Nice set. I tried to get a shot like the one of the Puffin in the burrow when I went to the Farne Islands, but failed, so appreciate how difficult that was to get.
I like the first shot, but its unfortunate that there is the 3rd bird in the scene.
The gull shot is something I didn't consider when I went there either. So looking at your photos has given me a few more ideas- thanks.
