凤头麦鸡广泛分布于黑龙江省各沼泡地区,在该省为夏候鸟,每年3月末迁至,10月中迁离繁殖地。本文通过多年的观察研究,对凤头麦鸡迁徒特点,繁殖行为,雏鸟生长发育进行了细致的观察,此外,对其食性进行了初步分析,利用计算机技术对凤头麦鸡巢在巢区中的分布特征,及密度进行了分析,得知其巢的分布形式为集群分布,其巢密度为17.2～20.5巢/公顷。
Widely distributing in the marshland region, lanpwing is a migratory bird in Heilongjiang province., migrating in at the end of March and leaving in the middle of October. Its migratory characteristics, breeding behavior and the development of nestlings were observed during 1979—1981 and 1990—1992. In addition. its food structure was analyzed. Its nesting pattern was analyzed on the computor, being of agrauping type and with a nest density of 17.2—20.5 nests per hectare.
