In recent years, many more red-tailed hawks have taken up residence in New York City. 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. In 2014, there were eleven red-tailed nests reported in Manhattan, of which ten were known to have fledged baby hawks. Relatively small green spaces about the city, such as the main Columbia University campus, may see red-tailed hawk visitors, while slightly larger locations, such as Washington Square Park and the Fordham University Rose Hill campus, may have nesting pairs.
