Black-headed Gull (ringed 7Y7)

This bird has been flying back and forth between London and Copenhagen for the past fourteen years. It was originally ringed in 1993 as a first winter bird on Kensington Garden's Round Pond (where I saw it today) and obtained its second, white '7Y7' ring in Damhussoen, Copehnagen in June, 1996.

Other birds of note today were a vocal Nuthatch near the Kensington Gardens bandstand, a Redwing near Kensington Palace, Treecreeper, three Coal Tit, Goldcrest, thirteen Dunnock (my highest count here), and four Green Woodpeckers among others.
