14th December 2014
Today I went to Whitlingham with members of Norwich Bat Group to help out with the first roost count of the winter. We headed to Whitlingham Woods and into the old Lime Kiln. This was my first visit here, as earlier in the year we had been unable to unlock it. Inside we found four bats. The first one was in a crack in the ceiling and was noted as a Myotis sp, probably Daubenton's Bat. The other three, including one piggybacking on another, were Natterer's Bats. As well as the bats there were three Herald moths on the walls of the kiln. Interestingly none of the four bats were roosting in the specially made bat bricks that had been installed.
Herald moths, a species commonly found in bat hibernaculae
Moving back down Whitlingham Lane we went to look in the old railway tunnel on the edge of Trowse Meadow. There was no sign of the regular Brown Long-eared Bat, but we did find another three Natterer's Bats, two in a crack in the wall and one in a bat brick. Also in the tunnel were another four Herald Moths, one Buttoned Snout moth and also quite a lot of Cave Spiders.
Many thanks to Rich & the Norwich Bat Group for allowing me to accompany the roost checks.
