Nest Predation Processes and Farmland Birds: Habitat Selection and Population Dynamics of Predators and Prey"In this thesis, I investigated whether omnivorous avian generalists known to depredate nests of passerine birds, mainly the magpie (Pica pica) and the hooded crow (Corvus corone cornix), affected breeding habitat selection and population dynamics of one of their prey species, the red-backed shrike (Lanius collurio) in a Swedish farmland landscape (c. 94 km2). The studies were performed between 1997 and 2003"--Abstr. page. |
