Rollers are secondary cavity nesters, which means, that they don't build their own nest, but using the cavities created by larger woodpecker species. As there are less and less old trees, not many natural cavities left, so the the most important conservation activity is to install artificial nest boxes.
Taking advantage of the mild and sunny weather at the beginning of February, we began to replace the timber roller nestboxes mounted on high voltage poles in Chișineu-Criș area (Arad County). These artificial nests were placed in the first year of the project and have annually a very good occupancy rate. Due to the record number of occupied nests from the last year we decided to place a larger number of wood-concrete nestboxes in this area.
Being long-term migrants, Rollers have already headed towards the southern parts of Africa. While some of them has already reached Sahel region, other individuals could have been still seen in the grasslands of Hungary in the past weeks. Number of Roller is growing year by year in the area of the national park directorate, mainly because of the nestboxes installed by professional staff. In this article we are going to detail the breeding results of Rollers in 2018.
This years’ field season has been full of hard work and closed with nice results again. Within the frame of the „Farmers for Roller” program saplings were planted in the area of Bösztör and Tass. Altogether 106 trees were planted with the active help of our volunteers. The repaired nestboxes were also re-installed in early spring to their original locations.
The bird named „Hadnagy” received its tag in the summer of 2017. The tag was working until the middle of last month, but we haven’t received any signal for the past few weeks. We started to worry that the bird died at the southern Sahara, but luckily tha tag started to send data again 2 days ago. We were exceptionally happy to see that “Hadnagy” is in Turkey already, taking the same route as he did in the autumn, instead of the usual loop migration.
