Hopefully Bob at least some of those
Swifts will be in your boxes next May :-) This is the most important time for
the non-breeders by the end of the month most will have disappeared ! just as
magically as they appeared. Good luck Bob ; quiet times here Swifts in the
village but not many around my way. My pair having a slow start still sitting
with previous clutch being kicked around the box.
