Description

One hundred and eleven pellets of the Yozo Ural Owl were collected in a shelter-belt at Koshimizu district, eastern Hokkaido, during the four winter seasons from 1966 to 1977. Prey species in these pellets were identified by the teeth, bones, crania and feathers. Small mammals consisting of 7 species of rodents, 2 species of insectivores, a Russian flying squirrel, and a least weasel made a bulk of numbers in the prey species, while birds in which Pygmy Woodpecker, poultry and Brown-eared Bulbul were identified occupid relatively small part in the diet.<br>The composition of prey species, specially of rodents, showed yearly variation which seemed to be related with the abundance of prey and feeding habits of the owl. From the compotion of the rodents taken and population density of them in the wind shelter-belt, the Ural Owl seemed to prefer more Clethrionomys rufocanus than Apodemus spp. but the preference appeared to be weaker than in the red fox.
