New York City is one of the most light-polluted cities in the world, with an average sky brightness of 32 times the natural level, which affects millions of birds that pass through the city during their migration seasons. Artificial light pollution not only has a negative effect on humans but also many wildlife species, especially birds. Birds rely on natural light cues for their migration, navigation, communication, and reproduction. Artificial light pollution can disrupt these behaviors and cause negative consequences for their survival and well-being.

Introduced in the NY State Senate by State Senator Brad Hoylman-Sigal (District 47) and the NY State Assembly by State Assemblymember Dr. Anna R. Kelles (District 125), the FLACO Act would amend the public buildings law to incorporate the use of bird-safe features, practices, and strategies to reduce bird fatality resulting from collisions with state-owned or state-leased buildings. 

In recent years, as the need to protect the City has become ever more imperative in the face of climate change, city planners have begun to design built infrastructure to mimic the ecosystem services provided by natural areas. 

Drone shows—spectacles of artificial light, often held in otherwise previously dark skies—can be detrimental to birds if not timed or sited correctly. NYC Audubon is working to better understand the effects of these new public art displays and limit their threat to the City’s wild birds.

Horseshoe Crab eggs are a critical food supply for migrating shorebirds, like the Red Knot. Although horseshoe crab eggs may seem abundant, declines in horseshoe crab populations due to over-harvesting are believed to be connected to declines in the migrating shorebird populations.
