The petroglyph shows an image that experts say represents a hummingbird, a very important symbol for Costa Rica’s indigenous peoples. The bird was a symbol of fertility among local indigenous groups, they said.
The rock also has two compound parallel spirals, placed in opposite directions. Experts say they represent the river flows and their relationship with burial sites located along the Blanco River.
