It was so good to see that I went and found a quick spot and just sat down to watch the puffins and get an idea of what they were up to. As I came along they all ducked down their burrows but gradually came out once I had settled down with more flying in from the sea. With a little knowledge gleaned from the puffin bible - The Puffin by Mike Harris and Sarah Wanless I was able to watch them go about the start of their breeding season and understand some of the postures and behaviours.
There was a bit of billing, which a puffin pair use to strengthen the bond of their partnership.
There was some gaping which looks a bit like a yawn and is a threat used by both sexes to other puffins.
A bit of wing flapping or shaking on land usually means that a puffin is getting ready to fly but doesn't want to set off on its own.
Some had dirty tummies from being down their burrows cleaning them out and maybe enlarging them ready for egg laying.
