European mouflon be divided into contact and warning calls and wailing, as well as the mating calls of the rutting ram. Just a few minutes after the birth of a lamb, the ewe utters a short, sombre, bleating noise, to which the lamb replies, also bleating. In the herd, the sheep call for their lambs using a long drawn-out bleating. Lambs who are looking for their mothers bleat loudly, almost blaring. Wailing is heard from the lambs when they are attacked by an enemy or are severely injured. No wailing sound is made by adult mouflon. When alarmed, mouflon emit a hiss
Wild horse taxonomists considered domesticated and wild horse two subspecies of the same species, the valid scientific name was "Equus caballus" Linnaeus 1758, with the subspecies labeled "E. c. caballus" (domesticated horse), "E. c. ferus" Boddaert, 1785 (tarpan) and "E. c. przewalskii" Poliakov, 1881 (Przewalski's horse). However, in 2003, the International Commission on Zoological Nomenclature decided that the scientific names of the wild species have priority over the scientific names of domesticated species, therefore mandating the use of "Equus ferus" for the horse, independent of the position of the domesticated horse. Przewalski's horse occupied the eastern Eurasian Steppes, perhaps from the Urals
