About chipmigration

The Calgary Bird Banding Society is a non-profit research organization conducting the third year of a landbird monitoring project at Cypress Hills Interprovincial Park, Alberta. Bird banding is an integral aid to the study and protection of wild birds. It is typically facilitated by using a mist net. Birds fly into the mist net, are gently removed and a permanent aluminum light-weight band is placed around the lower leg. Often the birds are measured, weighed, sexed and aged before release back into the wild. When a banded bird is recovered, the number and information on the band is used to trace migratory patterns and other vital data. This information made available to the banding and scientific communities. The data is invaluable to many scientific studies, including Global Warming and Pollution research.
