House Sparrow

Adult males feature a dark grey crown, black bib, chestnut brown nape, and white cheeks. Females and juveniles are duller, with grayish-brown upperparts featuring buff streaks and a pale eyebrow stripe (supercilium), lacking the distinct head pattern and black bib of the male.

Conical yellow-tinged or black bill (depending on season), stout body, grayish-brown back with black streaks, and lack of bright plumage in females/juveniles; male easily identified by black bib and grey crown.

Length: 14-18 cm (5.5-7.1 in), Wingspan: 19-25 cm (7.5-9.8 in), Weight: 24-39.5 g (0.85-1.39 oz)

A repetitive, monotonous series of chirping notes, predominantly 'chirrup' or 'chissick' calls.

Primarily seeds of grains and weeds, but also eats scraps of human food, flower buds, nectar, and insects (especially during breeding season).

Urban and agricultural areas, towns, cities, farmyards, and villages; rarely found far from human settlements or cultivation.

Non-migratory resident bird, though juveniles may disperse short distances to find new territories.

Constructs a messy, dome-shaped nest of dry grass, feathers, and string in building crevices, tree cavities, or nest boxes. Clutch size is typically 3-7 white to bluish-white eggs speckled with brown, raised by both parents across multiple broods per year.

Tree Sparrow (Passer montanus), which has a chestnut crown and a black cheek spot lacking in the House Sparrow; and various American sparrows (Passerellidae), which are generally slimmer and less tied to human structures.

Acts as an important seed predator and prey species for urban raptors and cats; also helps control insect populations during the breeding season when feeding nestlings.

IUCN Least Concern; population trend is generally stable or decreasing slightly in some urban European areas due to habitat changes.

Look around urban parks, farms, cities, and suburban backyards near human structures and bird feeders.

House Sparrows dust-bathe frequently in dry soil or loose sand to help maintain their feathers and eliminate parasites. They were intentionally introduced to Central Park in New York City in 1850 to combat insect pests.
