Abstract

BACKGROUND

The Tawny owl () is a common owl species in Europe, demonstrating generalist diet strategy. Its main prey are small rodents and numerous studies show that the composition of its diet broadly reflects changes in prey species abundance in its habitats. Due to strictly sedentary habits of adult birds and their year-round territoriality, it is possible to locate habitats of their prey with a precision of several hundred metres. Analysis of owl pellets is a traditional method in faunistic studies to provide data on distribution of small mammals, especially cryptic species which are hard to be found using trapping.

NEW INFORMATION

Here, we present a dataset on mammals found in Tawny owl pellets collected during up to 13-year studies in the Kharkiv Region, Ukraine in three territories. Data from two territories were collected in a systematic way and allowed us to make analysis of seasonal, year-to-year and habitat variability in the Tawny owl diet and local mammal species composition.

摘要

背景

灰林鸮（）是欧洲常见的猫头鹰物种，展现出广食性的饮食策略。其主要猎物是小型啮齿动物，众多研究表明，其饮食构成大致反映了其栖息地猎物物种丰富度的变化。由于成年鸟类具有严格的定居习性及其全年的领地性，因此能够精确到几百米的范围内确定其猎物的栖息地。分析猫头鹰食丸是动物区系研究中的一种传统方法，用于提供有关小型哺乳动物分布的数据，尤其是那些难以通过诱捕发现的隐秘物种。
