Fact #46

Did you know that the Regional bird on every generation, you first encounter at the start of the games will always be a normal/flying type even when it evolves.

There's yet to be a pure flying type Regional bird.

*Spoiled X and Y Fact*

The Kalos Regional bird Fletchling will change that trend, when it evolves into Fletchinder then Talonflame, it will become a fire/flying type.
