About the European Water Vole
The European water vole (Arvicola amphibius) or northern water vole is a semi-aquatic rodent. It is often informally called the water rat, though it only superficially resembles a true rat. Water voles have rounder noses than rats, deep brown fur, chubby faces, and short fuzzy ears; unlike rats, their tails, paws, and ears are covered with hair.
In the wild, on average, water voles only live about five months. Maximum longevity in captivity is two and a half years. Water voles reach 14–22 centimetres (5.5–8.7 in) in length, plus a tail which is about half the length of the body. Weights reported for adults are variable. It is possible for large, optimal adults to weigh as much as 225 to 386 g (7.9 to 13.6 oz). However, these are peak weights. Elsewhere, the mean body mass has been reported as 60 to 140 g (2.1 to 4.9 oz), although this figure includes immature water voles. The minimum weight to successfully breed as well as to survive winter is reportedly 112 g (4.0 oz) in females and 115 g (4.1 oz) in males. As a species, the mean body mass is claimed as 140 g (4.9 oz).
Overall, European water voles are a uniform dark brown colour, with slightly paler coloration on... Wikipedia →

GBIF citizen-science records
It is estimated from how often the European Water Vole is recorded against all the mammals logged in London (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
