The migration of birds is one of its most surprising biological characteristics. All migration is marked by the biological clock of each species of bird, depending on its climatic, nutritional and / or reproductive needs. However, it is important to note that not all bird species that inhabit the length and breadth of the planet feel the need to migrate, since many are also birds capable of remaining in their natural habitats, as long as they have sufficient adaptation. to survive in its habitat throughout the year, also having the nutritional and reproductive needs covered without problems.

What are migratory birds and their characteristics
To the group of migratory birds belong all those species of birds (flying and non-flying, aquatic or terrestrial), which move year after year, at the beginning of a certain season, to reach other regions of the planet where they can satisfactorily cover their nutritional and reproductive needs .
Among the main characteristics of migratory birds we find:
- Strong and robust anatomy that allows them to travel thousands of kilometers.
- Immune system adapted to the possibility of contracting diseases and parasites while traveling from one country or continent to another.
- Ability to change their physiognomy, to adapt optimally to the environmental changes that they usually suffer during their routes.
- Impressive sense of direction.
In the next section we will see in more detail the magnificence of their sense of orientation , as well as all the surprises that the migration process hides under the wings and brains of migratory birds. In addition, in this other AgroCorrn article you can learn more about which animals migrate and why they do so , since birds are not the only ones with this behavior.
How is the migration of birds
Without a doubt, the migration of birds is a natural phenomenon that leaves no one indifferent, since doubts like these arise: how are they able to recognize the destination of their migration and be clear about both the direction and the path of their travels? And, even more interesting, how do migratory birds know that the right time has come to change countries or even continents?
The answer lies in the genetic information they possess, which makes it possible for all migrating birds to have developed the ability to migrate across the globe. For this they use internal sensors that, forming part of the biological clock of the animal, allow the control of its movements according to the synchronization with the solar clock. They thus use information from the sun, as well as from “celestial compasses” (the moon and the stars), as well as from the Earth’s magnetic field. Subsequently, by processing all this information, they are able to create a cognitive map that allows them to orient themselves at all times during their migration journeys.
Thanks to the capacity of learning and memory that migrating birds have, each year, when spring or autumn arrives, they are ready to venture again and migrate in search of food and warmer temperatures.

Now that we know the main characteristics that all migratory birds in the world share, as well as how the migration process works, let’s take a closer look at some of the many birds that migrate.
