Late late swallows - NOT amateur radio

A surprise today was seeing 2 late (for this part of the world) swallows at Little Walsingham. I was not expecting these at all. I am pretty sure this is the latest I have ever seen these in East Anglia (Oct 2nd). They were probably a late brood and no doubt our settled warm weather is leading to some confusion! A few sharp frosts will soon trigger them to get a move on and head south on their long migration.
