Flying Geese

Every spring and fall Louisa County hosts hundreds of species of migrating birds. Water levels in the Port Louisa Refuge and Lake Odessa are managed specifically to provide food for the water fowl among these travelers.

How do these birds find their way?

A built in compass and a species specific sense of direction is part of the answer, but recent research suggests their sense of smell may be even more important. (Click here to read about it.)

Which leads me to wonder, what does Iowa smell like to a bird?
