including 80 bird species as well as possums, raccoons, and skunks. Playgrounds Fort Tryon Park contains two playgrounds. The park's northeast corner contains the Anne Loftus Playground, a triangle-shaped play area that primarily serves the Inwood neighborhood to the north. It is named after Anne Susan Cahill Loftus, a local resident who was the district manager of Manhattan Community Board 12 between 1980 and 1989. Opened in 1934, the playground was the only section of Fort Tryon Park that was originally intended for "active recreation" and the only playground designed by the Olmsted Brothers. The Olmsted Brothers built the playground on the site because of its flatness and proximity to the streets nearby. The southwest side of the Anne Loftus Playground contains a one-story stone fieldhouse with a rooftop observation deck that is set into the cliff, and the northeast side contains an entrance to the Dyckman Street station. A large wading pool is located in the middle of the playground, and plane trees encircle the play area. The playground was restored in 1995-1997 under a $1.44 million project that also added handicapped-accessible facilities, additional play structures, and performance space. The other playground in Fort Tryon Park is the Jacob K. Javits Playground, which primarily serves Hudson Heights and is named after U.S. senator Jacob Javits. The play area contains a play structure and basketball courts, as well as elm trees throughout the playground. When the park was created, Empire Mortgage initially leased the playground to the city before giving away the land as a gift in 1944. The playground was transferred to NYC Parks in 1981 and renamed after Javits in 1984. It was renovated in 1995. After a second period of decline, another renovation of the playground started in 2019. Other features Margaret Corbin Circle is located at the intersection of Cabrini Boulevard and Fort Washington Avenue, on the park's southern border. Formerly known simply as the South Plaza, it was renamed in 1977 after Corbin. The plaza consists of a roundabout for traffic, and is surrounded by a low stone perimeter wall, with stone posts flanking the entrances to the building. A planted circle is located in the center of the roundabout. The old Fort Tryon Cottage (see ) and the station building to the New York City Subway's 190th Street station are located on the edges of the plaza. A bronze plaque commemorating Corbin is located
