I have seen this goose for the last week in the pond located at Centennial Park in Orland Park. Sometimes it is with a group but other times it is alone. Its left wing is dragging and doesn't fold into place like the right side. It is able to walk and does go into the water. Most times it is in the same location but once I did see at in another spot. If it isn't able to fly, what will happen in the winter? What can be done to help it?
