What food does the house swallow mainly eat, and what food does the house swallow eat

Swallows feed on mosquitoes, flies and other insects, and they have always been accustomed to preying on flying insects in the air, and are not good at searching for insect food in tree crevices and ground gaps, and are well-known beneficial birds.

Wild swallows like to eat mosquitoes, flies, locusts, butterflies, moths, earthworms, green worms, grasshoppers, etc.

Captivity can occasionally be fed with vegetable leaves or other grains, such as rice, wheat, etc.

But under normal circumstances, swallows can not be artificially bred, they generally do not eat human food, forcibly open their mouths to feed may not be very smooth, wild and untamable, many times will starve to death, if you pick up injured swallows, it is best to release them after the injury.

The distribution of many swift species has expanded due to the fact that as they increasingly use buildings as nesting sites, these birds have been introduced to areas previously unknown to them. For example, the range of the red-fronted swiftlet has expanded southward to Kenya and Tanzania, and the burrowed swiftlet has moved from Mexico to the southern United States. Changes in the environment can also lead to changes in distribution patterns.

The British population of the swiftlet wintered in South Africa, where it has now expanded westward due to increased rainfall in the west. [1]

Food. All swallow species almost exclusively feed on aerial invertebrates, mainly insects. Plant-based foods are found in only a few types of foods and are consumed in small amounts.

Only bicolor tree swiftlets regularly ingest plant-based substances (mainly berries) and this only occurs during periods of insect scarcity. Swallows are not opportunistic foragers, flying around aimlessly and eating plankton randomly into the air with their mouths open. Instead, they take the initiative to hunt specific prey.

Species with a colidious distribution tend to specialize in preying on invertebrates of different body sizes. In the case of a particular species, it often chooses the largest prey it can get. The diet of migratory bird species in their wintering grounds is usually different from that of their breeding grounds.

For example, when house swallows overwinter in Africa, the proportion of ants in their food increases. In addition, the degree of foraging preferred by a species can vary between wintering and breeding grounds. These changes are thought to be the result of the competition between these migratory birds and the resident bird species that spend their winters.

Swallows mainly eat mosquitoes, flies, locusts, etc., and will also eat seed-based foods, such as rice, wheat, etc. Swallows are known to be beneficial birds because they are accustomed to preying on insects in the air and are not good at searching for insect food in tree crevices and ground crevices.

Swallows are one of the most flexible passerine species, mainly feeding on insects, nesting in tree cavities or crevices, or burrowing in sandy banks, or sticking mud to the walls or protrusions of corridors, roofs, eaves, etc. in urban and rural areas, mainly distributed in southeastern Asia, northern and eastern Africa, and most of Europe.

The house swallow (scientific name: hirundorustica), also known as the swallow, is a bird of the family Swallowidae. House swallows are small birds with a slender body length of 15 to 19 cm, a weight of 14 to 22 g, and a wingspan of 15 to 19 cm.

forehead dark chestnut; The upper body feathers are blue-black with a metallic sheen; chin throat and anterior thorax chestnut red; White abdomen. The tail is deeply forked, long, and forms a "dovetail". <

a.Flying insects.

b.Plant fruits.

c.Rice grains, nuts, etc.

Correct Answer: a

Answer analysis: Swallows are nature's beneficial birds, mainly mosquitoes, flies and other insects as their staple food, and can eat 250,000 deficit insects in a few months, so people can't hurt it. In the autumn before winter comes, the swallows make their annual long journey—flying in flocks from the north to the far south, where they enjoy the warm sunshine and humid weather, leaving the frost and bitter cold winds of winter to the chickadees, grouses, and ptarmigans, which never fly south for the winter and drains.

House swallow is a common bird and is also known as mountain swallow or cave swallow. They belong to the category of typical insectivorous birds and feed mainly on insects. Here's some information about the house swallow diet:

1.Insects: House swallows mainly eat a variety of insects, such as flies, mosquitoes, moths, spiders, small beetles, etc. They fly quickly and catch insects in the air, so they can often be seen in farmland, near lakes, rivers, etc.

2.Cobwebs: House swallows sometimes eat cobwebs. They will catch small worms in the cobwebs and then devour the entire web. This behavior is uncommon and usually occurs when the food supply is low.

3.Aquatic insects: House swallows near water often eat aquatic insects, such as daphnia, water mosquito larvae, etc. They will fly low or hover over the water to catch insects in the water.

4.Moths: House swallows also eat some moths at night. Moths move around the light, and house swallows will take advantage of this opportunity to catch them.

It should be added that house swallows are often raised in captivity in farms, so proper feed needs to be provided when raising house swiftlets. Common house bird's nest feeds include baby bird meal, insect larvae, swallow feed, etc. Specific feeding methods and feed formulas can be consulted with breeding experts or refer to relevant breeding guidelines according to the specific situation.

Generally speaking, house swallows are birds that mainly feed on insects, eating a variety of common insects and aquatic insects. Their feeding habits adapt to their predatory behavior in different environments. <>
