Smeargle-Sketch
Sketcher of Smeargles
Unfezant line
Moves: Double Kick (Tranquill and Unfezant only), Close Combat (Unfezant only), Wing Attack, Peck, Nasty Plot (to help with the line learning mostly special moves), Play Rough, just any strong physical attacks. Smart Strike and Lash Out too because pheasants are aggressive.
Staraptor
Moves: Revenge, Lash Out, Smart Strike, and Payback because of its aggressive nature, since from the dex entry mentioned, it sounds like Staraptor will fight even to the point of it dying or being severely injured (this is very true with many raptor birds as they will fight to their deaths against other competing predators).
Zebstrika line
Moves: Rising Voltage, Thunder Cage, and Lash Out and Triple Axel
Swanna line
Moves: Calm Mind, Life Dew, Dual Wingbeat, Aqua Jet, Smart Strike, and Payback. Calm Mind because swans are seen as a peace symbol. Smart Strike and Payback and possibly Revenge because swans are known to be super aggressive and territorial and like the raptors on which Staraptor is based on will fight til death. Could also see Swanna in particular learning Esper Wing.
Toucannon
Moves: Dual Wingbeat and Bolt Beak. Bolt Beak well look at the size of its beak. Dual Wingbeat because well other Flying types learn it.
Swellow line
Moves: Dual Wingbeat, Esper Wing. If they don't learn it already Brave Bird.
Bolt Beak Toucannon is too good....
