I was recently lucky enough to take a trip to Grassholm - a remote island 9 miles off the Pembrokeshire coast and the third largest colony of Atlantic gannets in the world - to accompany four researchers from Plymouth and Exeter University studying the gannet colony. The name "Grassholm" is a little misleading as this welsh island appears two-thirds white. This is due to the sheer numbers of gannets, 32,000 breeding birds in fact, comprising 12% of the world's population of Atlantic gannets. An awe-inspiring spectacle as I'm sure you can imagine, but also accompanied by a potent aroma of fish and gannet dung.
The work being carried out by the researchers on Grassholm involves ringing adult gannets with GPS (Global Positioning System) loggers which will be retrieved in a years time. The data collected will then give an idea of where the gannets feed and where they travel to in the winter. I had the privilege of releasing a particularly lively ringed gannet into the air, and at 7lb in weight with a dagger-like bill this was no mean feat!
