Indian House Sparrow
Widespread and abundant in cities, neighborhoods and farms. Avoids dense woods. Flocks cluster in dense bushes, bustling around and chattering to one another. Males have smart black bibs, bright rufous napes, and stunningly patterned wings with brilliant buffs and browns. Underparts are pale pearly-gray. Females are plain brown with cute face and lighter eyebrow. Native to Eurasia; introduced to much of the rest of the world.
Habitat
House Sparrows are closely associated with people and their buildings. Look for them in cities, towns, suburbs, and farms (particularly around livestock). You won’t find them in extensive woodlands, forests, or grasslands. In extreme environments such as deserts or the far north, House Sparrows survive only in the immediate vicinity of people.
Food
House Sparrows eat mostly grains and seeds, as well as livestock feed and, in cities, discarded food. Among the crops they eat are corn, oats, wheat, and sorghum. Wild foods include ragweed, crabgrass and other grasses, and buckwheat. House Sparrows readily eat birdseed including millet, milo, and sunflower seeds. Urban birds readily eat commercial bird seed. In summer, House Sparrows eat insects and feed them to their young. They catch insects in the air, by pouncing on them, or by following lawnmowers or visiting lights at dusk.
Behaviour
House Sparrows hop rather than walk on the ground. They are social, feeding in crowded flocks and squabbling over crumbs or seeds on the ground. House Sparrows are a common sight at bird feeders; you may also see them bathing in street-side puddles or dustbathing on open ground, ruffling their feathers and flicking water or dust over themselves with similar motions. From living in such close company, House Sparrows have developed many ways of indicating dominance and submission. Nervous birds flick their tails. Aggravated birds crouch with the body horizontal, shove their head forward and partially spread and roll forward their wings, and hold the tail erect. This can intensify to a display with wings lifted, crown and throat feathers standing on end, tail fanned, and beak open. Males with larger amounts of black on the throat tend to dominate over males with less black. When males display to a prospective mate, they fluff up their chest, hold their wings partially open, fan the tail, and hop stiffly in front of the female, turning sideways and sometimes bowing up and down. Sometimes, other males who spot such a display in progress will fly in and begin displaying as well. In flocks, males tend to dominate over females in fall and winter, but females assert themselves in spring and summer.
Nesting
House Sparrows nest in holes of buildings and other structures such as streetlights, gas-station roofs, signs, and the overhanging fixtures that hold traffic lights. They sometimes build nests in vines climbing the walls of buildings. House Sparrows are strong competitors for nest boxes, too, at times displacing the species the nest box was intended for, such as bluebirds and Tree Swallows. House Sparrows nest in holes in trees somewhat less often.
