Took a trip to the Prees Branch canal to check the rafts: more minky prints, unfortunately. Hope SW will get on the case next week.
We also found several water vole latrines, some evidence of feeding - and some interesting food choices. I didn't know till I just checked now that water voles eat snails, but there were piles and piles of empty ramshorn shells, often near cut grass and vole droppings. There were also little piles of acorn shells: do water voles eat acorns too?
