Abstract
The Daurian Redstart Phoenicurus auroreus has expanded its breeding distribution in recent years and now breeds in Japan, previously only part of its wintering range. We analyzed the breeding habitat selection of the population at the nest and territory scale in the Kirigamine Highlands, Nagano, Central Japan. At the nesting scale, the birds chose buildings frequently occupied by humans, while at the territory scale, they avoided sites in larger built-up areas. Our findings demonstrate that the breeding habitat selection of Daurian Redstart is influenced by environmental factors at both nest and territory scales.
We gratefully acknowledge participants in the study area for their hospitality and information on nesting sites, and especially Mr. and Mrs. Fukuzawa who provided a database of buildings. We would like to thank members of the Ichinose Laboratory at Keio University for their kind suggestions and comments. We wish to thank Dr. Takasu and two anonymous reviewers for constructive comments on a previous draft of the manuscript.
