Hole in maple trees
I have two mature maple trees and birds are nesting inside the tree. We had large limbs removed and now the bark didn't grow back sealing the wound. Is this hurting or damaging the tree or is there something I should do?
If the birds are merely using holes that are already in the trees, that will not hurt the trees any further. If these are woodpeckers that are enlarging the holes, it could possibly weaken the structural integrity of the tree if the hole was huge. You could conceivably put hardware cloth over the hole to keep future nesting birds away.
Either way, the law protects all birds except a few pest birds like starlings and English sparrows. You cannot destroy nests of protected birds.
