Problems of hybrids and non-native species of falconry birds of prey (Falconiformes)
 RICHTROVÁ, Zuzana
There have been more and more discussions of the influence of falconry on wild populations of birds of prey in recent years. Where the main topic previously dealt with stealing young birds from nests, today's concerns revolve around interspecific hybrids and non-native species. This thesis therefore focuses on these issues and attempts at collecting available information. The main finding is that only few serious researches have been carried out on this topic so nobody can make a conclusion that would subsequently lead to practical interventions. The available sources clearly show that non-native species are most likely not to pose any risk to nature. In contrast, the information on hybrids was very inconsistent and often diverged. It is probable that hybrids have some influence in nature; but to determine its severity and whether or not intervention is required, we need to carry out a detailed scientific study. IAF (International Association for Falconry) recommends a number of measures that seem to be sufficient at the time and they include: - ban on arbitrary discharge of hybrids and non-native species into the wild - ban on free-hacking while training these birds - requirement to use telemetry in training - requirement to use maximum effort in order to trace these birds in case they get lost - imprinting of young hybrids in species that is not found in nature in the given area Improvement should mainly be made in the registration of birds of prey. At this point and in most countries, it does not allow you to trace the birds' parents reliably and, as a consequence, one cannot unambiguously determine whether the bird in question is a hybrid or pure species.
