How do you tell the difference between a Stoat and a Weasel?
If there’s one natural history question that has stood the test of time, it must be this: how do you tell the difference between a Stoat and a Weasel?
There’s an old saying that one is weasily identified, while the other is stoatally different.
It’s not the most helpful of old sayings but it does reinforce the head-scratching nature of this particular puzzle. Both species are small, brown and ferrety; they are both fairly common and widespread throughout Sussex, and they both tend to be seen in the longer grass along field edges and ditches, or darting across the footpath a few steps ahead. Stoats bound along with an arched back, whereas Weasels scurry - but both often resemble a brown blur. They do differ in size and this determines their choice of prey, with ‘wee weasels’ focusing mainly on mice, voles and small birds, while ‘sizeable stoats’ regularly hunt rabbits. The best way to tell them apart is their tail, if you manage to catch a glimpse of it. A Stoat’s will always have a black tip (pictured below), while a Weasel’s tail is shorter and never blackened.

Most people are surprised by just how small Weasels are. They’re built on the same diminutive scale as their small mammal prey, and they’re officially Britain’s smallest carnivore. Legend has it that a Weasel can slip its head through a wedding ring, so they are easily capable of nipping into a mouse-sized burrow in pursuit of a hot meal. What they lack in size, they more than make up for in attitude. Weasels are fierce and formidable predators. Their long, slinky bodies are well-adapted to winding through the twists and turns of the most labyrinthine tunnels. Day or night, there’s nowhere to hide and running isn’t much use either. Weasels are fast and agile above or below ground, and when they set their sights on a target its fate is sealed. They will even tackle a full-grown rabbit occasionally, despite it being 25 times bigger than they are, and not long ago a Weasel famously took flight on the back of a Green Woodpecker. That was one weasily identified, yet stoatally different individual.

First time in 45 Years plus I have seen a stoat near my back door, one seen a Wessel run past me in my sitting room run behind the gas fire the back out , but the Wessel spent a few minutes near my back door, the Wessels was longer than a mouse but not much bigger, any reason they are near the house.
That's great! Sometimes they come indoors, maybe because they’re curious, seeking shelter or hunting food (usually mice and other small mammals).Regards

I was flabbergasted once to see what was either a weasel or a stoat chasing a young rabbit down the road near where I lived! I live in quite a rural area. I was also surprised the other day to see video footage of a weasel dragging away a rat. What first surprised me was just how tiny the weasel was and then that the rat was not a brown rat but a black and white one like people keep as pets! Btw I was driving when I saw the one chasing the rabbit down the road straight towards me.

Thanks. On Monday we saw a little rabbit run round the footpath corner towards us. Pause the dive off into the bramble etc. Ignored us. Why? Then came a fast live bottlebrush. Long tail, black tip. Ignored us. Checked one side of the bramble, (lovely side view) then followed the scent into the other side. As you said, stoatily different from a weasel.
Where? Sorry, not Sussex, but Knightshayes in Devon. Monday 25/9/23
Thanks for the indentification advice

What a great explanation and I loved the witty final comment! Made me giggle.

I live in Eastbourne and saw a Stoat yesterday on my way home from work, I was walking along the Cuckoo Trail beside Golden Jubilee Way when it ran out from the brush and across to the other side.
Unfortunately though I was too far away to get a good look and it was too fast for me to be able to get any kind of pictures, but I knew that it 100% was not a mouse or a rat, the body was too long, even and narrow to be either.
I’ve lived in Eastbourne for over 14 years and I’ve never seen one before, it was really nice to see.

I’m excited to have spotted a weasel in Buckingham at Cornwalls Meadow just after the fun run had finished.

Today I watched a stoat rushing around in the long grass, up and down in the trees. Disappeared into a very old wood shed. Watched it for at least five minutes. In Powys.

Do you have white Stoat’s with no other markings?

Sussex Wildlife Trust:
Stoats in Sussex are usually brown with a black tip to the tail. Some stoats can turn completely or partially white in winter, but this is typically in northern parts of the UK where snow is more common. In these instances the black tip on the tail always remains.
Best article ive read all year! Comedy genius, and informative too.

About 1960 i spent some time in the Canadian Arctic at Clyde River, on Baffin Island. There were several isolated buildings with food in one. I saw an ermine (white with a black tipped tail) when getting food from this building in the winter. The building was not heated, so everything was frozen. I went to a workshop building & constructed a plywood box with a sliding door, as a live trap to catch the animal. A week later I had it.
I took it to a schoolhouse building to show the native children. The teacher released the weasel later.

I’ve seen, what I believe to be, a weasel! Not once, not twice but three times this morning. Each time it was looking at me. I’d sat near a fallen tree, hoping to photograph birds. No birds but lovely head on views of this engaging little mammal.
