I think it learns it on level 9
This happens at Level 16.
Most likely an enemy used a pokemon switching move. That or your game is glitching. Does it switch it with another pokemon? Does the enemy use a move like whirlwind or gust? If you answer these questions on my message board I can help more.

Pidgey's moves are gust, sand attack and quick attack. As the level grows and it evolves, it can learn more stronger moves. Pidgey can learn fly even if it's not evolved yet.
Hoothoot cannot learn gust.
Well if you take a squartile (or that's how you spell it) your rival will take bulbasaur and if you take a pidgey and teach it wing attack and gust and deafiting kene is easy. Deafting brock is easy if you have a squartile or a bulbusaur. I suggest you go with squartile.
Altaria

It can't learn much but, it can learn sweet scent, and gust. That's all I can get mine to learn and it's level 83.
Gust Peck Cutting Wind Fly Double Edge

Choose your attack like gust.
Gust hit with x2 damage.
No, because gust is a flying type attack which isn't effective against rock type Pokémon. I recommend grass, water or ground type moves.
