We observed the behavior of eleven female Mandarin Ducks Aix galericulata during the incubation period. They left nests twice a day, in the early morning and evening. After that, they bathed, preened and foraged hurriedly in a short space of time. They were absent from the nest for a shorter time on the day before fledging and on the morning of fledging day than on other days during the incubation period.
