Consider which birds fly to the south, and which remain

All children know that many birds leave their native northern latitudes with the onset of cold weather and go on long journeys to the south. Why is this happening? Yes, because under the thickness of snow it is more difficult to look for food, insects and ants, which you can eat in the summer, and the air temperature becomes too low. However, not all the inhabitants of the heavenly heights leave our latitudes. Which birds fly to the south, and which remain at home - we now consider in detail.

The reasons why birds change their home

Each bird is a representative of the fauna, and at the same time a separate kingdom among all animals. These creations are warm-blooded, their body temperature averages 40 degrees. With the onset of severe frosts, birds begin to feel a lack of warmth, feathers and down are not enough to cope with frosts. However, this situation is not inherent in every species of this kingdom. Sparrows, magpies, crows, tits remain in their places, in temperate latitudes, since the structure of their body, the number of feathers, and also the subcutaneous fat is much higher than that of nomadic celiacs. As a result, answering the question: "Which birds fly to the south?" - we can say that, first of all, those that for physiological reasons can not cope with severe frosts. By the way, if the bird lives in a more southern region (Rostov-on-Don, Belgorod), then it does not leave its lands because of the cold. But if its motherland is Norilsk, then a flight to a more southerly region is an integral part of its life cycle.

Food is an important criterion in choosing a place of residence

Talking about which birds fly south, you should not miss the nutritional factor. Most of them are insectivorous, therefore, in winter their diet is reduced to zero. Birds that feed only on bugs and insects reach the lands where snow does not fall out at all, so that their food remains full. Among them you can distinguish finches, thrushes, jackdaws, rooks. Also actively eat insects oatmeal, mushrooms, dawn. Also, speculating about which birds fly south due to a lack of food habitual for them, you can not miss the swallows. They are in the summer able to eat such large insects as dragonflies, May beetles and their like right on the fly. In winter, they are unrealistic to meet in our latitudes.

Which birds fly south in the fall?

With the first cold weather our country is left by the most thermophilic inhabitants of the sky. Among them we distinguish swallows, rooks, starlings, chizhev, oatkins, cranes, thrushes, larks. Of course, in the warm countries, birds such as herons, cranes, storks, ducks, swans, hoopoes, wild geese, orogs and cuckoos leave as well. The reason for the flight of these birds is a lack of food, in particular, fall into a hibernation or die all the insects that lived in the summer. They are the first of all migratory birds fly to the southern regions and the latter return to their homeland. That's why swallows can be seen on the street only since April. And wild swans return to their lakes no earlier than May.

Consider which birds fly away to distant lands in winter

When the colds have already prevailed, our region of birds can leave only if the frost is too strong, or food such as crumbs, grains, seeds will not be on the streets at all. Often in the warmer countries are sent tits, thrushes, woodpeckers, sometimes our land is left by bullfinches. Such inhabitants of the sky easily tolerate frosts, so the only thing that can make them fly away is the lack of food.
