Birdseye Maple is not technically a distinct species of Maple, but rather, it’s a figure that’s occasionally found in Acer saccharum (Sugar Maple) trees. It’s named “birdseye” (sometimes simply written out as: Bird’s Eye Maple) because the figure resembles small bird’s eyes. The figure is reportedly caused by unfavorable growing conditions for the tree. The Sugar Maple attempts to start numerous new buds to get more sunlight, but with poor growing conditions the new shoots are aborted, and afterward a number of tiny knots remain.
