Daubentons on the lake
Friday, September 17th, 2010 | Author:

Last night we went on a 1.5 mile walk, organised by Herts Middlesex Bat Group, to learn more about the bats in the area using bat detectors. Our guide was bat expert Hazel Makepeace. Here is her description of the event:
Managed to have a quick whizz through my recording from last night: on the walk down to the bridge on the reserve I’ve a recording of a Noctule, then the Daubentons (at least 4) from the bridge, which we also saw. (Also at the Sopwell Nunnery site there was a Serotine, and quite a few recordings of Common pipistrelles and Soprano Pipistrelles throughout the walk).
An amazing evening, which I thoroughly enjoyed. It was a real treat to have heard and seen the daubentons on the lake. I have attached a picture of a Daubenton’s bat which I took in August of this year

The recording of a Daubenton is available as a WAV sound file here.

Batty Sounds: Daubenton’s?
Sunday, May 31st, 2009 | Author:

Our esteemed chairman Steve recorded some bat sounds a few months back. His analysis suggests that the sound in question is a Daubenton’s bat (on which, more information here). The sound he recorded is available as an MP3 file here so have a listen. Of course the sound would ordinarily be too high pitched for human ears but the special bat detector brings it within our audible range.

Howard’s report for Nov / Dec
Saturday, January 06th, 2007 | Author:

Wildlife report
There is not much noticeable at this time of year but the bats were still in evidence in November but are probably hibernating now. The Mallard population seems to be staying at the same level (between 15 -20 birds). A Sparrowhawk is sighted regularly, along with Great Spotted Woodpeckers (who are doing a great deal of damage to one of the old pollarded willow trees). Sheila has seen a Redpoll twice but no Redwings at all this year. Still, it is early days yet. There seem to be quite a lot of cats in the area which, unfortunately will take out the bank voles, etc, but they may also help keep down the rat population, so they are a mixed blessing!

Flora
A single Marsh Marigold flowered on Xmas Eve (or was first noticed then!). This must be a record. Some of the trees are in bud – it seems as if they have only just lost their leaves.
