While it is probable that Common kingfishers Alcedo atthis used to be found in central Tokyo, they have for long been found only in the outskirts of the city. However, recently they have appeared in many locations near the center of the city. We observed their breeding at the Akasaka Imperial Grounds in the center of Tokyo. In the first brood, four young were observed to fledge on May 20, and in the second, five young fledglings were confirmed on July 14 and 15. Some aspects of breeding behaviour of the parents are described.
