It's Good to Put on Weight

Back at the beginning of April I came across this two year old male roosting in one of our boxes near to Antrobus and although he had managed to survive the ravages of the really cold Spring he was, unsurprisingly, decidedly underweight. Now in his third year, I found him again today roosting in the same nest box and although he had not managed to breed in 2013 he does seem to be well set for the Winter as his body weight has increased by almost 25% during the intervening period.
