The annual
bat walk and talk took place on Wednesday evening, July 8th. The weather was
fine though not as warm as in the previous week.
The talk was given
by Dr Jon Russ, a local bat expert and professional ecologist.
Three of his colleagues from the Warwickshire Bat Group, Tricia,
John and Julia, joined him to help people spot the bats on the
walk, which was fortunate because a group of 35 people gathered in
the corner of Abbey Fields car park at 9:15 pm to hear what Jon had
to say.
Jon gave a short and informative talk about bats in general
and those species to be found in Warwickshire. He also explained
some of the reasons why their numbers have declined in previous
decades, although the decline is being halted and may even be
reversing for some species, thanks to the efforts of volunteer bat
groups and the Bat Conservation Trust.

Jon and Tricia showed the
assembled people two pipistrelle bats which are currently in the
care of a local bat carer, having been found unable to fly.
Although one was feeling well enough to eat one of the mealworms
which Jon had brought along to show what is fed to bats in care.
The normal food of wild bats is flying insects - so every time we
heard a bat catch an insect, that was one less to bite us as we
walked around!
After seeing the bats in
the hand, we walked over among the trees by the old Abbey barn and
gatehouse, where a number of the Bat Group's bat detectors were
shared out, so that people could hear as well as see the bats
hunting insects over our heads. These were Britain's smallest bats:
common and soprano pipistrelles.

We then walked over to the lake in
the hope of seeing Daubenton's bats but
unfortunately there was a bit of a cool breeze and the
Daubenton's didn't seem to have come out to hunt over the water,
although we continued to hear pipistrelles there and as we walked
around by the back of the swimming pool. We also saw and heard
noctules, Britain's largest bat.

Jon had been hoping to hear the
rare Nathusius' pipistrelle by the lake, since some other members
of the bat group had heard one earlier that week, but they didn't
appear on this occasion.
