The stunning blue plumage of the European Roller shines at l’Empordà

“Thanks to Endesa, the Coracias project is making steady and continuous progress. The summer months are when we carry out the most important field work, with the aim of identifying their movements in order to study the habitat selection”

Initiatives for the conservation of the European Roller

The project for applying and monitoring conservation measures for the European Roller in the Parc Natural dels Aiguamolls “is making steady and continuous progress”, explained the coordinating biologist, Cristina Fernández.

The most recent nests installed at the beginning of April are controlled by a five-metre tall Wi-Fi endoscope camera that transmits real-time images and records the activity in each nest. The aim is to establish the parameters of interest regarding the birds’ reproductive phase.

Three GPS tracking devices have also been attached to three pairs of European Roller from the PNAE, which will allow us to study their movements and the selection of their habitat. This will help establish the most suitable location for future nests. The European Roller chicks are also controlled by using a ringing technique and physical data are measured.

The success of the project is measured in figures. This season eggs were laid in 26 nest boxes, 11 of which were new boxes installed this year and 16 in boxes installed in previous seasons. This success has resulted in a total of 91 successfully fledged European Roller chicks, which means an average of 3.5 chicks have survived for every clutch of eggs laid. These figures are only provisional, as there are still some eggs to be laid and these are still being monitored.

Apart from the European Roller, other species of interest that live in the PNAE and the surrounding area, such as the common kestrel and the Eurasian Scops Owl, have used the boxes this season to establish their nests and therefore, they have also benefited from this project.
