As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Gannets Could Be Affected by Offshore Energy Developments


ScienceDaily (Nov. 8, 2012) — Scientists at the University of Liverpool have discovered that proposed offshore renewable energy developments in the English Channel have the potential to affect the foraging behaviour of northern gannets from Alderney in the Channel Islands.
The study by the University of Liverpool, the British Trust for Ornithology and Alderney Wildlife Trust, funded by the Alderney Commission for Renewable Energy, used GPS technology to track 15 northern gannets breeding on Les Etacs in North West Alderney to find out about their feeding habits and whether the routes they travelled could be affected by proposed English and French offshore energy developments.

Not dependent on specific feeding sites
The study found that on the whole gannets flew in the same direction and for the same distance but they vary significantly in the amount of time they spend searching for food which suggests that individual gannets do not depend on specific feeding sites.
Louise Soanes, from the School of Environmental Sciences, said: "We found that the area where the gannets travelled for food overlapped with nine sites earmarked for offshore marine energy developments which suggests that the feeding habits of these birds could be affected, as well as the potential for collision with wind turbine developments.
