hawks. That nest site was active until 2016. Reports of further attempts to nest on buildings along or near Central Park South since 2016 have continued, e.g., at the Ritz-Carlton in 2022, but none have been reported successful. A pair of red-tails known for several years of unsuccessful nesting attempts on buildings along Central Park West built a nest in Central Park's Pinetum in 2022 and successfully fledged two babies. A hawk couple known as Tristan and Isolde claimed Central Park's Great Hill and North Wood as their territory in 2006, but their nest was located about four blocks from the park at the Cathedral of St. John the Divine, overlooking Morningside Park. Although both Tristan and Isolde have since died or disappeared, they and their successors at the cathedral nest had fledged 28 baby red-tails as of 2020. Attempted red-tail nesting activity has been reported at other locations on the periphery of Central Park, including locations on Central Park West since 2013, but none were successful until 2021. In 2021 and 2022, a pair of red-tailed hawks nested on the Terence Cardinal Cooke Health Center, across Fifth Avenue from Central Park's Conservatory Garden, and hatches were reported there. A 2007 study commissioned by the Audubon Society reported that pairs of red-tails were spotted breeding in nests at 32 locations throughout the city, and hawk watchers say they have spotted dozens of unattached red-tails across the five boroughs. Since 2010, there have been typically been about ten active red-tailed hawk nests in Manhattan per year. For example, in 2014, there were at least eleven red-tailed nests reported in Manhattan, of which ten were known to have fledged baby hawks. In 2021 there were ten nests reported, but only five were confirmed to fledge at least a young bird. Relatively small green spaces about the city may see red-tailed hawk visitors, while slightly larger locations, such as Washington Square Park, Tompkins Square Park, the Fordham University Rose Hill campus, and the main Columbia University campus, may support nesting pairs. In popular culture Pale Male, a one-hour documentary by filmmaker Frederic Lilien, aired on WNET's Nature in 2004. A feature documentary called The Legend of Pale Male by Frederic Lilien was completed in April 2009. Alternative country singer Steve Earle references Pale Male in his song "Down Here Below", from the 2007 album Washington Square Serenade. A puppet of Pale Male made
