Each spring, bird watchers would set up telescopes alongside Central Park's Model Boat Pond to observe his nest and chicks at 927 Fifth Avenue.

Although it was suggested over the years that Pale Male could have died and been replaced by a similarly colored bird without the change being observed, there was no strong evidence to confirm or deny this possibility.

[2] When he arrived in Central Park in 1991, as a first-year immature hawk, Pale Male tried to nest in a tree, but he was driven off by crows.

They raised seven eyasses between 2002 and 2004, building a nest on ornamental stonework above a top-story window on a residential housing cooperative at 927 Fifth Avenue, near 74th Street on the Upper East Side of Manhattan.

Ginger exhibited behavior consistent with incubation of eggs in mid-April 2011 and two eyasses emerged towards the end of May 2011, producing the first baby hawks in this nest since 2004.

Blood work and X-ray scans were done and Horvath then took him to WINORR to provide supportive care while they waited for the test results.

[16][17] The removal caused an international outcry and a series of impassioned protests organized by New York City Audubon Society and the Central Park birding community.

[18] By December 12, 2004, the building, various city agencies, and the Audubon Society agreed to seek a solution,[19] and quickly came to an agreement to replace the spikes and to install a new "cradle" for the nest.

[23] Since 2000, other adult hawk pairs have nested in or on the bounds of Central Park, with varying degrees of success.

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.

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.

[31] Relatively small green spaces about the city may see red-tailed hawk visitors, while slightly larger locations, such as Washington Square Park,[32] Tompkins Square Park,[33] the Fordham University Rose Hill campus,[34] and the main Columbia University campus, may support nesting pairs.
