| Outline of Final Research Achievements |
We investigated the seasonal changes in impaling behavior and the relationship between vegetation and prey's quantity and quality in Bull-headed Shrike. It was found out that the relationship between the impaling behavior and the annual life cycle of this species such as the time for forming the territories, the time for storing the foods before winter, the time of breeding, etc. The low community height grassland which has been maintained under the high grazing intensity had not only large amounts of impaling, but also a large number of grasshoppers.
There are advantageous conditions for the inhabiting of the shrike such as abundant in the quality and quantity of the grasshopper and easy to find the grasshopper when jumping out from the barbed-wire fence as a perch in the native grassland.
