Two Falcons

I created these two sculptures are as falcons. They are a prairie falcon on top and a kestrel. They’re both American birds of prey.
Fossil walrus ivory exists on Alaska’s northern shores. It is also found near the shores in the ground and permafrost. Over the millennia minerals leached into the tusks. This resulting in the typical browns, butterscotch and ocher colors. Occasionally blue and green fossil walrus ivory is found. The color is caused by nearby copper or nickel.
