What distinguishes swifts from swallows: the main characteristics
These little ones are familiar to everyone. This refers to the swift and swallow, about which we will conduct a conversation. They spend their lives near a person. With the arrival of spring, they fly to the dwellings of people, giving joy and good mood.
Many have seen birds hovering over residential quarters that perform complex pirouettes. Since childhood, we were taught that the swallows and swifts the tail with a fork. Then what is the difference between swifts and swallows?
At first glance, these two birds are very similar, but learning to distinguish them is quite realistic. Ornithologists attributed these representatives of the fauna to different orders.
- Swifts - representatives of the order of the swift (the second name - long-winged).
- Swallows are attributed to the order of passer-shaped.
What can explain their external similarity? The main reason is a similar method of food extraction. They feed on insects that are caught during the flight.In this case, the technique of moving in the air, they must be very good. This is facilitated by excellent aerodynamics, low weight and the corresponding shape of the wing. The structure of the tail is ideal for making difficult maneuvers in flight. But not all people know how to distinguish a swift from a swallow.
Both species of birds became professionals in their field. The maximum recorded speed of flight swift - one hundred and sixty kilometers per hour. Such a rhythm of life does not prevent them from catching insects and water drops on the move, as well as sharing food with chicks following their parents. Scientists established the fact: Swifts are able to sleep while in the air. Here are such interesting birds swifts and swallows.
One can distinguish one bird from another by the color of the plumage. During the flight, this is of course problematic. The plumage of swallows casts a blue-black gamut of colors. Breast beige or snow-white. The head is covered with imitation caps, which has a light brown color. In the cap there is a collar.
The plumage of swifts is distinguished by dark tones, which are cast in a greenish tint. They also have a small white spot on their neck and under their beak.Swifts, as a rule, have a greater weight and size than swallows. Now you know the difference between swifts and swallows.
Representatives of both groups - migratory. Sometimes in early April, you can meet the first swallows who returned to their native lands. But the swifts fly only when the nose is summer and the warm weather is finally established. It happens in the last days of May. People sign says: swifts appeared - the warm weather was established for a long time. That's just how to distinguish swift from swallows to interpret popular superstitions?
Let us examine the flight of these birds. Birds spend a lot of time in the sky, so we see them mostly there. Swallow's flight speed is much lower than swift. It is a pity that it is not possible to measure this indicator without special devices. Reliably focus on the characteristic movements and behaviors in the sky. The flight of a swift is very predictable, straightforward and lightning-fast. With one trajectory, it can sharply drop into its nest. The swallow will not be able to predict the route of movement due to the abundance of maneuvers.
Externally, swifts and swallows have similarities, but the behavior of birds is different.Scientists can easily determine which bird is in the sky by seeing the games in the air.
You can distinguish swallows and swifts by the sounds they make. That which can be heard from the swift is difficult to call singing. Rather, they shout or scream: “Sleep-sleep” or “Kri-Kri”. And the melodic singing of a swallow is not to be confused with anything. At the end of her singing, a trill is heard. Listening to them is a pleasure.
Voice and sounds are the main differences between swallows and swifts. That is why many people prefer to see the nests of swallows near their homes.
Where do birds prefer to live?
Swallows almost do not appear in the urban landscape, but the swifts here are well accustomed. Their cry during the flight has a very specific purpose - echolocation. Outgoing sound is reflected from obstacles and perceived by the bird. Based on the information received, she builds a picture of the surrounding space. This method helps the swifts to avoid collisions with houses, other objects and with each other. This is how swifts differ from swallows.
Some have seen the following picture: a small swift flies home through the window and cannot get out.This sin chicks who are still learning to navigate in the air. He could miss the open window and then he would die. It is easy to help an inexperienced flyer: it is enough to let it out of the vents outside. He will fly back home.
One of the important distinguishing features of swifts is that they almost never sit on the ground, branches or other objects. They are able to grasp a minor knot, crevice or other object and hang on it upside down. In this position, they usually sleep.
This ability is dictated by the structure of their paws. Both birds have paws on four fingers. However, the swallow has one of the fingers pointing back, while the swine has all four - forward. The paws of the swallow have the most common structure, which allows them, like other birds, to easily walk on the ground and sit on the branches. Now you know the difference between swifts and swallows.
In nature, all species are unique. Many have similar traits due to their lifestyle. But if you look at them more closely, you can easily distinguish them. Swifts and swallows are a great example of such similarities and differences.
