What do House Sparrow eat?

What do House Sparrow eatAs an adult, the House Sparrow mostly feeds on the seeds of cereals and weeds, but it is opportunistic and adaptable, and eats whatever foods are available. It can perform complex and unusual tasks to obtain food, such as opening automatic doors to enter supermarkets, clinging to hotel walls to watch vacationers on their balconies, and nectar robbing kowhai flowers. In common with many other birds, the House Sparrow requires grit to digest the hard seeds in its diet. Grit can be either stone, often grains of masonry, or the shells of eggs or snails; oblong and rough grains are preferred.

Animals are another important part of the House Sparrow's diet, chiefly insects, of which beetles, caterpillars, dipteran flies, and aphids are especially important. Various non-insect arthropods are eaten, as are molluscs and crustaceans where available, earthworms, and even vertebrates such as lizards and frogs. Nestling House Sparrows are fed mostly on insects until about fifteen days after hatching. They are also given small quantities of seeds, spiders, and grit. In most places, grasshoppers and crickets are most the abundant foods of nestlings. True bugs, ants, sawflies, and beetles are also important, but House Sparrows will take advantage of whatever food is most abundant to feed their nestlings.
