Bats in woodshed

   My observations on the Bats in the loft over
the wood shed at the Farm this season were as follows: -
May 1. First date of inspection. No Bats in shed.
May 2  Second date of inspection. No Bats in shed
May 3  Third  date of inspection. No Bats in shed
May 4 A single Bat clinging to the roof in the usual
place. It was a large brown one, however, evidently belonging
to a species different from the kind we usually have in summer
in this shed.
May 5. Two Bats of the usual summer kind in the usual place.
May 6 - Four Bats of the usual summer kind in the usual place
May 7-17 No observations
May 18 - Sixteen Bats of the usual summer kind in the usual place.
May 19-20 No observations
May 21. Eighteen Bats of the usual kind in the usual place
  For a month or more after this the number ranged from two Bats
to eighteen. I saw no young this year.
