Alipore Zoo in Kolkata is taking proactive measures to protect its animal residents as a severe heatwave affects several districts of South Bengal, with temperatures rising to 40°C. The zoo has put in place a variety of cooling systems and dietary changes to help the animals cope with the extreme temperatures. These efforts are part of the zoo's commitment to animal welfare during this intense summer heat.
To alleviate the heat, coolers have been installed in the enclosures of species like bears and kangaroos, which are particularly vulnerable to high temperatures. Tigers and lions, known for their larger body mass, are being provided with fans to generate a breeze, encouraging them to stay cool by resting in their enclosures. For the chimpanzees, special cooling foods like yogurt and lassi are being given, offering both hydration and relief from the heat. Water is also being sprayed through sprinklers in the enclosures of birds and snakes to help maintain a cooler environment.
The zoo has also adjusted the diets of its animals to ensure they remain comfortable and hydrated. The meat intake of tigers and lions has been reduced from 11 kg during the winter to 8 kg to avoid heat stress. Additionally, the zoo has provided these big cats with Oral Rehydration Solution (ORS) and anti-stress medications to help them adapt to the high temperatures. Birds, which are more susceptible to heat-related illnesses, are being cared for by covering their cages with sphagnum moss, and zoo workers are spraying water on them twice a day to keep them hydrated and cool.
Dietary changes have been made for other animals as well. Chimpanzees are being given more cucumbers and watermelons, while their morning meals now include fruit juice, yogurt, and lassi for hydration. The zoo is also providing rice with yogurt for its bears, a cooling and easily digestible meal. To further combat the heat, coolers and ice blocks have been placed in the enclosures of Himalayan bears to maintain a comfortable temperature. Many of the zoo’s large animals, such as tigers, elephants, leopards, and chimpanzees, are also taking daily baths to help them stay cool.
While the heat has led to a decrease in visitor numbers during the summer months, those who do visit the zoo find that some animals, such as Snehashis and Rupara, are less active. After their morning baths, these animals prefer to retreat to their enclosures and stay indoors, enjoying the cool breeze from fans. Alipore Zoo Director Arun Mukherjee emphasized that the zoo’s staff closely monitors the animals' well-being during these extreme temperatures, adjusting their care routines to ensure their health and comfort.
