049/365 Arctic Terns

Being a wildlife photographer, I am always striving to capture images of interaction between subjects or to get a behavioural shot of a subject. In image 049, these pair of Arctic Tern are showing both! I was ecstatic when I saw this on my computer screen. I had seen it on the LCD screen on the day and it looked good. I wanted to make sure it was sharp enough for publication before getting really excited, and I wasnt dissapointed.
