Yes, Birds are believed as well as other animals to have an innate sense of direction, or a "built-in compass" by earth's magnetic field. Concerns have arisen about electromagnetic interference with their internal compasses and our radio and other electromagnetic transmissions, such as the theory of why Bees are seemingly disappearing.
Its an internal instinct, and some scientists say it has something to do with the Earths magnetic pull.
No!
Turkeys are not migrating birds because they can not fly ant have enough fat in their bodys to survive the winter.

Try looking into magnetic balance of the earths rotation. The same thing birds find there way. The planets are to line up soon. Maybe the bees sence of direction is some how being interfed with?
I was taught in college that some animals, such as birds, geese, are guided by magnetic forces, not forcing them to go this way, but guiding them
birds are in a v shape.
