Water Vole Burrow Season — Upper Thames England
The water vole — Britain's fastest-declining mammal, reduced by 95% since the 1970s through mink predation and habitat loss — has recovered in managed stretches of the upper Thames and its tributaries through intensive mink control and bank management. At peak summer density from May through September, water voles are active in daylight along bank-side vegetation, diving with a distinctive plop and chewing waterside vegetation into characteristic 45-degree-cut reeds. Sitting quietly beside a water vole stretch of the Windrush or upper Thames produces sightings of an animal that is simultaneously charming and desperately vulnerable — its round-eared, blunt-nosed, small-tailed form distinguishing it immediately from the brown rat.
About this spectacle
Standing quietly at the bank of the River Windrush near Bourton-on-the-Water on a still summer morning, you may catch the flash of russet-brown fur and hear the unmistakable 'plop' as a water vole dives from the bank into the water. These small, round-eared mammals — Britain's most rapidly declining mammal, now recovering in carefully managed stretches — are active in daylight between May and September, making patient observation genuinely rewarding. Watch for their characteristic feeding signs: reeds and grass stems cut at a clean 45-degree angle, and small latrine piles on flat stones or mud. The voles emerge from burrow entrances set just above the waterline, feeding on bankside vegetation with an unhurried nibbling motion. The Cotswold landscape of the upper Windrush provides a picturesque backdrop of water meadow and willow, and the experience is as much about stillness and attentiveness as it is about the animal itself. Sightings are not guaranteed but are genuinely likely during peak season with patience.
