According to London Wiki Birds, an East Dulwich man had his earliest ever return to his Swift box yesterday by three weeks!! I know nowt about Swift breeding behaviour other than last year I had my earliest ever sightings of circa a dozen birds (my earliest) on the 21st April seen distantly from the house heading North. The East Dulwich man also has a 2nd Swift box whose occupants normally arrive between 16-17th May....their date return should be interesting?
