Black-Crowned Night Herons Face Uncertain Future in New York City

Black-crowned night herons, well-known for their striking appearance and urban affinity, are facing a potential extinction threat in New York City. With muted colors and distinctive white plumes, these birds are a notable part of the city’s wildlife. Dustin Partridge, director of conservation and science at NYC Bird Alliance, describes them as quintessential New Yorkers. According to Partridge, “They are fashionable, they stay out late, and they love exploring new places.”

Standing approximately two feet tall, these birds have been sighted in various city locations such as Harlem’s green spaces, the East River in Queens, and Manhattan’s Lower East Side. Local residents have noted their interest in the city’s ecosystems, even jokingly claiming their fondness for rats.

Despite their popularity, black-crowned night herons face the risk of disappearing from New York City in the coming years. A study conducted by several organizations, including NYC Bird Alliance, formerly known as NYC Audubon, Cornell Lab of Ornithology, and Rutgers University, highlights this threat. The study warns that they could vanish completely in 11 years, similar to the fate of the passenger pigeon.

The exact reasons for the herons’ decline are uncertain. Possible contributing factors include water toxins, climate change effects, human disturbances, and predatory threats. There’s a broader issue at play, with an estimated loss of three billion birds across North America since 1970. Within the New York/New Jersey Harbor area, a 27 percent reduction in nesting wading birds has been documented from 2000 to 2022. This decline is largely attributed to a significant drop in the black-crowned night heron population.
