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 spoonbill
This is a Palearctic species, breeding from the United Kingdom and Spain in the west through to Japan, and also in North Africa. In Europe, only the Netherlands, Spain, Austria, Hungary and Greece have sizeable populations. Most birds migrate to the tropics in winter, with European breeders mainly going to Africa, but a few remaining in mild winter areas of western Europe south to the United Kingdom. It was extirpated from the United Kingdom in the later part of the seventeenth century, although in the previous century it had been a widespread breeding species in the south-east, even near London. Sporadic breeding attempts in the early 21st century culminated with the formation of a colony at Holkham in Norfolk in 2010. In 2011, 8 breeding pairs nested, successfully fledging 14 young.
Eurasian spoonbills show a preference for extensive shallow, wetlands with muddy, clay or fine sandy beds. They may inhabit any type of marsh, river, lake, flooded area and mangrove swamp, whether fresh, brackish or saline, but especially those with islands for nesting or dense emergent vegetation (e.g. reedbeds) and scattered trees or srubs (especially willow Salix spp., oak Quercus spp. or poplar Populus spp.). Eurasian spoonbills may also frequent sheltered marine habitats during the winter such as deltas, estuaries, tidal creeks and coastal lagoons.
