Hi Martin
Sally Goulden is a licensed veterinarian and submitted her credentials. Because the research is specifically written for Licensed veterinarians, you would need to provide us with your appropriate credentials. If you are not a licensed veterinarian, you can contact Wendy Hermon, Swan Support or Steve Knight, Swan Sanctuary, to confirm that their veterinarians are in possession of our research. These two swan rescue groups are promoting the feeding of bread to swans. The Regal Swan Foundation
