📖 1. Overview
The Canada goose is a large North American goose marked by a long black head and neck and a white patch near the chin. It adapts so well that it has settled in cities and suburbs with well-kept lawns.
🦴 2. Anatomy & Morphology
It has a long black head and neck with a white mark near the chin, a brownish-grey back, and a cream to white belly and rump. Males are slightly larger than females, though both look similar, and goslings have yellow down with grey-green feathers on the back.
🔍 3. Ecology & Behavior
It is herbivorous, eating leaves, grasses, seeds, berries, algae, and roots, and uses comb-like ridges along the edge of its bill to pull grass. In flight, flocks fly in a V-formation and take turns leading, covering up to 2,400 km in a single day. Pairs stay together for life, and parents with goslings gather into group flocks.
