![]() Humans have also introduced invasive populations in New Zealand, which are posing a problem to native bird species. They also inhabit much of Europe, Greenland, Russia, northern China, and more. Ermines can live throughout Canada and portions of the northern United States. ![]() These mammals are incredibly widespread, and they reside across much of the northern hemisphere outside of Arctic regions. Preferred habitat also has a variety of burrows, tunnels, and crevices for the ermines to use while hunting, and establish dens. Their habitats must have high volumes of rodents and small mammals, which is why they find themselves particularly attracted to farmland. They inhabit a wide range of ecosystems, including mountains, coasts, moors, agricultural areas, woodlands, and more. They will also climb into trees to search for bird nests, including species many sizes larger than themselves.Įrmines live in colder climates throughout most of their range. The smaller females are skilled at pursuing their prey deep underground. Hunting Skill – Small and swift, ermines move quickly from burrow to crevice and between in search of food.They mark the territory boundaries by rubbing their bodies, and their anal glands, on various surfaces. The territories of males and females can overlap, and males have much larger territories than females. Territory – These creatures patrol and mark territories, defending them from other members of the same sex.Despite this, ermines put up one heck of a fight! They use their sharp teeth to defend themselves from predators. These little mammals do fall prey to other, larger predators, such as snakes, dogs, and foxes. Predator or Prey? – Of course, being so small does have its downsides.Despite the fact that rabbits are several times larger than ermines, these predators can easily overpower their prey. Food for Thought – Ermines are incredibly fond of rabbits, such as the cottontail.Learn more about ermines and their behavior below. These little predators are undeniably cute, but surprisingly fierce. Males are around a quarter larger than females, and can be several inches longer than their female counterparts. Adults are slightly longer than half a foot at their smallest, and slightly longer than a foot at their largest.
