Gulls regularly line the roof of St Modwen Church in Burton. They seem to find it a good look-out for the adjacent River Trent.
Burton is of course hundreds of miles from the sea, but the Trent is navigable all the way up to the East Coast (yes, this surprised me too)... so maybe these gulls floated down from the North Sea. Hmm. Perhaps.
Incidentally, St Modwen's parish district now consists of ... basically ... the small island in the middle of the Trent river. Now that is weird.
