NYC Bird Alliance (formerly New York City Audubon) is an American non-profit environmental organization incorporated in 1979.
In recent years, it has exercised particular influence in two areas: the restoration of the red-tailed hawk Pale Male's nest and the fatal effects of light pollution and glass windows on migratory birds.
[4][5] NYC Bird Alliance organized the protests that followed the removal of the hawk Pale Male’s nest in December 2004 and played a major role in negotiating a solution with the co-op board of 927 Fifth Avenue.
In 2008, it recruited experts from around the country to assess the problem, and removed pigeon spikes from the nest structure as a result of their recommendations.
Dr. Daniel Klem of Muhlenberg College, an international authority on the bird collision topic, is leading[needs update] the study.
[9][10] Unknown to most, even to many birdwatchers, the small islands of the highly commercialized and heavily developed New York/New Jersey Estuary are home to one of the Atlantic Coast's largest colonies of nesting herons – with more than 3,000 individuals.
