 In 1946, the last pair of bald eagles on the Anacostia River abandoned their nest on Kingman Island.Although a bird watcher claimed to have seen a bald eagle nest on the Anacostia River in 1988, the bald eagle did not return until transplanted eaglets returned to the river as adults in 2004.The city finally extended East Capitol Street across the Anacostia River and Kingman Island in 1955.
