which animal has been filled with GPS and why?
Answers
Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern, insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds,and many other species navigate effectively over shorter distances.
Answer:
* First, a GPS receiver is attached to a large collar, which will be fastened
* securely around an elephant's neck.
* The team selects an adult male and fires a dart filled with a drug that will * send him to sleep.
* While he is asleep, researchers attach the collar.
* They need to work quickly so they can get out of the way before he wakes up.
* The GPS receiver will pick up signals from the satellites and calculate the elephant’s position at regular intervals as he moves around.
* This information will then be sent to one of the researchers computers and plotted on a map.
* The red crosses on this map show the changing positions of an elephant that has been tracked for several days.
* Joining up the crosses reveals the elephant's route.
* Using GPS to track wildlife, such as elephants, can help to identify important pathways and watering holes.
* It’s hoped that if these areas are reserved for the elephants alone, people and elephants will be able to stay out of each other's way, reducing the risk of attacks.
* When the elephant wakes up it takes him a while to get used to the collar.
* But he is soon back on his feet and researchers can watch every step of his journey.
* GPS is used to track wildlife.
