For our bird-loving contributors and followers, an interesting story told in a brief video, thanks to The Guardian. (Click on video image to go to the source.)

Tim Birkhead, professor of zoology at the University of Sheffield, talks to Steven Morris about his study of Amos guillemots on the tiny, uninhabited island of Skomer, south-west Wales. Birkhead first visted Skomer in 1972 as a 22-year-old PhD student interested in the sex life of the guillemot. His 40-year investigation into the birds is one of the longest-running field studies of its kind.
