spawnMigrant
public PetControl spawnMigrant(PetSpecies pet, Location at, String model, double sizeMultiplier, int viewDistance, MigrationRoute route)
Puts a wild pet on a migration route: an ordinary wild pet of the species, wearing its full model, flying the route at the top of its Mind program. It is sizeMultiplier times the species' size, seen from viewDistance blocks and lit fully bright. A player who reaches it can tame it like any wild pet.
