I regularly place seeds on my deck railing to feed the birds (and the squirrels). They knock some of the seeds to the deck floor.
Some birds go for the seeds on the deck floor. Those birds frequently fly between the balusters, both when coming and going. The balusters are 1.5" across, with 5" gaps between them.
Based on watching those birds, I would not have expected a "zen curtain" to help. I'd expect birds to think they could simply fly through the gaps.
