Since animals don’t have an alarm system like ours that tells them when they will leave, how do birds migrate to long distances and warm areas during the change of seasons and as they bid farewell to summer? calendar system can they have?

Although this is actually a fascinating example of nature, survival of birds and some of their reproductive strategies. Birds that migrate to different regions to survive owe it to their biological elements to move at the same time every year, as if they had chronometers.

The ability of birds to migrate is one of the most impressive examples of adaptation in nature.

This complex process skillfully combines environmental factors and the birds’ internal biological clock. with perfect timing towards a specific route in the air It allows them to move.

biological clocks, It ensures that birds naturally follow an internal time calendar. Birds, which can sense daily light changes, follow the seasons and begin migrating at the right time.

This is kind of It is an instinctive mechanism. Actually. A mechanism that allows birds to navigate in harmony with the general rhythms of nature, while relying only on their own internal clocks.

Ultimately, we all understand that the sun has set and it is night.

As humans, we can sense this biologically by yawning or getting tired when it’s time to sleep. This situation means we need to rest. have an internal clock comes from the fact.

Just as we biologically have such consciousness and experience it every day, we have a similar consciousness for birds. They have an internal clock We can say. Among the signs of this hour is an important clue for determining the time of migration.

According to experts, one of the biggest clues in determining when birds migrate is… changes in the amount of daylight.

Northern Hemisphere With the arrival of autumn, daylight decreases. Given the shortening of the day that we are experiencing these days, birds are currently spreading their wings towards the south. This situation also occurs in birds with this consciousness.immigration unrestIt is called “.

These changes are called photoperiod and are an extremely important signal for birds.

As the days get shorter or longer, There are some changes taking place in the biochemistry and physiology of birds. The link between day length and migration is known to have deep roots in the evolutionary history of many animals.

So even though birds have inherited the tendency to migrate from their ancestors, they don’t fully understand why they behave the way they do; It’s just instinctive behavior and they think they should.

Bird species affected by the photoperiod are called obligate migrants.

These birds; They begin their movements before weather conditions become difficult and food supplies run out. Behavior that they develop instinctively; It also makes situations such as the distance, timing and return of migration more predictable.

It is also wrong to make a final judgment, as all birds migrate. Because some birds They only migrate voluntarily if they have to survive.

These birds manage their migration practices depending on environmental factors. When weather conditions become difficult or food supplies begin to dwindle, They start flying south.

There are also birds that do not migrate randomly.

The migration of these birds is based on their ability to evaluate environmental factors. Forced migratory bird species influenced by photoperiodthey tend to migrate before weather conditions become difficult, making their migrations very predictable.

So the end of summer The herds we see in the sky are among the forced migrants..

As we have seen, when birds decide to migrate, the rhythm of the biological clock, signals and variables from the environment They provide a beautiful balance between

This complex harmony ensures that birds fly through the air with perfect timing. towards a certain route As they move forward, beautiful images emerge.
