This is a large vintage Thunderbird pendant which looks to be handcrafted by a silversmith or jewelry artisan. I believe this is aluminum or pewter, it is very light weight considering the size.
The Thunderbird's name comes from the common belief that the beating of its enormous wings causes thunder and stirs the wind. Depending on the people telling the story, the Thunderbird is either a singular entity or a species. In both cases, it is intelligent, powerful, and wrathful.
There are no markings on the pendant, again reflective of being handcrafted, possibly Native American Indian. Condition is Excellent -
