>>38100824Charizard, Gyarados, and Dragonite all make sense being wind, everything else should be Bird.
Wind implies some mastery over the air or ability to manipulate it, while Bird just means it has wings and flies.
Even Charizard is debatable, I just threw it in because only having two gen 1 Wind types seemed sad. Gyarados obviously isn't a bird, and while Dragonite has wings, it clearly can't keep itself aloft with them, and has associations with causing storms.
None of the others do anything vaguely "wind" related besides fly in it.

Sedimentary rocks are usually Ground, or Rock/Ground, Igneous rocks are usually pure Rock or Rock/Fire, and Metamorphic is either Rock/Steel or Ground/Steel
