J.N. "Ding" Darling National Wildlife Refuge is located on the Sanibel Island in Southwestern Florida. It is part of the US National Wildlife Refuge System with 230 species of birds, most of them migratory. It contains one of the country's largest mangrove ecosystems with 2. 619 protected acres. Jon and Phyllis spent 5 days photographing these marvelous birds and are sharing them with the rest of us. I feel privileged to put them on my website!
