Three golden eagle chicks in the Cairngorms National Park have been successfully tagged using the latest innovative technology. Three estates in the Cairngorms National Park – including two in Strathspey – are part of this latest raptor tagging initiative, a partnership project that has been developed and funded by the Cairngorms National Park Authority and NatureScot.

The ‘Celltrack’ tags being used have come from the USA and are among the leading technology in raptor tagging. They will provide a better understanding of the species’ movements, habitat preferences and mortality.

The birds’ movements are tracked in real-time by CNPA staff and partners with transmissions coming in daily, providing a multitude of data that can help better understand the life of juvenile golden eagles, with an inbuilt alert system should mortality occur, whether through natural causes, persecution or other anthropogenic influences. The tags have the ability to detect unusual behaviour and send alerts with accurate locations.

‘Celltrack’ tags make use of an innovative dual communication system with data being sent over the mobile phone network as well as through a network of (ARGOS) satellites. By using this hybrid communication system, the large quantity of location fixes acquired each day can be transmitted over the mobile phone network, with the additional security of satellite communications when birds are out of signal.

Dr Ewan Weston, an independent research ecologist, has been in charge of tagging the golden eagle chicks under licence. He commented: “Having been involved in fitting tags to eagles for 14 years, the technological advances in the tags we use now bring data that was previously unimaginable. The data we receive, feeds into wider research on the species and covers aspects of golden eagle biology and environment, providing an insight into aspects of their lives in incredible detail. This work has included aspects of their dispersal behaviour, interaction with the landscape and developments such as wind farms.”
