatic plants. Swans are the largest of all waterfowl.

🦴 2. Anatomy & Morphology

It has the classic swan silhouette with a long arched neck and raised eyebrow-like ridges. Its plumage is mostly black with some white wing feathers, its eyes are red or pinkish, and its red bill is crossed by a white band. Males are slightly larger than females.

🔍 3. Ecology & Behavior

An herbivore that uses its long neck to graze on underwater plants and occasionally eats insects, it is the least territorial of all swans, forming flocks and sometimes nesting in colonies. Pairs often stay together for life and wander when food is scarce.
