Home to over 11,000 animals across 265 acres, the Bronx Zoo is the largest metropolitan zoo in the world. But beyond its impressive scale lies a remarkable story, one of vision, innovation, and a deep commitment to wildlife.
Join us as we journey through time to uncover the rich history that shaped the Bronx Zoo into a global leader in conservation and education.
The Bronx Zoo originated from the conservation movement of the late 19th century. In 1895, the New York Zoological Society, now known as the Wildlife Conservation Society (WCS), was established to promote zoological research, public education, and wildlife preservation.
The zoo officially opened in 1899, showcasing 843 animals across 22 exhibits. Early on, it pioneered naturalistic enclosures that mimicked animals’ native habitats.
With support from President Theodore Roosevelt, the zoo bred bison and successfully reintroduced them into protected areas in the western United States.
During the mid-20th century, the Bronx Zoo became a center for scientific research and breeding endangered species. It gained international recognition for its work with species such as the Arabian oryx, snow leopard, and Indian gharial.
The zoo evolved from merely being a display facility into a hub for field research and wildlife advocacy. In 1972, the parent organization launched Wildlife Conservation International, marking a formal commitment to protecting wildlife habitats worldwide.
From the 1980s onward, the Bronx Zoo transformed exhibit design and environmental education. In 1999, it opened the Congo Gorilla Forest, an immersive rainforest habitat that combined lush environments with interactive elements and supported conservation efforts in Central Africa.
Inspired by this success, the Madagascar! exhibit debuted in 2003, showcasing the island’s unique and endangered species. By the 2010s, the zoo adopted sustainability initiatives such as solar power, composting, and eco-friendly landscaping.
The Bronx Zoo and its partners began the reintroduction of the critically endangered blue iguana to its native habitat on Grand Cayman Island. By 2018, the program had released its 1,000th blue iguana.
Celebrating its 120th anniversary in 2019, the Bronx Zoo stood as a symbol of conservation progress. The COVID-19 pandemic in 2020 posed significant challenges, prompting the zoo to innovate with Virtual Wild Encounters and educational livestreams to engage audiences remotely. These digital programs expanded the zoo’s reach worldwide despite physical closures.
