Rachael Maskill from the South Lancashire Bat Group was our speaker for the
evening. After a small glitch with her arrival time and initial problems
with the projector, it all turned out to be a really good evening (timewise)!
Rachael gave us lots of general information about the types of bats and their
behaviours, particularly those found in Lancashire. Most of the group had
heard of and had experience of Pipestrelles, the Long Eared Bat, Horseshoe
bat, Daubenton and the Noctule.
Fascinating information, including facts about echo location, the fact that
they are a protected species and only give birth to one baby bat a year,
their roosting habits, diet and interaction with man. Rachel had even brought
a baby bat along with her - the first time some of us had seen a real bat
up close and personal!
Once the first half of the programme was over, we had some refreshments and
then went to have a look at the slides and video clips which she had brought.
It was fascinating to see the flight path of some of the bats she had mentioned
and to know they could be identified accurately by this and also the record
of their echo location call. It was fast approaching dusk and we decided
to go outside, armed with a bat detector unit which Rachael had brought to
do some detecting and we were successful!
It was definitely something which could become addictive! One pipistrelle
seemed to enjoy putting on a show for us flying quite close to us overhead.
Rachael pointed out that because we werestanding in a crowd we gave off heat
which attracted small insects which in turn, attracted the bats who fancied
a ready made meal. It was a lovely evening to stand outside to observe and
interact with nature and we did appreciate all the preparation which Rachael
had done to provide us with a splendid interactive programme.
