黑眉苇莺繁殖期领域性行为的研究

On Territorial Behaviour of Black-browed Reed Warbler in Breeding Period

１９８７年５～７月在吉林省敦化市黄泥河林业局都陵林场，对黑眉苇莺繁殖期（孵卵与育雏期）的领域性行为进行了观察。该鸟严格地在沼泽草甸灌丛中选择领域，其领域以取食、繁殖为目的。它的领域面积的大小，受食物丰富度、种群密度、邻接巢对之间的行为和其他因素的相互作用等影响。领域的大小在孵卵期和育雏期是稳定的。黑眉苇莺在领域内主要在０～１ｍ植物高度间取食；对同种的入侵攻击行为强烈，而对异种则基本无反应。

It carried out observation for the territorial behaviour of Black-browed Reed Warbler in breeding period (incubation and feeding nestling),from May to July,1987 at Duling Forestry Centre, Huangnihe Forestry Bureau, Dunhua City, Jilin Province.The birds select their territory strictly in grassy marshland or shrub for their breeding and foraging. Factors influenced the territorial size include food abundance,population density,action on each other between behaviour and psycology in the neighbourhood birds,etc.. The size of territory doesn't vary in the period of incubation and feeding nestling.Foraging hight of the birds is at 0～1m mainly. The birds attack same species that intrude into their territory,and they don't react for other species on that does.
