The swallow birds are widely distributed. Its scientific name is Hirundo rustica. It is an insectivore. Insectivores mean, they feed on various types of insects. A large reduction in their population has been observed in North America. The feeding habits of birds are most important for humans because they eat insects, so they are a great source to control the insect population in a specific area. They are found near human homes.
Feeding behavior
Swallows are insectivores. The word insectivores mean the organisms which mainly feed on insects. They like to eat the insects of various orders, like the order Diptera. Swallows identify their prey from their wings. Which insect will be preferred depends upon the prey size. Swallows increase their flight speed when they are following their prey. They catch their prey during flight. Their prey may be small or big, but they mainly catch insects that are small in size because it is too easy for a bird to pick them up and swallow them. Swallows can be found near water reservoirs like canals, rivers, ponds, or lakes. They live in trees in their nest. Here, double insects can be found, aquatic and terrestrial, so there are minimum chances of population reduction of insects.
In the areas near the water bodies, there are a lot of aquatic insect populations, so the swallow birds can easily find insects to eat in their meals. These birds fly over water bodies. They sometimes find their prey on their first flight, but in some cases, they have to fly over the bodies of water several times. They twist their bodies in the sense of catching an aquatic insect. They just feed on flying insects. In order to prey on terrestrial insects, they also fly over the deserts. They make long rounds over the deserts in search of terrestrial flying insects. When they move through the deserts, they face low energy supplies to their organs to fulfill their efforts in catching insects or better growth and development. When they travel across deserts in search of insects or food, they are usually uninterested in eating or drinking anything. Swallows like to eat insects that have these qualities.
- The insects should be small in size.
- Insects should be light in weight.
- Insects must have less strength to fight.
What do swallows eat?
The swallow birds’ favorite food is flying insects, even if they are aquatic insects or terrestrial insects. As we have already discussed, swallows feed on different orders. Here are the orders and the percentage of insects, selection of different order. For the maintenance of digestion, swallows also eat small pebbles and egg shells.
| Order | Consumption percentage |
| Diptera | 31 % |
| Hymenoptera | 40 % |
| Hemiptera | 15 % |
| Coleopteran | 12% |
Here are some insects which have been selected for feeding.
- Flying insects
- Aquatic insects
- Terrestrial insects
- Flies
- Bees
- Beetles
- Wasps
- Flying ants
- Butterflies
- Moths
Flying insects
Swallows like to eat flying insects, so we can say that swallows are insectivores. They like to eat both types of flying insects.
- Aquatic flying insects
- Terrestrial flying insects
Where do they find the aquatic insects?
As you know, swallows live near the water bodies. They make their insects in trees near streams, lakes, rivers, and canals. They fly over the surface of the water to catch the insects in order to eat them in order to fulfill their needs for growth.
Where do they find the terrestrial insects?
In search of terrestrial insects, they take a very long or maybe slight, round over the desert’s plant or trees. They fly over the Sahara desert, twisting and turning over to catch the insect. In particular, they catch their prey with their wings.
Flies
Swallows mostly like to eat insects from the order Diptera, which includes flies. Swallows consume 31% of insects of the order Diptera.
Bees
Bees are also their favorite food. Because they eat flying insects and bees are also flying insects. Swallows attack bees by catching them by the wings, grasping them in their beak, and then eating them; the bee is easily engulfed.
Beetles
Swallows feed on beetles. They eat beetles to maintain their nutrient needs which helps them grow well.
Wasps
Whenever flies, bees are unavailable they also eat wasps.
Flying ants
Ants are of two types: winged ants and non-winged. They never eat non-winged ants; only winged ants are selected.
Butterflies
Butterflies are small in size, so they catch them easily. They are also light in weight. They find them around their habitats.
Moths
They like to eat moths. The most favorite moths are brown in color.
What do baby Swallows Eat?
Swallows feed their babies on small insects that can be easily engulfed and digested by babies. They are fed by both parents, and they also bring back a portion of the food that they catch, which means that the adults have to work even harder to meet their nutritional needs when there is a clutch of chicks to feed. As a result of the cold weather and because some early nests may struggle during cold springs, adult swallows may go out into the surrounding area in search of berries or whatever birds can collect to feed their babies..
Feeding methods
Birds like to live in groups. For feeding purposes, they also fly in group form. They also go out in search of food in groups. One of them works as a leader and tells them about a large source of feed. The other birds follow their leader, pick food and come back to their home. Now the question is, how do birds come to know that there is a reservoir of food? They release hormones, these hormones help them to communicate about the feed and location.
Every bird in the group has an equal chance of finding and getting food. Every member of the swallow bird has an equal opportunity to provide information about any food source or to inform his group member about this source. Every member of the group has an equal chance to receive the information from that member and follow it to get food. Swallows identify their prey from their wings. Which insect will be preferred depends upon the prey size. Swallows increase their flying speed when they are following their prey.
It attacks its prey by snapping its wings. Sometimes they locate the insects in branches of trees. To find the terrestrial insects, they spend some time in the desert. They come round again and again. They also change their body shape, much like when they bend their bodies to catch the insects. In other words, as they also prey on aquatic insects, they fly over the surface of water reservoirs like rivers, canals, lakes, and streams. Swallows fly over the water surface for the purpose of catching their prey.
