Arctic Terns at the Isle of May reserve just off the coast of Anstruther in Fife, Scotland.
The boat slipway is surrounded by the Terns nesting grounds, and on this visit the chicks had just hatched, so the usually benign terns were very aggressive.
We were warned to wear a hat and carry a tripod or similar over our heads so that they attack that rather than us, as they could draw blood.
However they also poo on you, I took an allergic reaction and had eyes like golf balls on sticks for a while after.
Thankfully Anstruther boasts the best fish and chips shop in the UK, so a wee smoked kipper supper helped to soothe the pain.
Great place to get all up close with puffins, if thats your thing.
