This photo was taken on the Isle of May, near Anstruther during June 2008. Technically it isn't a great photo, but how often do you get a photo of two puffins flying into each other? The light was behind the puffins so it took quite a lot of work to get any detail to show.
The technical information is as follows.
Camera - Canon EOS 30D
Shutter speed - 1/8000
