The stoat is similar to the least weasel in general proportions, manner of posture, and movement, though the tail is relatively longer, always exceeding a third of the body length, [clarification needed] [24] though it is shorter than that of the long-tailed weasel. The stoat has an elongated neck, the head being set exceptionally far in front ...
The American ermine has a body plan typical of weasels. It has short legs, a long body and neck, and a small triangular head with short round ears. It has a brown dorsum with a white venter (except during winter when the coat is fully white) and a short, black-tipped tail.
The stoat (Mustela erminea) and long-tailed weasel (M. frenata) steal ducks' eggs. Snakes of the genera Dasypeltis and Elachistodon specialize in eating eggs. Brood parasitism occurs in birds when one species lays its eggs in the nest of another. In some cases, the host's eggs are removed or eaten by the female, or expelled by her chick.
Skulls of a long-tailed weasel (top), a stoat (bottom left) and least weasel (bottom right), as illustrated in Merriam's Synopsis of the Weasels of North America. The long-tailed weasel is the product of a process begun 5–7 million years ago, when northern forests were replaced by open grassland, thus prompting an explosive evolution of small, burrowing rodents.

The short-tailed weasel is the common name in North America for two species once considered a single species: Stoat or Beringian ermine (Mustela erminea), native to Eurasia and the northern portions of North America; American ermine (Mustela richardsonii), found in most of North America aside from the northern areas
Eggs of: ostrich, emu, kiwi and chicken. Egg size tends to be proportional to the size of the adult bird, [citation needed] from the half gram egg of the bee hummingbird to the 1.5 kg egg of the ostrich. Kiwis have disproportionately large eggs, up to 20% of the female's body weight. [18]
Unlike the stoat, which often engages in surplus killing, the mink usually limits itself to killing and eating one fowl during each attack. Studies in Britain indicate poultry and game birds only constitute 1% of the animals' overall diets; [ 29 ] small mammals, especially rabbits, tend to dominate, followed by fish and birds, especially ...
