Abstract

Abstract According to previous studies using colour rings, lesser spotted eagles Clanga pomarina have established breeding territories up to 249 km from their natal site. A colour-ringed lesser spotted eagle nestling from NE Poland settled 540 km further west in NE Germany. This male was discovered at the age of six and nested there for several years. This finding is all the more remarkable because the bird was a male, which in large eagles typically settle nearer to their natal sites than females. They apparently reproduce successfully for the first time later than females, normally at the age of five.

成熟的年龄和异常遥远的出生分散超过500公里的雄性小斑鹰
根据以往的彩色环研究,小斑点鹰Clanga pomarina在距离其出生地249公里的地方建立了繁殖地。一只从波兰东北部孵出的彩环小斑鹰在德国东北部以西540公里处定居下来。这只雄性在六岁时被发现,并在那里筑巢了几年。这一发现更加引人注目,因为这只鸟是一只雄性,在大型鹰中,雄性通常比雌性更靠近它们的出生地。显然,它们第一次成功繁殖的时间比雌性要晚,通常是在五岁时。
