[Foraging habitat selection of Otis tarda dybowskil during its breeding season].
From April to July of 2000 and 2001, the authors studied the foraging habitat selection of Otis tarda dybowskil in the southeast Keerqin of Inner Mongolia by sampling method. The results showed that whether at burned or at non-burned grassland, the foraging habitat of Otis tarda dybowski had the same feature in vegetation structure, the plant height was about 13 cm on average, with the highest of 30 cm, and there were abundant species of plants and insects with big density that the bird favored to eat. The bird more concerned with the abundance of plants at burned grassland, while that of insects at non-burned grassland.
