Repatriation of Barn Owl, Little Owl and Ural Owl from the zoo Ostrava

According to the Executive Regulation No. 395/1992 Coll., the Barn Owl and the Little Owl are nowadays classified as threatened species in the Czech Republic, while the Ural owl as a critically endangered species. Landscape changes together with low food availability, increasing predation by Pine Marten, lack of nesting biotopes and nesting hollow trees, negative impact of increasing traffic, and technical traps in rural buildings, all these factors lead to a rapid decline in the owl numbers. Therefore, monitoring and reintroduction projects have been started in order to help the owl populations. This thesis focuses on recording the numbers of the Barn Owl, the Little Owl and the Ural Owl wild breeding pairs in the Czech Republic. It aims to evaluate the asset of monitoring and reintroduction to the wild populations of these species. It compiles and evaluates the numbers of chosen owl species in different localities in the Czech Republic.
