You can here the cacophony of noise when you are approaching on the boat, and it increases the minute you step off on to the island. The Arctic Terns are very protective of their young and their nests. A lot of them choose to nest on or next to the path that winds around the island. As soon as they see someone step across their imaginary boundary they leave the nest and attack. Screeching and dive bombing. A canvas hat is essential.
The Arctic Tern
To me it looks as if their feet don't grow after birth. They seem very small for the size of the bird. I'm sure there is a reason for it. Nature is good like that.
Sat on one of the many fence posts around the island. The blue rope is to stop members of the public stepping off and unwittingly onto a nest. They make nice perches.
I thought this bird was actually quite restrained, until it drew blood from my finger, while attacking my phone. If I look scared, it's because I was.
A much more civilised selfie.
The Common Tern with it's longer legs and black tip to the bill.
The Sandwich Tern. Quite different in size (larger) and has the black bill with a yellow tip and black legs.
