The 2,650-acre campus of the Smithsonian Environmental Research Center (SERC), situated on the Chesapeake Bay in Anne Arundel County, welcomes birders and other visitors to explore its varied habitats, which include forests, cropland, pastures, freshwater wetlands, tidal marshes, and estuaries, with 15 miles of protected shoreline. The SERC campus is located along the Rhode River, a sub-estuary of the Chesapeake Bay, in southern Anne Arundel County. A well-developed trail system takes you through most of the campus, but exploring the whole of this exceptional site will take more than one visit, given its size.

It is a privilege to have access to bird at SERC, which is the applied research arm of the nation’s venerable Smithsonian Institution. SERC’s research is centered on meeting the environmental challenges of the 21st century, with a specific focus on coastal ecosystems. The site serves as a natural laboratory for long-term and cutting-edge ecological research.

Upon arrival, please sign in at the Reed Education Center. There are three main trails to explore (see trail map at link at left; printed trail maps are available at the trailhead kiosk for the Contee Watershed Trail and at the Reed Education Center). The Contee Watershed Trail (1.6 miles, white blazes) traverses varying terrain through upland forest, cypress swamp, and marshland, and offers a scenic shoreline view of Sellman Creek. There are medium to difficult changes in elevation along the trail. It’s much easier to begin DOWNHILL through the steep field on the south loop of the trail. A second option is to take the Java History Trail (1.3 mile, blue blazes), starting from the Reed Education Center and passing through field, forest, and marsh. The Java History Trail is easy with little elevation change. The third option, the Discovery Trail (1.4 mile, pink blazes), passes through mature forests and over a long marsh boardwalk out to Hog Island. The Discovery Trail is another easy trail with minor elevation changes. The dock and launch area at the end of Dock Road is another good birding spot; you can check here for gulls, terns, and waterfowl in season.

Those who have their own canoes or kayaks can use the soft launch and SERC’s water trail map to closely explore the marshes and waterways.  SERC also offers public canoe days, when they supply canoes and guided tours (fee applies).

  • The SERC campus offers a rich environment to explore. In addition to its outstanding natural habitats, there are extensive historical features at the site, including formal archaeological excavations. See to explore the many cutting-edge environmental and historical research projects at SERC.
  • SERC offers a full calendar of  public tours, events, and programs, including science seminars.
  • There are numerous volunteer opportunities.
  • SERC is the only site within this Birder’s Guide to Maryland and DC with its own robot! Pepper is a humanoid robot that is friendly and fun. Pepper can pose for selfies, tell you about SERC programs, answer programmed questions, and even dance! The Smithsonian as a whole received 12 Pepper robots in February 2018 from SoftBank Robotics to be tested in museums, research centers, and educational spaces. SERC received two of those robots, which are continuously being programmed by staff and students to engage the public about environmental topics related to SERC research. One project involved students from nearby South River High School.
