Deer, Birds, and Patio Doors - To Grid or Not to Grid




BUT
We're putting on addition that will have 12' of patio door across the south end of the living room - two doors that open and one on either side that is fixed. See photos below of samples.
WHAT TO DO.
Do you think we need to get patio doors with the built-in grid to keep the deer and birds from thinking it's a wide open space and crashing through (or into) them?
OR is there a way we can keep the view (no grid) and yet protect the deer and birds? I would much prefer to have no grid, but need some good ideas - please?
