In December 2004, the hawks' nest and the anti-pigeon spikes that had long anchored it were removed by the board of the co-op. 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. Mary Tyler Moore, a resident of the building and animal rights advocate, also participated in the protests. On December 14, 2004, the building, various city agencies, and the Audubon Society came to an agreement to replace the spikes and to install a new "cradle" for the nest. By December 28, 2004, the scaffolding had been removed and the hawks started bringing twigs to the nest site.
