Chatot evolutions

Chatot is one of my fave 4th gen pokemon, andi was dissapointed it had no evolutions... so i made some for it, these are what i believe they should look like.

1st Evolution: Budgeatter
Based on a budgie, since i love budgies... hey, if a remoraid (based on a fish) can evolve into an Octillery (An Octopus) then a Parrot can evolve into a budgie.

2nd Evolution: Tielatoir
Based on a Cockatiel (the sticking up "hair" feathers) and modelled after a composer, these would conduct flocks of Chatot and Budgeatter to sing a symphony.

How the evolution would work: Chatot would evolve when it knows three sound based attacks (I know that's allready possible, but then there's lickilicky). Budgeatter would evolve when a Chatot that knows sing is in the team.
