Abstract
Although the Daurian Redstart Phoenicurus auroreus is currently classified as a winter
visitor in Japan, we collected 13 nests of this species in Mt. Yatsugatake, central Japan. They were
all bowl-shaped with a base extending to one side. The confirmed breeding nests had an outer
diameter of an average of 129mm, an inside diameter of an average of 73mm and a depth of an
average of 31mm. They were composed primarily of fine roots, bryophyta and grass stems with
animal hair, feathers and grass leaves built into them. Many of the nests had a nest cup lined with
animal hair on fine roots. The basal part of many nests was also built mainly of bryophyta, fine
roots, grass stems, twigs and tree leaves.
