Fairy Terns mating

ANIMAL BEHAVIOUR

The male Fairy Tern must provide about four or five fish before the female accepts him as a suitable mate. He is about to take his reward in this image, but this time has held onto the fish. I spent quite a bit of time moving slowly towards the terns in order to gain their confidence and show that I was not a threat.
