Thanks for the input, the piece was ripped out on one side if I was to glue it back it wouldn't look right, I can cut out the piece that's still on the picture so you don't notice it.
I cut a stack of 2 owls and on one cut the broad jumped and the piece broke off from the tree in the upper right side on one of the broads but nothing happened to the owl, I really don't want to waste the owl, do you think it's savable ?
