Seething Wells: Prizes and Processions

This type of 'time series' data is invaluable in monitoring the diversity of species, levels of bat activity and any change along this stretch of the river. We time the boat trip to be alongside Seething Wells, as the Daubenton's bats are 'light sampling ' within their roost. Over the years we have noted changes in the local bat population, especially a reduction in the number of species. This includes the loss of serotine (now rarely recorded in the borough) and the decline in Natterer's bat registrations, only ever recorded foraging around those darker stands of riparian vegetation.

Speaking of bats, we need as many bats as possible to join the annual Seething Wells Procession on 26.2.12 (from 2.30pm, Brighton Road, Surbiton) to march under the banner of the 'Guild of Taxonomists'. Last year we had several birds, even a crocodile, but very few bats. We also need volunteers to make some batty biscuits to sustain us on our march as bats are not at their most active in February, spending most of it in torpor, although see below for some Vespertilionidae who managed to leave their bat caves last year.
