Arctic terns are in my opinion one of the most beautiful birds in the world. The problem I have with them is that when they lay eggs and produce chicks, they become the most protective of all parents. This translates into them pecking the head of every visitor to the Farne Islands! this year 2013 is the worst they have ever been, for reasons I am unsure about. A 3 hour visit to Inner Farne was accompanied by around 100 pecks!
