DNA Results in

The 20 DNA samples we sent for testing from the 20 most difficult to identify individual whiskered and Brandt's bats out in the field have been returned and of the 20 in-field identifications we made, 3 were incorrect.
We are now writing up the results from this year's surveys to add as an appendix to the 2015 report (available here)

Hanging Harps

On Saturday 17th September we upped the number of traps from the usual 2 to 7 plus a couple of mist nets. This worked well with every trap catching bats despite the bright harvest moon breaking through the clouds.
Two traps were suspended in front of the cave entrance as we have observed many bats entering the cave higher up.
A total of 34 bats of 5 species were caught.

Trapping on the bank holiday weekend

On Saturday 4 of us undertook a survey at Good Luck mine. A damp night with rain at the start meant it was a bit touch and go whether swarming would take place that night. A slow start to the evening but in the end 14 bats of 3 species were caught.

Success at Jug Holes

It's always nice when you catch enough bats to turn the page over to the other side and we caught 27 bats on Friday night.
These consisted of:
4 Brandt's
14 Daubenton's
3 Natterer's
5 Whiskered
1 WAB

Best Trapping Night

On 23rd August we had our best trapping night of the project so far. A total of 60 bats were caught which consted of:
17 Brandt's
6 Brown long-eared
13 Daubenton's
7 Natterer's
8 Whiskered
1 WAB
8 recaptured bats
This was the first time Natterer's bats have turned on on a survey this year, a whole week earlier than last year.

2016 Trapping is underway

We've undertaken 4 surveys so far this year and have caught 45 bats (one night was a washout with no bats caught). Keep your eye on this page for more updates as we go along!
