Of course, when we're not sure what kind of bird is in a component or picture, we automatically assume it to be a crow. That's what we did with this bone component. It has been hand-finished and decorated with petroglyph or cave drawing of a bird and its tracks.
Each of these is slightly different as natural materials such as bone feature variation as a part of their charm. Each measures approximately 35mm wide (just less than 1-1/2 inch). The image of the bird and its tracks is carved into the bone piece an then darkened for emphasis.
