Icy water reflects the sunset at Edwin B. Forsythe National Wildlife Refuge in New Jersey. More than 80 percent of the refuge’s 47,000 acres is wetlands. The quiet tidal waters serve as nurseries, spawning and feeding grounds for fish and shellfish, which are important in the diets of many wildlife species – particularly the migratory birds who live and visit here.
