How do ornithologists study birds and migration?
Bird banding or ringing is one method used to study wild birds. Scientists attach a small individually numbered metal or plastic ring to a bird’s legs or wings. They also use mist nests as a way to capture birds. This way they can capture and re-capture the same individual and measure and weigh it and gather other important information. Here are excellent photos of that process. Sometimes scientists use satellite tracking for follow birds on their migration routes.
