That doesn't make it the generic bird. Could just be a random bird elsewhere in the Pokedex.
It's level 2. Generally starter birds and other elementary pokemon are under level 5 which is close to the hometown where the MC starts. Unless it is like black city/white forest, but the area is pretty grassy and no where special.
**** you SE for trolling us with that TWEWY port. I hate you.
We also saw a level 50 Hydreigon in the latest trailer despite that being impossible without hacking. Anything can be made up for screenshots and pre-release trailers.
Why would they go to the trouble of hacking in a level 2 Fletchling to fight a level 7 Chespin? Only reason Hydreigon was level 50 was because the Gardevoir was level 50, and 50 is exactly between 1 and 100. I don't know why they didn't make it 60, but whatever.

And he could still end up simply being more like Wingull. You can catch him just as early as Tailow, but Tailow the one people consider the starter bird.
Every starter bird has been Normal/Flying, which Fletchling is.
