2005年3~7月在新疆卡拉麦里山地区和北塔山地区的猎隼(Falco cherrug)食性研究中发现鼠类是其主要食物。调查中收集到猎隼食团342个,其中有鼠毛出现的食团是287个,占到83.9%。有鼠骨出现的食团是117个,占到34.2%。在鉴定出来的117个残留物种类中,大沙鼠出现次数超过15次。根据目击的结果分析,鼠类在食物种类中占绝对优势。由于繁殖季节对鼠类大量捕食,猛禽类能在生物防治鼠害中起到积极的作用。
From March to July 2005, rodents were found to be the main food in Falcon cherrugs feeding studies in Kalamaili Mountains and Beit Tashan of Xinjiang. A total of 342 Falcons were collected from the survey, of which 287 appeared to be mousepox, accounting for 83.9%. There are 117 food groups with rat bone appearing, accounting for 34.2%. Among the 117 residue species identified, gerbils appeared more than 15 times. According to the results of witness analysis, rodents in food categories accounted for absolute advantage. Raptor species can play a positive role in bio-control of rodent pests due to their predation on rodents during the breeding season.
