• The ermine is capable of attacking animals larger than itself, such as hares, rabbits, partridges, and grey partridges. This occurs during lean years when primary food sources are insufficient.

• Newborn ermines are born blind, toothless, with closed ear canals, covered in sparse white fur.
• The ermine hunts large rodents such as the water vole and the Siberian chipmunk, catching them in their burrows and under the snow.
• The ermine kills its prey by biting the back of the skull, like the weasel. This method is used when hunting rodents, insects, and fish.
