This paper aims at studying the behavior of migratory birds and tracking endangered species of birds like swam, cranes etc using wildlife tracking satellite. Data collected through satellite tracking helps us to understand and protect the endangered and threatened species of the world. Scientists have attached tiny transmitters to wild animals for years, tracking their radio signals with receivers nearby on the ground. Now they track wildlife ranging over much wider areas with receivers high above the ground. A receiver in an orbiting space satellite can hear a transmitter attached to an animal. Even if the animal is out of sight over the horizon from a tracker on the ground, a satellite high in space still can hear the transmitter and repeat its signal down to trackers on the ground. The research comprises of study of factors such as breeding movements, spring and fall migration of migratory birds.
