Environmental Education Lecture--Understanding the Migration and Travel of Birds
Environmental Education Lecture – Understanding the migration and round trip of birds
Did you know that birds do not have a nationality? They migrate over long distances, often flying from one country to another, or even from one continent to another, even across half the world. How do they reach their destination accurately? Let's understand how birds use GPS to locate themselves.
Birds have no nationality. They travel a long distance, such as from one country to another, or even fly from one continent to another, moreover, fly far over half of the earth. How did they reach their destination accurately? Let us understand how the bird is flying and positioning with his GPS?
There are three main reasons for the migration of migratory birds:
There are three main reasons for the phenomenon of migratory bird migration::
1. Impact of the Ice Age: During the Ice Age, much of the Earth's northern continent was covered by glaciers, and a large number of insects and plants died. In order to survive, birds were forced to migrate south many times. Every time the glaciers melted, they migrated back to their birthplace. Over time, this formed the instinct of birds and was passed down.

Time over time, formed the instinct of birds and inherited it.
2. Selection of breeding grounds: Birds’ breeding grounds need to have abundant food and necessary safety conditions. Wintering grounds are not suitable for nesting and breeding, so they return to their hometown every spring.

3. Physiological stimulation: The migration of birds is largely determined by the endocrine stimulation produced in the body.
