Usually by this time I have seen quite a few swallows here in East Anglia, UK. They migrate from deep in Africa (often South Africa) and I usually see them here in East Anglia, UK from April 7th. In South Devon they are usually arriving by the beginning of April. Sand Martins arrive sooner. I remember my dad telling me when he first saw them. He died in 1987 and many is the time since when I have missed talking with him.
I know there are swallows around in Devon - they appear every day in the reports - but I am surprised not to have seen
any up here yet. I
may have seen one last week at Felixstowe Ferry but I was not certain. I
definitely saw a house martin.
So, I am beginning to wonder if there are
fewer swallows about this year, as by now I would be seeing them quite commonly on telegraph wires. Of course, it could just be that I have been unlucky. It is not as if I have not been looking.
