## Physical Characteristics
### Description:
The house sparrow is a small bird known for its somewhat plump body, small feathers, and short yet powerful beak. As one of the most widespread birds, it has long been associated with both rural and urban landscapes, often seen flitting between gardens, rooftops, and city streets.
### Size:
**Length:** The house sparrow typically measures between 14 and 18 centimetres.
**Weight:** On average, adults weigh around 24 to 40 grams, with the maximum being about 42 grams.
**Largest size found:** Males are usually slightly larger than females, with the largest documented birds weighing up to 42 grams and measuring 18 centimetres.
**Smallest size found:** Smaller individuals can weigh just under 24 grams and measure close to 14 centimetres.
### Body and Coloration:
Male house sparrows are characterised by their rich brown upper bodies with streaks of black, grey crowns, and distinctive black throats. Females, however, tend to be more subtly coloured, with grey-brown feathers all over, lacking the prominent black bib present in males. Both sexes have black beaks, short yet sturdy legs, and dark brown eyes.
### Distribution:
The house sparrow is found across a wide geographic range, covering most of Europe, Asia, and even parts of Africa. It has also been introduced to regions like North and South America, Australia, and New Zealand. Originally native to the Middle East, the house sparrow has successfully adapted to various climates and habitats worldwide.

## Habitat and Behaviour
### Habitat:
House sparrows are one of the most adaptable bird species. They thrive in a diverse range of habitats, from rural farmlands to urban cities. Most commonly, they’re found in areas close to human habitations, including parks, gardens, farms, and even city centres. They naturally prefer places where food and shelter are readily available.
### Diet:
Primarily granivorous, the house sparrow’s diet is made up of seeds, grains, and weeds. However, they are also known to eat insects, especially during the breeding season when extra protein is needed to feed their young. In urban areas, house sparrows are opportunistic feeders, consuming food scraps such as bread and crumbs discarded by humans.
### Behaviour:
House sparrows are sociable birds, living in colonies and often seen foraging in large flocks. They communicate through a series of simple chirps and cheeps. These birds exhibit some degree of ingenuity, frequently building their nests under the eaves of buildings or taking advantage of man-made structures for shelter.
### Lifespan:
In the wild, house sparrows typically live for about 3 to 5 years, but some individuals have been recorded living up to 12 years. Urban sparrows might encounter more hazards, limiting their lifespan in more built-up areas.
### Reproduction and Life Cycle:
House sparrows breed throughout much of the year, depending on the local climate. Females lay clutches of 3 to 7 speckled eggs, which hatch after about 11 days. Both the male and female help in feeding the young, and sparrows often have multiple broods per year. Once fledged, juveniles leave the nest within a couple of weeks, but may still rely on parents for food for a few days.
### Predators:
House sparrows face various natural predators such as domestic cats, hawks, and larger birds like crows. Egg and chick predation is often carried out by squirrels and snakes, where environments allow.
### Adaptations:
One of the most notable adaptations of the house sparrow is its ability to live in urban environments. They’ve become highly skilled at scavenging for food discarded by humans. Their compact beaks allow them to crack seeds and consume a wide selection of foods, making their diet highly flexible.
### Relationship with humans:
For centuries, house sparrows have shared space with humans, benefiting from proximity to agriculture, as well as urban areas where food is plentiful. While generally seen in a positive light, some farmers and gardeners may view house sparrows as pests, given their penchant for raiding grain stores and crops.

## Conservation Status
**Conservation Status:** According to the IUCN Red List, the house sparrow is classified as “Least Concern”. However, in certain regions, notably the UK, house sparrow populations have seen a precipitous decline in the last 30 years.
**Threats:** One of the primary threats to house sparrows is habitat loss, particularly in urban areas where older buildings (a favourite nesting site) are torn down or renovated. Pesticides and pollution can also negatively impact their food sources, reducing insect populations vital for their young during breeding seasons.
**Conservation Efforts:** Various conservation groups in the UK and elsewhere are studying the reasons for the species’ decline. Initiatives such as creating sparrow-friendly habitats, building nest boxes, and reducing pesticide usage are in place to encourage population recovery.

## Additional Fields
### Interesting Facts:
– House sparrows are among the world’s most widely distributed bird species.
– They have a close affinity for human habitations and thrive in city centres just as comfortably as in rural areas.
– The typical house sparrow chirp has remained largely unchanged over centuries despite living in different areas of the world.
### Cultural Significance:
Throughout history, the house sparrow has appeared in urban folklore and symbolism. In Christianity, sparrows are referenced as a reminder of God’s will to care for all creatures, no matter how small.
### Economic Importance:
House sparrows contribute to the ecosystem primarily by controlling insect populations, especially during their breeding season. However, they may also negatively impact crops by feeding on grains.
### Threats and Conservation Efforts (Detailed):
In urban environments, the destruction of older buildings has led to fewer nesting areas. In agriculture, the spread of monoculture and use of pesticides is a considerable threat. Conservation efforts include community workshops on creating sparrow-friendly spaces and educational campaigns to discourage pesticide use.

**1. Why are house sparrow populations declining in the UK?**
Urbanisation, habitat destruction, and the decline of crucial food sources due to the use of pesticides are major factors contributing to the decline of house sparrows in the UK.
**2. Are house sparrows beneficial for the environment?**
Yes, house sparrows play an important role in controlling insect populations, particularly during the breeding season when they feed insects to their young.
**3. How long do house sparrows typically live?**
In the wild, house sparrows have an average lifespan of 3 to 5 years, although some individuals have been documented living up to 12 years.
**4. Can house sparrows thrive in urban areas?**
Yes, house sparrows are highly adaptable birds and can flourish in urban environments, taking advantage of human infrastructure for nesting and finding food.
