As requested:
I looked up the references that you gave for laws by state on your Coturnix education post. Thought you might want to update the info for Arizona. Here is a summary of the pertinent law (R12-4-419. Game Bird Hobby License):
The Department shall only issue a license for the following game bird species:
a. Blue grouse, Dendragapus obscurus;
b. California or valley quail, Callipepla californica;
c. Chukar, Alectoris chukar;
d. Gambel's quail, Callipepla gambelii;
e. Montezuma or Mearns' quail, Cyrtonyx montezumae;
f. Northern bobwhite, Colinus virginianus, which only requires a game bird hobby license if used in game management units 34A, 36A, 36B, and 36C;
g. Ringneck and whitewing pheasant, Phasianus colchicus;
h. Scaled quail, Callipepla squamata;
Japanese Quail and Chinese Painted Quail are not listed. Also, you can buy both of these quail at local pet store/feed stores.
