Summer migrant birds - NOT amateur radio

It is fair to call me a fair weather bird watcher. I are very unlikely to look for birds in the rain! 

There have now been a couple of reports of swallows (to some they are known as barn swallows) in South Devon. The earliest I have seen them in East Anglia is April 7th. Last year there were very few.

Already returning chiffchaffs can be heard and sand martins seen in Devon.
