I live a mile from the Pablo Wildlife (wildfowl) Refuge. It seems that sometimes the crows or ravens I see just fly for fun. You can't explain their amazing flight patterns, especially in pairs (!) as "looking for food". The pairs so often look like synchronized flying and then somersaults in mid air like Roller Pigeons (my neighbor has 50 Roller Pigeons). Maybe this course will talk about this flying-for-fun thing
