Canals and waterwayswhilst we were eating our evening meal, we were treated to a wonderful flying display by a whole squadron of bats immediately outside our window.
Graham Very likely there is a Daubenton's roost near your mooring, perhaps in a crack in a bridge. These are the small bats which fly at about a foot over the water. They normally come out about half an hour after sunset and circle round for a bit before setting off to forage (the circling may allow bats which had poor foraging the night before to follow those which set off confiently towards a good area). Pipstrelles usually forage over the towpath rather than the water and do dizzying aerobatics at head height or above. I recently saw a Serotine above the Avon at Charlecote - a much larger bat, foraging at about 20' along the line of riverside trees. Sean
