The House Sparrow is one of the most common bird species in the UK, with an estimated population of around 5 million breeding pairs.

However, the bird’s population has declined significantly in some urban areas, with a decline of around 70% in London between 1994 and 2004.

House Sparrows breed between April and August, with females laying a clutch of 3-5 eggs in a nest made of twigs, grass, and feathers.

The eggs are incubated for around 11-14 days, and the chicks fledge after around 14-16 days.


House Sparrows are found in a wide range of habitats, including gardens, parks, farmland, and urban areas.

They are particularly common in areas with a mix of grassland, shrubs, and trees, which provide them with shelter and nesting sites.



The House Sparrow is primarily a seed-eating bird, feeding on a variety of plant materials such as cereal crops, grasses, and weeds.

They may also eat insects and other small invertebrates, particularly during the breeding season.
