This documentary follows Dr. Stuart Houston, an expert on the Swainson Hawk. Living on the prairies during the summer, this bird flies 11,000 km to Argentina for the winter. These majestic birds are facing a serious threat: toxic pesticides. Houston and his team use satellite technology along with traditional bird-banding to greatly increase our knowledge of the lives of migratory birds.
