This is a great handmade Native American Thunderbird made of copper with a round green turquoise cabochon in the center. There is some nice stampings on this piece as well. I suppose one could use the ey of the bird to string something through to make a pendant. There are no markings on this piece. This came from a collection of Native American copper pieces I just acquired. The bird measures 1 1/8" by 1 1/8" and weighs 2.8 grams.
