Swellow is not capable of evolving into anything due to Swellow being a fully evolved Pokémon.
tailow evolves on level 22 to swellow which if people think he can evolve he cant so stop trying ya dingbats
A taillow can evolve into swellow but a swellow can't evolve.
I know Taillow evolves to Swellow but after that Swellow won't be able to evolve.Answer Swellow is one of the few Pokemon who only has one evoltion. (from Taillow to Swellow)
Swellow cant evolve

swellow doesn't evolve!
Ash's Pokémon in the Hoenn region are Pikachu, Taillow/Swellow, Treecko/Grovyle/Sceptile, Corphish, Torkoal, his original Bulbasaur that he left back home and Snorunt/Glalie.pikachu(obviously)toarkoalcorphishtreecko(which evolve into grovyle then sceptile)snorunt(which evovle into glalie)
Swellow cannot evolve, as it has already reached its final form.
I don't think swellow is capable of such a move.
Swellow,cuz swellow can learn more moves and better moves and has better stats than Tropius.
