Humans have great fun in the winter snow building snowmen, sledging and throwing snow balls. Winter for animals is not so much fun, as they must keep on searching for food. Sometimes humans provide food for animals during the winter. Garden birds are given nuts and sheep are given straw. Ploughing the soil turns up worms and grubs for seagulls to eat. Many animals find food without the help of humans so must be ready for any opportunity. Barn owls watch for mice, a robin keeps an eye on a mole hill and a squirrel searches for a nut it has stored away. Huge flocks of seabirds dig under the sand and mud for food hidden beneath the beaches.
