摘 要: | 对长白山灰(Motacillacinerea)和白M.alba)进行了繁殖生态的比较研究,其中包括居留情况、种群密度、繁殖力、新生雏和离巢幼鸟与成鸟量度比较、雏鸟体重增长的Logistic曲线、巢位选择、育雏及食物分析,两种鸟育雏期食性以鳞翅目和鞘翅目昆虫幼虫为主,可消灭大量害虫,两种鸟和森林保护关系比较密切。

Abstract: | A study compared with the breeding ecology of Matacilla cinerea and M. alba in JilinProvince is made. It includes residence situation,population densities,reproductive capacity,ratio of mea-surement among nestlings, young birds and adult birds, logistic curves of nestings weight growth spar-row site choice,brood and food habit are analyzed.The foods taken by nestlings entirely consist of forestpests. The relationships between Motacilla and protecting forest are intimate. |
