Checked the Noctule roost last night from the back garden and none were seen in over 25 minutes.
I then checked the roost this morning and could hear nothing. So, confident to say they have left with my last confirmed sightings from Sunday 8th August. They started way back on the 19th May.
Hope they come back next year. Any bets on the start date for 2011?
Also found a small Bank Vole in one of the 'hotels' yesterday afternoon.
