During summer after the hatching of eggs and the quick growth of ducklings the mandarin, like all other ducks, moults its feathers. This period is also known as "eclipse". It is most noticeable in the brightly coloured males that become predominantly brown though they can still be distinguished from the females by their distinctive beaks.

As autumn approaches a new set of feathers grows and quite quickly the males assume their multi-coloured best. On a recent visit to Cannop Ponds in the Forest of Dean we saw the mandarins by the waters edge, under the overhanging trees. Many birds were perched on the low branches of alders. The second photograph shows a bird standing on a section of submerged branch, its lower body reflected in the water, with real and reflected branches in the background
