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 least shrew
The Eurasian least shrew inhabits the northern taiga region, and is found throughout Siberia, in northern Europe (Finland, northern Sweden and parts of Norway) and on the islands of Sakhalin and Hokkaidō. It can be found in diverse habitats, including both coniferous and deciduous forests, open fields, and the edges of bogs. The population density appears to be fairly low throughout, though its prevalence may be underestimated in surveys since its small size lets it escape many commonly used traps.
