Abstract

The main purpose of this study is to investigate the relationship between the topography of land and vegetation and the preferred habitat of wintering cranes. Investigations were conducted twelve times in Cheorwon basin, South Korea, during two wintering seasons (12/2005 - 2/2006; 1/2007 - 2/2007). The density of rice grain in the middle of rice paddies was higher than that of the areas along the edge of rice paddies. However it was observed that red-naped cranes preferred to feed along the edges of rice paddies rather than to feed in the middle of the paddies. White-naped cranes, on the other hand, Preferred to feed in the middle of paddies. To be more specific, red-crowned cranes preferred feeding sites such as levees of the paddies or the areas where the level of the rice beds was comparatively more elevated. But the preference of the white-naped cranes turned out to be just the opposite. Another finding was that both red-naped cranes and white-naped cranes preferred concealed areas for their feeding site, and the frequency rate of their feeding in concealed areas has little to do with weather factors. This finding contradicts a widely accepted view that cranes prefer open spaces for their feeding site. Besides, red-crowned cranes, compared with white-naped cranes, preferred to feed in more concealed areas. The frequency rate of feeding in both concealed areas and non-concealed areas had little to do with the size of feeding flocks. There was no difference between a flock of fewer than five cranes and a flock of more than five cranes in terms of frequency rate of their feeding. In conclusion, the result of these investigations indicate that red-naped cranes comparatively prefer concealed areas for their feeding site, and white-naped cranes are less prone to them, and there is no direct connection between their preference of feeding site or frequency and the size of their flock. This is presumed to be the characteristics unique to their individual species.

두루미류 취식무리의 미소 취식지 선호에 대한 특성을 밝히기 위하여 철원지역에서 월동기인 2005년 12월에서 2006년 2월, 2007년 1월에서 2월까지 총 12회 실시하였다. 두루미와 재두루미가 먹이로 하는 쌀 낙곡의 밀도는 논의 중앙보다 가장자리에 많았다. 하지만, 두루미류는 논의 중앙보다는 논둑 인근 지역을 취식장소로 이용하는 경우가 많았다. 상대적으로 재두루미는 두루미에 비하여 논의 중앙 지역을 취식장소로 이용하는 비율이 높았다. 두루미의 경우 논둑이 높고 논둑 식생의 높이가 높은 경우와 논둑 높이와 식생의 높이를 합한 높이가 높은 경우를 취식위치로 선호하였다. 재두루미는 논둑, 식생, 논둑과 식생의 높이 합이 키에 비하여 높은 경우를 선호하지 않았다. 또한, 두루미와 재두루미에서 모두 은폐지역에서 취식하는 비율이 날씨요인과 관계가 없었다. 이러한 결과는 두루미류가 개방된 취식지(수평가시권이 넓은 지역)를 선호한다는 기존 가설과는 달리 은폐된 취식지를 선호하는 것으로 나타났다. 또한 종간의 비교에서는 두루미가 재두루미에 비하여 은폐된 지역을 선호하는 것으로 나타났다. 무리크기별 은폐지역과 비은폐지역 취식비율은 두루미와 재두루미 모두 무리크기를 고려하지 않은 취식비율과 차이가 없었다. 결과적으로 두루미가 은폐지역을 선호하고 재두루미가 은폐지역에 상관없이 취식지를 선택하는 경향은 취식무리의 크기에 좌우되지 않는 종 특이적인 성향을 보였다.
