The UK has six species of deer living wild.

Red Deer, Cervus elaphus – true native species found in Scotland, the Lake District, and on Exmoor, as well as Northern Ireland, much larger than all other deer, and indeed any other British mammal. Distinctive rusty, red-brown colour in summer. Short tail and pale rump patch.

Roe Deer, Capreolus capreolus – true native species present across the whole of England, Scotland, and Wales. Rusty red coat in summer, grey-ish in winter. Prominent white rump and no tail. Females have a small
tush or tuft of hair on their rump in winter.

Fallow, Dama dama – native and living freely across England and Wales and into Scotland as well as Northern Ireland, but also. Their coat is quite varied some pale, some less so but with white spots. Usually have a distinctive black inverted horseshoe shape on their rump, and a black stripe on their tail. Only species in the UK where the stags have palmate (hand-shaped) antlers.

(Reeves’) Muntjac, Muntiacus reevesi – introduced species, also known as the Barking Deer for its canine-sounding call. Smallest of deer in UK. Russet brown, distinctive shape and hunched posture. Wide, flat tail with an often-displayed white underside. Present across all of southern England.

Chinese Water, Hydropotes inermis – introduced species. 10 percent of world population found in East Anglia and a few other places in England. Usually russet brown coat, which turns grey in winter. Distinctive tusks in males rather than antlers. Often described as having a Teddy bear face with round and protuberant forward-facing ears. Short tail, rump has no distinctive markings, making it distinct.

Sika, Cervus nippon – introduced species originally on Brownsea Island but present in that region and North West Scotland, also Northern Ireland. Similar coats to Fallow Deer but shorter tail and a less distinct black stripe, distinctive white rump, also noticeable white glands on the hind legs of the deer.

TL:DR – We saw an otter preening on the banks of a local waterway in early Spring 2022.

A road that crosses the River Great Ouse a short way north of our village has the fabulous name of Twentypence Road. Downstream of the river is the Twentypence Marina where often you might espy Kingfishers darting about from branch to reed. Indeed, we parked up ahead of a country walk there and saw two within a couple of minutes of getting out of the car.

Upstream of the bridge is a nice walk that can take you along the edge of farmland to walk on the flood bank or you can head back towards our village along the Cottenham Lode. There is also a fishing lake surrounded by trees, which is often good for various bird species and beyond is a growing herd of roe deer to be stalked. However, today we took the north bank of the river and headed for the footpath beyond the riverside cottage.

It was in front of the cottage that I spotted a creature cleaning itself on the riverbank. An otter, or more precisely Lutra lutra, the repeated word, a tautonym, implying this species is the “archetype” of the Lutra genus. The species is often called the European or Eurasian Otter and sometimes that is qualified as River Otter to separate it from the Sea Otter. Anyway, it was a surprise to see it out in the open rather than simply catching a glimpse at a distance of a head ducking under the water. It made my day, as one might say.

Incidentally, otters are fairly closely related to weasels and stoats but also to seals, seals are certainly closer genetically speaking to otters than they are to dogs with which they are often compared.

The Chinese Water Deer (Hydropotes inermis inermis) is not a species native to the UK as its name might suggest. It’s an Asian species related to the Korean Water Deer (Hydropotes inermis argyropus). There are numerous CWDs in England that are descended from escapees from Whispnade Zoo in the 1920s.

I saw a couple of them on the recently opened new section of RSPB Ouse Fen this morning. Coincidentally, the deer was mentioned on the BBC’s One Show on 31st January. The genus name Hydropotes derives from the Greek meaning “water drinker”. The inermis component of the scientific name comes from the Latin meaning unarmed, alluding to the animal’s lack of antlers. It is worth noting that both male and female adults have protruberant upper canines, which look rather menacing despite the animals rather “Teddy Bear” facial features leading to it being referred to as as a Vampire Deer in some camps. The canines in the two females I espied today were not particularly prominent.
