We had a surprise visitor to our office this afternoon.  During the morning a pair of swallows flew in for a quick recky and flew out again, and then this afternoon this little fellow flew in but struggled to find his way out.  Its amazing to think that in a few months he will find his way to Africa and then next summer hopefully return here.  I'll make a note in my diary to see if he flies into the office again on the 19th May 2010!
