Abstract

: The Danube Delta is an atypical and complex ecosystem on the border of the slowly shrinking breeding distribution of Falco vespertinus . In this paper, we study the population that breeds in this area and intend to understand its relationship with the environment in these circumstances. We registered 231 breeding pairs (bp), with a local density of 0.034 bp/km 2 . We made a Nearest Neighbour Analysis which confirmed the natural condition of the facultative colonial nesting character of this species. In addition, in order to study its habitat preferences for nesting we did a binary logistic regression model and complemented its results with Manly’s standardized habitat selection index for constant resources, calculated for each habitat class. The results obtained indicate that, for nesting in the study area, this species depends (positively or negatively) on the presence of Rook colonies, the weather, the habitat diversity and fragmentation, the abundance of open

多瑙河三角洲红足猎鹰种群及其繁殖栖息地选择

多瑙河三角洲是一个非典型和复杂的生态系统，位于法尔科·维斯比提努斯(Falco vespertinus)繁殖分布缓慢缩小的边界。在本文中，我们研究了在该地区繁殖的种群，并试图了解在这些情况下其与环境的关系。共登记种群231对(bp)，种群密度为0.034 bp/ km2。我们进行了最近邻居分析，证实了该物种兼性群体筑巢特征的自然条件。此外，为了研究其筑巢的栖息地偏好，我们建立了二元逻辑回归模型，并将其结果与Manly的标准化栖息地选择指数进行了补充，该指数用于计算每个栖息地类别的恒定资源。结果表明，白嘴鸦在研究区内的筑巢与白嘴鸦种群的存在、天气、生境的多样性和破碎度、开阔度等因素有关
