How can I follow Lucinda's bumper selection of moments from last week? Toughie, isn't it?

I've plumped for a slightly different view of a familiar bird - a black-headed gull. In winter, all that's left of the black head is two little smudges on either side of the head. Looks a bit like they're wearing earphones, doesn't it?
