Living on the prairies during the summer, the Swainson Hawk flies 11,000 km to Argentina for the winter. But toxic pesticides pose a serious threat to these majestic birds. Dr. Stuart Houston and his team use satellite technology along with traditional bird-banding to greatly increase our knowledge of the lives of migratory birds.
