Mumbai’s Byculla Zoo has turned what was once considered a controversial investment into a revenue-generating success. Civic data reveals that the Brihanmumbai Municipal Corporation (BMC) spent approximately ₹25.83 crore over five years on the upkeep of its Humboldt penguin enclosure — a figure that has sparked both scrutiny and surprise. Yet, over the same period, the zoo earned ₹40.39 crore from ticket sales, as more than one crore visitors walked through its gates, many drawn by the city’s only penguin colony.
The penguins — originally eight in number — were flown in from South Korea in 2016. Since then, their population has grown to 21, thanks to successful in-house breeding and sustained veterinary care. The initial criticism regarding the costs and ecological feasibility of housing cold-climate birds in a tropical city has slowly faded, with the data now painting a different picture — one of positive public engagement and financial returns. Officials overseeing the facility confirmed that the expenditure encompasses a range of operational needs, including climate control systems like industrial chillers, specialist veterinary staff salaries, maintenance of firefighting systems, water filtration units, temperature regulation equipment, and around-the-clock surveillance. The operational architecture is designed not just for spectacle but for sustaining a species not native to the Indian subcontinent in humane and scientifically monitored conditions.
The budget allocation for penguin upkeep, although sizeable, is proportionately modest when compared to other overheads incurred by the zoo. Over the same five-year span, the civic body spent ₹27.11 crore on housekeeping and ₹31.20 crore on garden maintenance. This brings the total expenditure on these auxiliary services to ₹58.31 crore — more than twice the amount used to care for the penguins. This contrast offers a nuanced view of resource distribution in one of the city’s most visited public spaces. The growing footfall has played a crucial role in offsetting costs. Experts argue that the penguin exhibit has rejuvenated interest in Mumbai’s only zoo, drawing visitors from neighbouring districts and even other states. In a metropolis where access to public green spaces and biodiversity is increasingly limited, Byculla Zoo stands as a rare intersection of conservation, education, and recreation. According to civic estimates, ticket sales since the arrival of the penguins have seen a consistent upward trend, contributing directly to zoo revenue and indirectly to the local economy.
Officials involved in zoo management described the penguin enclosure as more than an exhibit — instead, it is framed as an educational asset in an urban learning ecosystem. Interpretative boards, structured viewing zones, and guided awareness tours have been designed to foster a deeper understanding of species conservation among school children and general visitors alike. This aligns with broader urban sustainability goals that see biodiversity conservation not as a standalone mission, but as a core pillar of inclusive and eco-sensitive city planning. However, not all are fully convinced. Environmental critics still argue that replicating an Antarctic climate in Mumbai — a city with rising summer temperatures and water scarcity — demands high energy inputs, potentially counteracting sustainability objectives. Concerns have also been raised regarding the long-term ecological footprint of such exhibits in the face of global climate volatility and urban emissions.
Officials, in response, claim that several operational systems have been optimised over time to reduce energy consumption, including upgrades to chillers and filtration units. A long-term plan to integrate renewable energy into enclosure maintenance is reportedly under consideration. Engineers are also exploring green-certified technologies to make the facility more climate-resilient and cost-effective, thus aligning with India’s urban sustainability commitments under the SDGs (Sustainable Development Goals). Urban planners see the zoo’s penguin enclosure as a test case for balancing ecological aspirations with financial viability. “It’s rare for a public asset to attract such high visitor traffic while covering its own costs,” said a senior official associated with the urban biodiversity cell. “What we now need is a city-wide framework that encourages such initiatives while ensuring transparency, ethical care standards, and green design.”
Moreover, the penguin project has also opened up conversations about animal welfare laws and international trade regulations, particularly around the import of exotic species. Civic administrators have reiterated that the acquisition and care of the penguins adhered strictly to international norms laid down by CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). The successful breeding of the penguins within the zoo premises has also been celebrated as a milestone in captive care and species propagation. Veterinary staff and biologists involved in the initiative claim that the birth of new penguins under controlled conditions is a strong indicator that animal welfare protocols are being effectively implemented.
The debate on whether Mumbai needed penguins may never be fully settled, but the numbers now offer a compelling counterpoint. In a city where civic infrastructure often struggles under competing demands, a zoo’s ability to manage exotic species ethically, turn public engagement into sustainable revenue, and still spark debate about ecological responsibility, is noteworthy. For now, the penguins remain not just a popular attraction but a symbol of how cities might reimagine the place of animals within urban life — not merely as entertainment, but as co-inhabitants of an increasingly shared, constrained and climate-challenged world.
