We summarize records of courtship and offspring feeding for 16 resident passerine birds based on long-term observations made by amateur ornithologists in Kanagawa Prefecture, Japan. Courtship feeding was detected in nine passerine species, including two that had not been previously reported to perform this behavior in Japan. Fledgling feeding and food transport to nests were detected in almost all of the species. Courtship feeding was detected mainly in early spring, but in some species it also occurred in winter. We discuss briefly the implications of the results, as well as possible biases and limitations of citizen-based research.
