New York City Audubon said Wednesday that the red-tailed hawks' eggs haven't hatched, and the incubation period has passed.
Nonetheless, city Parks Commissioner Adrian Benepe says the activities of the avian pair - known as Pale Male and Lola - "will continue to convert urbane New Yorkers into nature lovers."
The duo produced seven chicks between 2002 and 2004, when residents of the East 74th Street building had the 12th-floor nest removed. They said the hawks were creating a health hazard.
The nest was restored after an uproar from birders and wildlife officials.
