I can't remember, but I think it has to be level 22.
well im not sure but my tailow is level 15 and it still not being able to evolve
tailow evolves on level 22 to swellow which if people think he can evolve he cant so stop trying ya dingbats
Level 22.
Go to Google and type in the Pokemon you want to know about. You'll get a boat load of information-- I reccommend Bulbapedia. FYI-- Swellow does not evolve. If you meant Tailow evolving to Swellow, the level's 22.
Imran: Tailow evolves at Level 22 into Swellow in Pokemon Ruby.A Swellow should always know Wing Attack and Steel Wing which is very helpful for the Pokemon League if your Swellow is over Level 50.
Taillow evolves into Swellow at level 22 and does not evolve further. Swellow should always know Fly and Steel Wing.
Tauros does not have any evolutions and will not evolve at any level in Pokemon Soul Silver.
Evolve it from larvitar at level 30 to evolve it into pupitar then evolve it into tyranitar at level 55
Tailow evolves to Swellow at level 22 I think that it does evolve at level 22 But if you have Pokemon Diamond Then get the Poke radar and head to Pastoria City and use it and get a Swellow at level 20 - 23 The 7th gym leader is at Cinnabar Island. Go to Pallet Town and surf south to reach Cinnabar. It's a fire type gym leader so be careful.
