Fall in! Fall in! One post per gull, One gull per post! Line up, line up! Beaks to the North, Eyes right for the roll call! Atten——tion! All present and correct. Flock — At ease!
This poem was inspired when I noticed that the black-headed gulls that had settled to roost on the posts in the lagoon were all facing the same direction. I wonder why they do that?
