The geolocators last up to two years gathering data. In summer 2019 recaptured one of the birds fitted with a with geolocator on Ortac. Finding the birds with geolocators may sound like hunting for a needle in a haystack but is not as difficult as it may sound! The geolocato-fitted Gannets have bright colour rings which are fairly easily spotted on the colony.
The 10 sponsors of our geolocators named their birds and the class of 2017 was Saoirse, John, Wilf, Hector, Prospero, Figaro, Mercury, Lysander, Quetzalcoatl and Minnie
The map for Saoirse the gannet is below, showing where she went in winter of 2017/18. You can see this gannet spent spent a lot of time around the bay of Biscay and strait of Gibraltar. We hope to return to the colony in 2020 so deploy 10 more geolocators and see if we can find any of the nine remaining geolocators.
