摘要：
Capsule: Analysis of regurgitated pellets showed that fish were a very rare prey in the diet of the Long-eared Owl Asio otus. Remains of 38 individual fish were found at 8 of 121 nests and only in 2 out of 11 years. Occurrence tended to be more frequent in warm dry periods, when water ditches were dry.
