Putting beacons on birds is not novel. But a new antenna on the International Space Station and receptors on the Argos satellite, plus the shrinking size of tracking chips and batteries, are allowing scientists to remotely monitor songbird movements in much greater detail than ever before.
- Maryland scientists are using technology to track birds, and their migration patterns. A robin is wearing a tiny metal backpack with antenna, that transmit signals to a satellite. Ecologists will track where the bird moves at the end of the season. The goal is to check why some birds travel far, and others do not. While the bird is local, scientists will keep track of its mating and feeding patterns.
