The male swan isn't around right now. After awhile, I see him way off by the gazebo by the gingkos—looking for a handout no doubt, of stale bread from people who don't know any better than to feed bread to birds, ducks, geese and swans. Some birds can develop a condition known as Angel wing which is the result of improper nutrition. Bread can cause vitamin and mineral deficiencies that contribute to this developmental disorder.
These Prospect Park Swans have plenty of aquatic vegetation and insects, even tiny fish and tadpoles to eat.
