19.04.2023: Orsolya Kiss (Univ. of Szeged, Hungary): Conservation of the European roller (Coracias garrulus) in Hungary, HS 02.11, Institut für Biologie, Bereich für Zoologie, Universitätsplatz 2, 13.15 - 14.00 Uhr.
Birds of farmland and grasslands have declined worldwide, especially the migratory species. The European roller is a long-distance migratory species which entire European population has undergone a serious decline, and except from a few countries with current positive trends, it is still decreasing nowadays. Here we aim to present conservation of rollers in Hungary with a full annual cycle approach which is necessary to understand the processes driving these changes as migratory species use different areas during the breeding and the non-breeding season when different factors may affect the individuals. We aim to present the effect of food availability on a breeding success, the effectiveness of nest-box supplementation and predicted changes of roller distribution area in Europe as well as the movement patterns of rollers and habitat use during breeding season and also the migration phenology, migrations routes, stopover and wintering sites. Our results contribute to the better understanding of the movements and habitat requirements of the species during the full annual cycle, suggesting variability in use of migration routes and wintering areas.
