520 3# ‡aExplains how resident and migratory winter birds cope with dark and cold. Gulf Stream tempers cold, and anyway such birds can manage cold, but cannot lay up fat because of need to fly. Herons manage along seawater's edge when fresh water is iced up. Some insect eaters switch to plants in winter, but goldcrest takes risk of finding insects, and many die in bad season. Terns cannot manage when prey goes deeper, so all migrate. Diving ducks have no problems other than dark. Purple sandpiper manages well at tidemark on snails. Hoodie crows and gulls are opportunists, closely linked to human rubbish. Some berry eaters migrate south as late as Feb. in good years.
