Vintage Pottery Bird

I thought the overall shape, details and quality looked like Royal Copley, but all of their birds are bright multi-colored. The solid color was used by Niloak on many animal figures and the quality is up to their standards. Frankly, I just don't know the manufacturer and would appreciate any input. It is 7 inches in height. There is no damage, but there are manufacturing flaws. Additional photographs are available by email. I need your zip code to calculate the postage.
