Bird's eye Maple is a domestic hardwood. The Bird's eye figure is found in heartwood and sapwood. Both can be breathtaking. The boards are from Maple logs with irregular growth. The figure resembles the figure in a burl. It contains a small "eye" like in a burl, but it is more distinct. Each eye stands out separately. Small circular or elliptical areas resembling bird’s eyes on the tangential surface of the wood, formed by indented fibers. Bird's eye figure is caused by a stunted growth, developed during the years the tree lacked space and sunshine.
