We studied the display behaviors and lek field selection of Great Bustard on the grassland of northwest in Jilin province and northeast Inner Mongolia during April to July in 2000 to 2001.We found that Great Bustard proffered to lek. Great Bustard choose their lek fields below the middle hills or at the feet of hills with smooth slope, soft soil and large landscape. We studied the fields of grassland, unburned grassland, plant numbers and average height, species richness and the density of Filifolium sibiricum, percentages and thickness of the hay. Results show that Great Bustard proffers to lek in the fields with rich plant species, higher plant, lower percentages of bare ground and lower thickness of hay.
