Mandarin Duck

Mandarin Duck

Aix galericulata
Mandarin Duck, Neil Calbrade

Introduction

The drake Mandarin Duck is gaudy and one of our most resplendent ducks. The female is contrastingly conservative, a smart grey and brown.

A timid duck of river valleys and small waterbodies with well-vegetated margins. These small ducks nest in tree cavities and will use nest boxes. Up to 12 ducklings jump from the nest before they can fly and follow the female to the nearest water.

Native of Asia, the Mandarin Duck became naturalized in the UK in the 20th century and is now found across England and parts of Scotland and Wales, with the Wetland Bird Survey reporting an upward UK trend. Outside of the breeding season, Mandarin Ducks gather in flocks relatively close to their breeding sites, although bird ringing has revealed a few long-distance movements.

Information about conservation actions

As a non-native introduced breeding species, this species does not have a conservation status in the UK. The native population in Asia is currently classified as being of least concern.

It is believed that the Mandarin Duck is unlikely to have any significant ecological impact on native species, and a risk assessment in the Netherlands classified the species as a low risk (van Kleunen & Lemaire 2015). Although this may also be the case across most of England, there are concerns that the species may impact on other hole-nesting ducks (e.g. Goldeneye and Goosander), particularly in the core Goldeneye breeding area in northern Scotland (Cosgrove 2003), and hence policy makers may need to consider whether any conservation action may be required in order to protect these native breeding species.
