Photographed in April 2018. I was told that the Petrie Island mom owl is still slowly recovering (May 2018) but continues to exhibit neurological signs of brain injury such as head tilt, vision issues and balance/coordination symptoms They're going to give her 2 more months (end of July) to see how much she recovers.
