• Breeding Bird Populations in Relation to Vegetational Change in a Grassland in Hokkaido

抄録

Breeding bird populations in relation to vegetational changes by grazing were studied in a grassland in eastern Hokkaido from 1977 to 1979. During the study 39 bird species were recorded. Of them 13 species established their territories on the plot. After the grazing by cattle A. bistrigiceps and L, ochotensis were diasppeared, E. spodocephala and U. sibiricus decreased slightly, S. torquata and E. aureola did not change so much in densities, and A. arvensis increased slightly. Densities of other species remained low before and after the grazing. As a whole the total density decreased with the decrease in number of species. Open-country birds are affected through both changes in habitat and human-related activities influencing directly breeding succes.
