摘要

遥测研究已经为濒危猛禽提供了充足的信息，但对常见物种的空间利用和分布知之甚少。在这里，我描述了2014 - 2016年在爱沙尼亚东南部研究的一只gps追踪的成年雄性秃鹰的家庭范围和繁殖分布。这只秃鹰的家园范围覆盖8.3平方公里(内核估计95%)，核心范围为2.1平方公里(内核50%)。栖息地在繁殖季节增加，但在迁徙前又减少。令人惊讶的是，在连续的两个繁殖期，它们的巢穴位于栖息地的相反边缘，彼此相距1.7公里。

Home range size and breeding dispersal of a common buzzard (Buteo buteo)

Abstract Telemetric studies have provided ample information on threatened raptors, but still little is known about space use and dispersal of common species. Here I describe the home range and breeding dispersal of a GPS-tracked adult male common buzzard, studied in south-eastern Estonia in 2014–16. This buzzard’s home range covered 8.3 km2 (kernel 95% estimate) with the core range being 2.1 km2 (kernel 50%). The home range increased in the course of the breeding season but decreased again before migration. Surprisingly, the nests in the two successive breeding years were located in the opposite margins of the home range, 1.7 km from each other.
