Field Trip

Leader: Gene Groshon

Visit this unique swampland where one of Southern Maryland’s most eye-popping warblers makes its home.  The Prothonotary Warbler will be in full song, setting up its breeding territories.  Our leader Gene Groshon has been banding Prothonotaries in this location for several years. Our goal will be to identify individual warblers that have just returned from Venezuela, Colombia, or Mexico to the Cypress Swamp to nest again. The Sanctuary includes a visitors’ center and a boardwalk through the swamp, so the birding should be excellent at the height of spring migration. DIRECTIONS:  About 2 mi south of Prince Frederick, MD on Rt 4, turn south on Sixes Road (Rt 506). In 2 miles turn left on Grays Road.  Proceed for about a quarter mile to Sanctuary entrance on the right.  Group size may be limited. Register online at:
