Spatial and numerical responses of Red Kites Milvus milvus to the Common Vole Microtus arvalis population outbreak

Popis výsledku v původním jazyce

Predator behaviour can be determined by many factors such as prey availability, individual and habitat characteristics, and intraspecific or interspecific factors. Using satellite telemetry, we document the pattern of spatial responses of the Red Kites (Milvus milvus) to increasing availability of its dominant prey, the Common Vole (Microtus arvalis), from 2018 to the beginning of 2020 in the Břeclav District, Czech Republic. We found a relationship between the population density of Common Voles and home range size of Red Kites. Home range sizes decreased between the winters of 2018 and 2019 when prey density increased to a medium level. Based on the data of three censuses (January 2018, 2019 and 2020) focused on wintering Red Kites at communal roosts in the same region, we analysed the numerical response of these raptors to vole density. Wintering numbers of Red Kites did not respond to increasing prey density until it increased to the highest level in winter 2020. These results suggest that spatial and numerical responses of Red Kites differ in sensitivity to increases in vole density and are therefore triggered at different periods of the vole population cycle.
