Migration – How Do Those Birds Do It?

Bird migration is an amazing phenomenon. Some birds fly non-stop for several days, while others interrupt their journey at pit stops. Bird migration is a complex phenomenon that has not yet been fully studied by scientists. The simplest explanation is that migration takes place in search of food and ideal breeding grounds.

To prepare for a long journey, birds need to accumulate abundant reserves of fat. They chew (or peck) a lot of food to replenish their bodies on a difficult journey.

Migration routes are established depending on the species of migratory birds and the migration zone. In summer, many birds migrate from the northern nesting areas. Some migratory birds move to the southern winter territories, as there is a lot of land. There are many other bird migration patterns. Some birds even fly long distances, reaching the southern tip of South America, Australia, Africa and Asia, and then heading to the northern wintering grounds. Some birds migrate horizontally, while others migrate in height, moving higher in summer and lower in winter.

In addition to food, migration is strongly influenced by wind and ocean currents. Birds use the wind to their advantage to be able to travel long distances and minimize fuel and energy consumption. Birds also orient themselves according to the position of the sun during the day and the stars at night. Birds sense the north. Other factors that influence the route include the appearance, smells, and sounds they hear.

There are several main routes for عظمة الهدهد to go south and return north. Its main air route runs over the central United States and the Mississippi River. Some birds fly at night and rest during the day; other birds do the opposite. Birds flock to these long flights, and some of them, such as wild geese and ducks, even fly in regular formation. The great thing about bird migration is how they can know direction and how they will always return to the same places they left in the previous season. Some birds even return to the same nest or nesting site. Man still does not know how they do it.

Unfortunately, not all birds survive on their journey. They must withstand storms, bad weather and other natural obstacles. In addition, migratory birds face everyday problems caused by humans. Humans are devastating the natural habitat of birds by draining wetlands, polluting the environment and deforestation. People hunt many birds for food or sports. Man-made buildings such as illuminated skyscrapers and lighthouses are highly distracting, tricking and killing birds. Regardless of whether these actions are carried out deliberately or not, this is a sad situation that we face. Many birds and animals have become extinct due to our dangerously reckless actions, which greatly affect the environment.
