The action is part of a collaboration agreement signed between Red Eléctrica de España and the Department for Environmental Quality of the Government of Navarra to undertake a radio-tracking programme of Golden Eagles (Aquila chrysaëtos) in different biogeographical areas of Navarra, in order to obtain knowledge of the foraging areas, spatial use of the territory and possible impacts resulting from the installation of electricity transmission infrastructure.

The female eagle of the breeding pair from the Ribera de Navarra, which has been named ‘Haizea’ (’wind’ in Euskera), was captured with the collaboration of the MAGRAMA and forestry agents of the Government of Navarra. From the day of her capture and radio-tagging, the transmitter of ‘Haizea’ is regularly sending GPS locations, the information received will provide data about her daily movements and frequented foraging areas throughout the year.

To date, two Golden Eagles have been fitted with radio-tagging, the male (‘Illun’) of a breeding pair whose territory is in central area of the region of Navarra, and the female (‘Haizea’) of the breeding pair whose territory is in the Ribera de Navarra. Both eagles have been monitored by satellite for at least two years and the data transmitted is are already providing information on the spatial use of the territory. In the coming months, the radio-tagging of another two Golden Eagles in the region is planned, which will provide new information about their foraging areas and that will help improve the environmental management in this Autonomous Community.

From a practical standpoint, the project aims to determine the possible risks to the Golden Eagle in order to establish selection criteria when defining the location/siting of new infrastructure (electricity lines associated with the evacuation of wind farms, access routes, etc.), improve environmental management of the species in Navarra and prevent possible impacts.
