House sparrows, or Passer domesticus, are one of the most common birds in Australia, but their numbers have been dwindling in recent times. The birds were introduced to Australia from Britain between 1863 and 1870, but new research shows that they first arrived from India in 1862. House sparrows are considered pests due to their consumption of agricultural products, but they can also be beneficial to humans by eating insect pests. So, what do these sparrows eat?

What You'll Learn
Insects
House sparrows are considered pests due to their consumption of agricultural products and their ability to spread disease to humans and domestic animals. However, they can be beneficial to humans by eating insect pests.
House sparrows were introduced to Australia as an early form of bio-control, to help control the number of insect pests. They were also thought to help the struggling agricultural sector. In 1860, Edward Wilson, editor of the Melbourne Argus, called for farmers to "wage war" on insect pests with the help of sparrows. Studies in Switzerland showed that while sparrows do cause some damage to fruit crops, this is outweighed by the number of insect pests they feed to their nestlings (3,000 per nest).
House sparrows are known to eat a wide range of foodstuffs, including insects, spiders, berries, seeds, flower buds, and scraps of food discarded by humans. They are also known to scavenge for food in garbage containers and congregate outside restaurants and other eating establishments to feed on leftover food and crumbs.
House sparrows are highly adaptable and opportunistic, eating whatever foods are available. They can perform complex tasks to obtain food, such as opening automatic doors to enter buildings. They are closely associated with human habitation and can live in both urban and rural settings.

Seeds
House sparrows are closely associated with humans and are considered pests because they consume agricultural products. They are known to scavenge for food in garbage containers and congregate outside restaurants and other eating establishments to feed on leftover food and crumbs. They also eat seeds, grains, weeds, and vegetable matter, as well as bread, grass, and weed seeds. They will also consume flowers, buds, fruits, and insects.
Sparrows are opportunistic and adaptable, eating whatever foods are available. They are known to perform complex tasks to obtain food, such as opening automatic doors to enter supermarkets and clinging to hotel walls to access balconies. They require grit to digest harder items in their diet, which can be in the form of stone, grains of masonry, or the shells of eggs or snails. Oblong and rough grains are preferred.
Sparrow diets include a variety of seeds, including vegetable matter, bread, grain, and grass, and weed seeds. They will also eat seeds from agricultural crops, such as grains and oilseeds, which has led to them being considered pests in some areas. They may also eat seeds from flowers and buds, as they have been observed to consume these plant parts as well.
Sparrows are known to feed on a wide range of seeds, including those that are easily accessible in urban and rural areas. They may forage on the ground along walkways, near rubbish sites, and in open areas, typically in small groups of fewer than 20 birds. This behaviour suggests that they are able to find an adequate food supply in a variety of habitats, which may contribute to their success as a species.

Scraps of human food
While it is important to note that not all human food is safe for birds, sparrows are known to eat scraps of human food. House Sparrows, in particular, are considered pests due to their ability to feed on a wide range of foodstuffs, including scraps of food discarded by humans. They are also known to enter canteens and other buildings to scavenge for food.
Bread crumbs, a common household scrap, are often consumed by sparrows and other birds. However, it is important to offer these in small amounts and not as a staple food source, as bread has no nutritional value for birds and can cause health issues if consumed in large quantities. Bread crumbs can also be difficult for larger birds to eat and may blow away in the wind, so it is recommended to soak them and mix them with seeds and peanuts to provide a more substantial offering.
In addition to bread crumbs, sparrows may also feed on other human food scraps such as insects, spiders, berries, seeds, and flower buds. It is important to prioritize natural bird food sources, such as seeds and nuts, to ensure that sparrows and other birds obtain the necessary nutrients for their health and well-being.
While it may seem harmless to feed birds with human food scraps, it is essential to prioritize their nutritional needs and avoid potential health risks associated with certain human foods.

Berries
House sparrows are not native to Australia and were introduced to the continent in the 1860s by European settlers, primarily from Britain. They have since established populations across the country, especially in urban and rural areas. House sparrows are highly adaptable and thrive in human-modified environments, taking advantage of food sources such as grains, seeds, and scraps. They are closely associated with humans and are known to feed on a wide range of foodstuffs, including insects, spiders, berries, seeds, flower buds, and food scraps.
House sparrows occasionally supplement their diet with fruits and berries. They may feed on ripe fruits, berries, or even nectar from flowers. They are also known to exploit food sources provided by humans, such as grains, seeds, and scraps. House sparrows are opportunistic feeders and can adapt to various food resources, making them highly adaptable in urban and agricultural environments.
In addition to hawthorn berries, house sparrows have been observed eating the tiny, bright red berries of a shrub in the UK. They also consume the berries of Pyracantha, which are commonly grown as ornamental hedges. These berries are not just useful for adding variety to the diet of birds but also for providing natural foods that offer health benefits. Berries are a good source of antioxidants and vitamins A, B, C, E, and K, as well as important minerals such as potassium, manganese, copper, iron, and magnesium.

Flowers
House sparrows are omnivores and will eat a wide variety of foods, including flowers, buds, fruits, seeds, grains, insects, and even scraps of human food. They are considered pests in Australia, but their ability to feed on a diverse range of foodstuffs has contributed to their successful establishment in the country.
Sparrows are particularly fond of seeds and grains, and they will eat almost any type of seed, although they show a preference for corn, oats, wheat, and maize. They are also known to eat the seeds of flowering plants and weeds, as well as commercial bird seeds. In urban areas, they tend to rely more on food provided by humans, such as bread, although they prefer raw seeds.
The house sparrow's diet also includes flower buds and some plant matter, such as berries, grapes, and cherries. In temperate areas, they have been observed tearing flowers, especially yellow ones, in the spring. This behaviour may be related to their search for nectar or insects, which are another important part of their diet.
The house sparrow's insect diet includes beetles, caterpillars, flies, aphids, spiders, and various non-insect arthropods. They will also eat molluscs, crustaceans, earthworms, and even small vertebrates like lizards and frogs. This diverse diet, combined with their adaptability and opportunistic nature, has contributed to the house sparrow's success in Australia and worldwide.
