Mandarin Duck vs Falcated Duck

In short

The Mandarin Duck and Falcated Duck are both strikingly colorful, but the Mandarin Duck is unmistakable with its ornate plumage and distinctive 'sail' feathers on the back. The Falcated Duck is more subtle, with a glossy green head and a falcated (curved) tertial feather. Both species are found in similar habitats, but their plumage and structure are key to telling them apart.

Identification tips

• Mandarin Duck: Look for the ornate 'sail' feathers and bright orange plumage. Males are unmistakable in breeding plumage.
• Falcated Duck: Note the glossy green head and falcated tertials. The white crescent behind the eye is a key mark.
• Both species can be found in similar habitats, so focus on plumage details.
• In non-breeding season, females and eclipse males can be more challenging to differentiate, but the Mandarin female has a distinctive white eye-ring and stripe.

Size

Plumage

Voice

Vocalizations are not the most reliable for field identification, but the Mandarin Duck is generally quieter, while the Falcated Duck may have a soft whistle.
