Stockgrove Survey June 30th

A relatively quiet night with fewer coprano pipistrelles than usual. Bob is hypothesising that they  have given burth and are foraging closer to hiome. The number of common pips was higher – maybe for the same reason, but we don’t know where they roost

The Soprano Pipistrelles were first on the scene, being heard as the three of us reached Tree 2, that was at 21.18 so not long into the survey. The Soprano Pip might have been following us on our route as it
or A N Other SP was also heard near Tree 3.

There was movement seen in Tree 7, but as no bats emerged the theory was postulated later that it was Pups in the roost, and the mother Noctules had already gone off foraging. This roost has in the past has housed male Noctules.

Bob, Gwen and Yan Yee, had taken the other side of Stockgrove, checking
the boxes, sadly none of those were occupied. They went on to Tree 7 to  spend some time there with Dick, and Sarah, who had returned to watch for emergence.

Jude had gone off on her own  making a nother
recording of her transect round the lake.

Daubentons turned up over the lake, opposite the old boathouse, which was where I stood for a few minutes.

barbastelle-wanted I  thought I’d picked up a Barbastelle on the detector II was pleased to hear from the others when they rejoined me by the lake to get ready for the Daubenton’s count, that they’d heard Barbastelles. Our first Barbs of 2014 at Stockgrove. and not at the point we usually here them

The fly through the torch beam by the Daubenton’s was 15 passes, it was still quite light over the lake at 22.13, which is when we began the count.There was a lot of Daubenton’s activity on Jude’s walkabout .

Our results vary from survey to survey but it does give us an idea of how dynamic things are at Stockgrove.
