The Tetlin National Wildlife Refuge is situated in the eastern Boreal Forest of Alaska, along an age old migratory bird route known as Tetlin Passage. Established in 1980, your refuge welcomes nearly 200 species of birds each spring; some to stay and nest for the summer and some to travel further into the state. Because this migratory passage is the flyway for sand hill cranes and a critical nesting area for trumpeter swans, it is recognized as an Important Bird Area by the Audubon Society. 
Summer is a busy time for our biologists; capturing, banding and surveying birds. Winter is just as busy for them as they record their findings. Below are some links to some of these studies.
