I hope this reaches Garth,
thank you for your report on the Worcester swallows.it’s fascinating.
After an early arrival, then a slow start to lay, we in S.W.Wales have had a good year.not as good as last year with some brooding 3 times. but better than predicted .
Obviously ,I have no ringing data but our average was 4 chicks. The latest batch was rather late fledging late Aug.
Is there anywhere I can get more info about your work ?
“best wishes swallow lady”
