Introduction
The aim of this project is to track the movements of non-breeding sub-adult northern gannets from Grassholm, the worlds third largest colony, located 15km off the west coast of Wales in the Celtic Sea.
We successfully deployed 12 GPS-PTTs on sub-adult gannets that were attending club sites on Grassholm at the beginning of July.
Like other seabirds, gannets exibit delayed maturity and will not breed until they are 4 or 5 years old. Therefore, a key question in biology is to understand the movements of birds in this age class. Sub-adult birds are not constrained to any one colony and so are able to range over wide areas of ocean, potentially putting them at risk to a wide range of threats.
The information gained through satellite tracking these birds will help us to gain a better understanding of their movements, habitat requirements (which may be quite different to breeding adults), and highlight potential interactions at other colonies.
Project Partners
Researchers from University of Plymouth have attached GPS-PTT satellite transmitters in conjunction with the Royal Society for the Protection of Birds (RSPB) and Countryside Council for Wales (CCW).
