Bewick's Swan look-alikes

Key differences

The most common confusion species. Bewick's Swan has a smaller, more rounded yellow patch on the bill, which typically does not extend below the nostril, and a larger black tip. The Whooper Swan has a larger, more pointed yellow patch that extends to a point below the nostril, and a smaller black tip. Whooper Swans are also generally larger with a longer, more elegant neck. Their calls are more bugling and trumpet-like.

Key differences

Mute Swans are easily distinguished by their orange bill with a prominent black knob at the base (larger in males). They typically hold their neck in an 'S' curve and often hold their wings arched over their back. Mute Swans are largely silent, hence their name, only hissing when disturbed, unlike the vocal Bewick's Swan.

Key differences

The American subspecies of the Tundra Swan. While genetically very close, the Whistling Swan typically has a much smaller yellow patch on the bill, often just a small yellow spot or entirely black. Its range is North America, while Bewick's is Eurasian.
