The Stoat is slightly larger. It has a longer tail with a black tip.
The separation between the brown colour and the white colour is less sharp and more wavy on the Least Weasel.
The Least Weasel's fur does not turn to white in winter.
There can be two litters of 4 to 9 young per year.
The Least weasel cannot stay very long without feeding. Populations are dependent of the abundance of preys.

Least Weasel (Mustela nivalis)
We were two photographers during this photo session around the ponds.
After having seen this Least Weasel, we have positioned ourselves to prevent it to quickly escape and to shoot a few pictures. Then we have walked away not to disturb it during a too long time and letting it going on hunting for its survival.
