Not the best quality but I found two interesting things about this. It appears to be freeranging. Also the buildings in the background kinda look like aviaries?
Trouble with free-roam peacocks is their droppings (like geese) and the constant distressed-cat meowing. Had some in the small town I lived in near Yosemite a while back. Nice thing about a videogame, though, is the unpleasant bits can be left out.
