Bird Stones & Bird Effigies.
These stones are somewhat puzzling, not as to what they are, but rather as to why there are so many, and why there was so much time spent in making some of these. They obviously played a very important part in the culture or religion of the time since so much valuable time was spent on collecting and making them. Some of these had to take an incredible amount of time to make. Birds must have been an important part of their culture. Of the effigies I have collected so far, birds outnumber the other animals nearly 10 to 1.
