I have taken an XMLSpawner and set it's itemid to that of a Parrot Perch. Set it to visible true. Set Spawn Range and Home Range to 0. Cantwalk to true for the parrot.
Now it there a way to cause the spawn to be the spawners z + 6 so the parrot spawns on top of the art.
I am able to add a parrot perch and set the spawner on top of it and that works. But to staff it is not visualy appealing. The spawner is almost as big as the parrot.
(parrots name)/z/#
Like for example its probably 10, I used this to spawn a ghost above an NPC's head in one of my quests =P
