I just checked again the September/October Bird Watcher’s Digest article on bird friendly wine and the article suggests going to the National Audubon’s website (audubon.org/news/its-past-time-bird-friendly-wine) for more information. Another website the author of the article suggested for more information is lodigrowers.com/certification. 
Have a glass of wine for me if you pursue Bird Friendly Wine 🍷.
