Introduction to Bird Banding

Bird banding has been used to study wild birds since the late 1800s. Data obtained at banding stations has greatly increased understanding of bird migration and anatomy. Banding stations are placed in sites where birds congregate in large numbers during migration. These stopovers generally have excellent habitat that offers food and a safe place to rest. Scientists set up a series of mist nets to harmlessly trap birds. When a bird is removed from the net, its leg is fitted with a small metal band, and the bird is weighed and measured to evaluate its condition. Each band has a unique number on it so that if the bird is recaptured or found later, scientists will know when and where it was banded. Banding stations also serve as outdoor classrooms to enhance public appreciation and awareness of birds. The stations provide valuable opportunities for volunteers and students to gain experience in scientific field techniques. Bird Conservancy of the Rockies conducts banding at two stations each spring in Colorado and five stations each fall in Colorado and Nebraska. Teachers and group leaders can arrange a visit for groups of students and individual visitors are welcome. For more information, visit https://birdconservancy.org/what-we-d...
