Abstract
European rollers (Coracias garrulus) were almost extinct from large parts of Hungary in the 1970–1980s.However up till now their population size increased considerably, mainly due to a nature conserva-tion campaign, supplying artificial nest-boxes for breeding. We studied which factors affected rollers’occurrences at the landscape scale in southern Hungary, under natural circumstances and when artificialnest-boxes were supplied. We analyzed the composition and the configuration of the landscape at twospatial scales. We found that beside the presence of natural grasslands, heterogeneous landscape pro-vided high quality breeding and hunting sites favorable for rollers. Even though habitat characteristicsof roller territories with natural holes or nest-boxes were similar, breeding sites without artificial nest-boxes harbored higher coverage of forests and heterogeneous agricultural areas. Sites with occupied andunoccupied nest-boxes considerably overlapped, suggesting that the available habitats were not satu-rated. Nest-box supplementation proved to be an effective tool for rollers’ conservation in areas wherenatural nesting sites were limited, but prey resources were available. Consequently, the preservation oflandscape heterogeneity is a key factor which should be taken into consideration in the conservationmanagement of roller populations.
