 note = {Common kestrel mainly forage voles in grasslands and farmland.Nakano city in Nagano prefecture is characterized by fruit cultivation. From the spring to summer, foraging habitat evaluation of Common kestrels was investigated by radio-tracking in Nakano City.We recorded the locations and the habitat use by transferring the information onto a 1:3000 map.In 2017 and 2018,the home-range size for one juvenile male,one adult male and one immature female was calculated using the 95% and 50% kernel method. The area of the juvenile male home-range was 12.2ha, the adult male was 1982.4ha and the immature female was 17.3ha by 95% kernel method. The area of the juvenile male home-range was 0.9ha,the adult male was 389.1ha and the immature female was 13.4ha by 50% kernel method.Kestrels actively selected rice fields than fruits garden,and preyed on voles and insects.In the spring,when the rice field was not cultivated,kestrels foraged voles by the center part of the rice field. In the summer,the grasslands sides of the rice fields managed by grass cutting were used by foraging of kestrels. We evaluated rice fields as the most important foraging habitat of Common kestrel in Nakano city., Article, 志賀自然教育研究施設研究業績 56 : 1-6(2019)},
