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.
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 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
The habitat for the Haida ermine has been intensively reduced over the past few centuries due to old-growth timber harvest in the Tongass National Forest, an important protected area for the species, as well as industrial-scale mining on the islands, which disproportionately affects insular endemics such as M. haidarum.
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]
