Okay kiddo, let's talk about how scientists keep track of where animals go when they move from place to place. It's called tracking animal migration, and it's really important because it teaches us a lot about animals and their habitats.
First, scientists need to find a way to attach something to an animal that won't hurt or bother them. Sometimes they use things like radio collars or tags, which are kind of like bracelets that go around an animal's neck or leg. These tags help scientists keep track of where the animal goes by sending signals back to a computer.
Other times, scientists use something called GPS, which stands for Global Positioning System. This is like a special map that shows where the animal is all the time, and it can tell scientists how far and how fast the animal is moving. It's kind of like a really fancy tracker that works all over the world!
There are also special cameras that take pictures of animals when they go by. These cameras are set up in places where animals like to go, and when the animal walks by, the camera takes a picture. Scientists can use these pictures to figure out where the animal goes and how often it goes there.
Tracking animal migration is important because it helps us learn about how animals live in different parts of the world. It helps us understand their habitats and what they need to survive, and it helps us protect them from things that might hurt them. So it's really cool that scientists can use technology to figure out where these animals go!
