I love that solution, but was too expensive for me. So I put plastic garden lattice over the windows and in front of the sliding glass doors to keep the birds from flying into them. Works great and allows me to hang toys, perches, platforms and foraging areas on the lattice as well. I did put a foraging area on my net, which a good friend was nice to donate to me. Most of the birds are still warming up to the net after two years!
PS: Using plastic lattice has not kept the birds from chewing on the lattice. Oscar RBP has removed the top four inches of one of the panels over the past year. He works on it daily... However, the plastic is easier to clean than the wood lattice, even when the wood is painted with baby safe paint.
