Deactivated: Arctic Bird Migration Protocol
The Arctic Bird Migration Protocol observed the first arrival of selected bird species at a study site and counted the numbers until few or none of these birds were seen. In this protocol, students used binoculars or telescopes to scan a study site and counted how many birds of a selected species they could see.
