Grass greener on the other side?

Psychology Professor Judy Nichols, Ph.D., captured this picture of a “white goose” among the Canadian geese in the park across from the zoo. Did this goose escape the zoo because it thought the grass was greener on the other side or is it trying to find its way to our bird banding station?! If someone knows what type of goose this is, submit the information via LincIn or stop by the PRM office and let us know.
