Ecology and conservation biology of birds

Ornithological research conducted at the department relates to a variety of groups and species of birds, but all are connected by issues concerning the influence of changes in the environment on the distribution and ecology of birds and interspecific relations. All of the research topics described below focus on montane and submontane populations of birds from the Western Carpathians.

The research carried out so far concerns the following issues:

- the population genetics and ecology of two sibling woodpeckers, the great spotted woodpecker and the Syrian woodpecker, in urban environments;

- the habitat preferences of two rare woodpeckers, the white-backed woodpecker and the three-toed woodpecker, in relation to the impact of forest management on the ecology of these stenotopic and indicator species;

- the influence of flood and anthropogenic alternations on breeding bird assemblages and the utility of some selected species as indicators of naturalness and biodiversity;

- the habitat and spatial segregation of two species of owls, the Ural owl and the tawny owl, in fragmented forests;

- the factors that determine the occurrence of the wood-specialist hazel grouse in fragmented forests;

- the influence of orchard management on the biodiversity of birds;

- the spatial competition of flocks of two fish-eaters, the cormorant and the goosander, during migration and wintering;

- the biodiversity of birds in the Beskid Wyspowy mountain range, the Zachodniobeskidzkie foothills, and the Raba tributary. The results and conclusions from these studies have allowed for a better understanding of the ecological and ethological factors which determine the occurrence of certain birds, especially stenotopic, rare, threatened, and indicator species. The effects of these studies have also been implemented in the practical planning of bird conservation and the monitoring of certain populations of species through the designation of protected areas and co-authorship of guidelines for monitoring and ecological research.
