The men of Ness have set off for the annual guga hunt. The guga is the salted meat of a gannet chick. They are culled under an EU license to keep their tradition alive. A local wag has previously suggested they be boiled in diesel - guga is reportedly very oily. After a two week spell on Sula Sgeir, 40 miles north of Lewis, the men will return with 2,000 guga.
