摘　　要：2011年4月20日～5月7日,以七星河自然保护区繁殖的白枕鹤为研究对象,采用扫描取样法对孵化期白枕鹤的觅食行为进行了研究。研究结果表明:白枕鹤偏好在芦苇地和苔草地中觅食,多以植物的嫩叶为食。孵化期昼间行为活动时间分配中觅食行为所占时间为39.31%。日节律显示:觅食行为在一天中出现2次高峰,即6:00～8:00和16:00～17:00之间,而在14:00～15:00出现低谷。Foraging behaviors of White - naped Crane （ Grus vipio ） during incubation were using scan sampling and focal - an- imal sampling from 20 April to 7 May 2011 at Qixinghe National Nature Reserve, Sanjiang Plain, Heilongjiang Province. Cranes preferred the leaf buds of plants in reed beds and moss grass forage. Foraging occupied 39% of daylight activities during incubation. There were two peaks of foraging, at 6：00 - 8：00 and 16：00 - 17： 00, and foraging was minimal from 14 ： 00 - 15 ： 00. Human disturbance and environmental factors were the key factors affecting foraging activity of cranes during the incubation period.
