Why is there only one single-Flying-type Pokemon?

Yeah, that pretty much explains it.

Because most of them are birds.And, birds are prettyNormal.

Like, excluding the ones like Butterfree and Gyarados, who have an obvious, needed second type, the Normal/Flying Pokemon are mostly birds.

Except for some other Pokemon like Swablu, who really is a bird, but I think could be based a normal cloud, and Togetic and Togekiss, who might get it’s type from it’s prevolution Togepi - but otherwise, except for the Fairy-type, which it later got, what type could it have?

Also, Flying is a very obscure type. Like, a Rock-type could just be a Rock like Geodude, A plain Ghost-type would be a ghost like Misdreavus, a Dark-type could just be a Dark Pokemon like Umbreon, a plain Dragon-type would be a dragon like Dragonite - what would a Flying-type be? Something with wings? Say that to Gyarados or Tornadus.

So yeah, that’s pretty much the reason. Almost all Flying-types are birds, and therefore get that added Flying-type.

Hope I helped. :)

Only Game Freak knows.

The most logical reason would be that all the Flying Pokemon have some other similarity to another type. Look at Honchkrow; its design clearly implies Dark. Look at Moltres; its wings are on fire.

Another reason would be that most Flying type also have a dual Normal typing, like Braviary, Pidgeot, etc. Why this is we don’t know. Game Freak made the game, so they are the only ones that know.
