Abstract

Migration and over-wintering strategy of raptors can be influenced by many factors such as sex, age and experience of birds, habitat variability and food availability. Based on the telemetry data of nine Red Kites (Milvus milvus), we observed in situ their wintering grounds in southern Italy during winter 2019/2020. Red Kites originated from Austria and the Czech Republic arrived to their wintering grounds from 10th September to 5th December 2019 and departed between 9th February and 7th May 2020. Tagged Kites stayed in their wintering grounds from 73 to 207 days (mean 135±46 SD). These birds occupied home range and the core area from 39 to 9,351 km2 (KDE 95%; mean 3,591±3,460 SD) and 6 to 1,998 km2 (KDE 50%; mean 566±483 SD), respectively. We observed a total of 242 Red Kites at nine communal roost sites (min. = 14, max. = 45 individuals) used by tagged Red Kites. Roosts were situated at an average altitude of 630 m above sea level. Agricultural countryside with small or large fields, small or large forest patches, meadows, pastures, sheep or cattle farms surrounded areas around communal roosts of Red Kites.

对在意大利越冬的中欧红鸢行为的观察

猛禽的迁徙和越冬策略受到许多因素的影响，如鸟类的性别、年龄和经验、栖息地的变化和食物的可用性。基于9只红鸢(Milvus Milvus)的遥测数据，我们在2019/2020冬季在意大利南部实地观察了它们的越冬地。红鸢来自奥地利和捷克共和国，于2019年9月10日至12月5日抵达越冬地，于2020年2月9日至5月7日离开。被标记的鸢在越冬地停留73 ~ 207天(平均135±46 SD)。这些鸟类占据了39 ~ 9351 km2的栖息地和核心区域(KDE为95%;平均3,591±3,460 SD)和6 ~ 1,998 km2 (KDE 50%;平均566±483 SD)。在9个公共栖地共观察到242只红鸢(最少14只，最多14只)。= 45只)，被贴上标签的红鸢使用。栖息在平均海拔630米的地方。有或大或小的田地、或大或小的森林、草地、牧场、牧羊场或养牛场的农村地区围绕着红鸢的公共栖息地。
