The data collection process, targeting the migration routes, and wintering sites of the rollers breeding in the Carpathian Basin has started in 2016.
So far, more than ten individuals were tagged across the project sites of Hungary and Western Romania, making sure that the main regions within the species distribution are represented by this sample. By the end of the project we will have an adequate number of individuals tagged to enable us to better understand the migration routes, the migratory behaviour and the wintering sites.
In order to be able to protect a species, we also need to protect its prey species and their habitat. As part of the dietary research on rollers, we record food remnants found within the nest boxes. These data have already provided us with a lot of information concerning the diet of rollers but they still hold some curiosities.
We’ve checked 250 artificial roller nestboxes between 30th May and 6th June, that were installed during the project in the western part of Romania. The first control targeted two main areas where the roller density is highest, whit the aim to find out the occupation rate and the stage of breeding.
We’ve installed 4 new satellite tags again this year to gain more valuable information about the migration route, and wintering sites of rollers. With the help of these data we can do more for the protection of the species. Once we know the exact location of the most important stopover- and wintering sites, we can initiate the first steps towards the legal protection of these sites by contacting the nature conservation authorities of the concerning countries.
Roller populations are radically declining throughout Europe, and the species is now extinct from many Western European countries. The population within the Carpathian Basin is relatively stable, and thus its protection is of outstanding importance for the survival of the species within the European Union.
