Some are sandy and populated by tall grasses such as the little blue stem. At first glance these areas appear devoid of wildlife but a close look between the grass dumps reveals a small world filled with living things. There is little cover in either type of field and animals here are careful to protect themselves from predators. Some burrow underground, like field mice or earthworms. Some use protective coloration, or camouflage.
Birds are very well suited to life here because they can fly quickly to safety.
You may encounter robins, pheasants, and killdeer in these open areas. Crickets and harmless garter snakes hide beneath old logs or other cover during the day and become active in the evening. Take some time to explore a field. The upland areas of Fort Tilden are good examples of a young coastal woodland. No longer directly exposed to the drying effects of wind and salt, a greater diversity of plant life grows in this area.
