Eurasian eagle-owl
Even those near the northern limits of their range, where winters are harsh and likely to bear little in food, the eagle-owl does not leave its native range. There are cases from Russia of Eurasian eagle-owls moving south for the winter, as the icebound, infamously harsh climate there is too severe even for these hardy birds and their prey. Similarly, Eurasian eagle-owls living in the Tibetan highlands and Himalayas may in some cases vacate their normal territories when winter hits and move south. Even in those two examples, there is no evidence of consistent, annual migration by Eurasian eagle-owls and the birds may eke out a living on their normal territories even in the sparsest times.
Eurasian wolf
The Eurasian wolf ("Canis lupus lupus"), also known as the common wolf or Middle Russian forest wolf, is a subspecies of grey wolf native to Europe and the forest and steppe zones of the former Soviet Union. It was once widespread throughout Eurasia prior to the Middle Ages. Aside from an extensive paleontological and genetic record, Indo-European languages typically have several words for "wolf", thus attesting to the animal's abundance and cultural significance. It was held in high regard in Baltic, Celtic, Slavic, Turkic, ancient Greek, Roman, and Thracian cultures, whilst having an ambivalent reputation in early Germanic cultures.
