Places We Protect

Frank M. Ewing / Robinson Neck Preserve

Maryland / DC

A birder's delight of undisturbed waterfowl habitat and a sanctuary for bald eagles.

Established in 1977 by a generous donation from Frank M. Ewing, Robinson Neck is a birder's delight.  Keep an eye out for bald eagles, osprey, and marsh hawks. May is the best time for birdwatching, when migration is at a peak; summer brings a proliferation of flowering plants and marsh grasses; fall brings migrating birds, highlighted by warblers and puddle ducks.

This mature forest also provides ideal habitat for the federally endangered Delmarva fox squirrel (Sciurus niger cinereus).  Fox squirrels are larger and have bushier tails than common gray squirrels.  Don't be disappointed if you don't see one; they are much more elusive than our common friends.

The brackish marshes of Robinson Neck Preserve are of extraordinary ecological value for wintering and nesting waterfowl, spawning fish, sediment control, and nutrient production. 

Many such brackish bay marshes have been drained or filled for farmland and development.  Nearby upland forests provide an important buffer in the protection of these marshes and the entire Chesapeake Bay.

By protecting these habitats, we can help sustain the natural systems that are the lifeblood of the Chesapeake Bay.
