where do sparrows migrate to in the winter
House sparrow Most house sparrows do not move more than a few kilometres during their lifetimes. However, limited migration occurs in all regions. Some young birds disperse long distances, especially on coasts, and mountain birds move to lower elevations in winter.[102][125][126] Two subspecies, P. d. bactrianus and P. d. parkini, are predominantly migratory. Unlike the birds in sedentary populations that migrate, birds of migratory subspecies prepare for migration by putting on weight.[102]
Snowy owl The snowy owl is typically found in the northern circumpolar region, where it makes its summer home north of latitude 60Â° north. However, it is a particularly nomadic bird, and because population fluctuations in its prey species can force it to relocate, it has been known to breed at more southerly latitudes. During the last glacial period, there was a Central European subspecies, Bubo scandiacus gallicus, but no modern subspecies are recognized.
