POPULATION TREND: The king rail (Rallus elegans) has always been scarce in Pennsylvania. Confirmed breeding/nesting has been restricted to few locations in the state since the 1980s. A marshy field along Route 15 south of Lawrenceville in Tioga County, and State Game Lands 284 in Mercer County have been important breeding sites for this species. Until the early 1990s, one or two pairs nested in Philadelphia County’s Tinicum marshes, and nesting has been irregular at Crawford County’s Conneaut Marsh. It is possible this bird no longer occurs regularly at any single location in the state, but little is known of its habits in Pennsylvania. No confirmed breeding observations were reported during the 2nd Breeding Bird Atlas, 2004-2008, but there were more reports during this project than in recent years. Some reports suggest that there were active nesting pairs, but confirmation was lacking. A volunteerassisted marsh bird survey launched in 2013 may help to answer many questions. The king rail was designated a state endangered species in 1985 and remains endangered today.
