Size: 14 cm | Habitat: Garden Birds | Season: All year
Once the most common bird in Britain, the house sparrow is a stocky, sociable bird that lives closely alongside people. Males have a grey crown and black bib; females are plainer sandy-brown.
Male: grey crown, black bib, chestnut sides to head · Female: streaky brown above, plain buff below · stout, seed-eating bill
House sparrows are highly social, living in noisy colonies around hedges and roof eaves, and love a communal dust-bath. Numbers have fallen sharply in towns and cities in recent decades.
House sparrows have travelled with people for thousands of years and are now found on every continent except Antarctica.
The House Sparrow (Passer domesticus) is a stocky, sociable bird that has lived alongside people for thousands of years, with males showing a grey crown and black bib and females a plainer streaky brown. Rarely seen alone, house sparrows form noisy colonies around hedges, roofs, and eaves, and enjoy communal dust-bathing in dry soil.
They feed on seeds, scraps, and, crucially, insects during the breeding season, which chicks need for protein-rich growth. Their close association with human settlements has made them one of the most widely distributed birds on Earth, found on every inhabited continent.
Understanding the house sparrow reveals how a bird once considered impossibly common can decline dramatically even while remaining familiar, showing that abundance is never a guarantee of long-term security.
🔴 Conservation status: Red (UK Birds of Conservation Concern 5)
Red-listed. UK numbers have fallen by around 70% since the 1970s, with especially steep urban losses, and roughly 30 million birds are estimated to have disappeared nationwide. Likely causes include a shortage of insect food for chicks, loss of nesting sites in modern buildings, disease, and garden pesticide use — leaving patches of long grass, ivy, and insect-friendly planting can genuinely help.
