Swallows

On Tuesday, when I was driving to pick up some friends in the evening, I saw my first swallow of the year. I always feel happier when they arrive each year and sadder when they leave in September. I have noticed, however, that they seem to be arriving later each year and sometimes leaving earlier on their migration back to Africa. I wonder if that is a reflection on the recent summers we have been experiencing?
