Abstract

Abstract We studied various aspects regarding migration behavior of the Common Buzzard for two subspecies (B. b. buteo and B. b. vulpinus) transiting the region which overlaps with the Western Black Sea Corridor. Using vantage points set across Dobruja we managed to count 2,662 individuals. We highlighted the seasonal and diurnal peak passage, flight directions and height of flight for each season. Our results suggest that 57% of the counted individuals belongs to long-distance migrant Steppe Buzzard - B. b. vulpinus. The peek passage period in autumn migration was reached between the 26th of September to the 6th of October, while for the spring migration peek passage remained uncertain. The main autumn passage direction was from N to S, and NNW to SSE but also from NE to SW. For spring passage the main direction was from S to N but also from ESE to WNW. Flight height during autumn migration was mostly at high altitude while in spring migration was more evenly distributed. The most significant activity was recorded in the second time period, between 10:01 and 13:00 (43%).

杜鲁加地区秃鹰(Buteo Buteo Linnaeus, 1758)的迁徙策略

摘要本文从多个方面研究了在黑海西部走廊重叠地区迁徙的秃鹰两个亚种(buteo和vulpinus)的迁徙行为。利用在Dobruja的有利位置，我们统计了2662人。我们突出显示了每个季节的季节性和日间高峰通道，飞行方向和飞行高度。结果表明，57%的被计数个体属于长途迁徙的草原秃鹰。秋季迁徙高峰期为9月26日至10月6日，春季迁徙高峰期为9月26日至10月6日。秋季主要通道方向为北北向南、北西北向南、北东向南、北东向南。春季通道以南北向为主，也有东南向西北偏西方向。秋季迁徙的飞行高度以高海拔为主，春季迁徙的飞行高度分布较为均匀。最显著的活动记录在第二个时间段，在10:01和13:00之间(43%)。

期刊介绍： Travaux du Muséum National d’Histoire Naturelle "Grigore Antipa" (The Journal of "Grigore Antipa" National Museum of Natural History) is an international, open access, peer-reviewed journal devoted to zoological research that is published biannually by the "Grigore Antipa" National Museum of Natural History from Bucharest (Romania). It publishes original research or review articles dealing with all aspects of general zoology (taxonomy, systematics, evolutionism, faunistics, zoogeography, palaeozoology, animal ecology, invasive species of animals, parasitism, biodiversity conservation). Also, some book reviews, anniversaries and obituaries of some personalities of science world can be accepted to be published in this journal. In the present, the only language accepted for this journal is English. The scope of the journal is to publish, disseminate and provide open access to the results of the original studies made in different zoological fields, in Romania and worldwide. Every submitted manuscript is subject to peer-review, being reviewed by at least two peers qualified to evaluate it. Distinguished authorities form the international advisory board which guarantees the high scientific profile of the journal.
