Seven turned out to check what bats were using the Key’s Beck pond site where the spring bat box check showed a complete absence of bats. We managed to do recording at four different points around the site which consists of two ponds with a causeway between the two. Recorders were stationed at the northern and southernmost points of the pond, on the causeway and also on a forest ride through some mature trees to the west of the ponds. We started at 8.50pm and finished at 10.30pm. We were a little surprised to find access tricky due to the extensive harvesting that is going on in the area but managed to all get down to the site ready to start on time. The felling will clearly make the site more exposed in the short term but will recover after restocking.
Results are quite interesting. Common pips were very active around the causeway between the two ponds.with an average of a pass every 20secs or so throughout the survey period, whilst none of the other points recorded anywhere near that activity. The lower pond where I was was a very sheltered spot, and plenty of midges, but very little activity which was a surprise. The upper pond site and the ride site had good Common pip activity but only in short bursts which is again surprising when compared to the causeway site. Despite the large area of water only a single Myotis species, almost certainly a Daubenton’s from the sonogram, appeared to do a fly through the site without stopping being recorded at the upper pond, on the causeway and at the lower pond all in the same 5 min period but not at any other time. Colin, on the ride, picked up a Brown long-eared bat at 22.18 and 22.19 and this was the only other species recorded. It ties up with the lack of usage we have found at the bat boxes but we will see what the autumn check turns up there.
