Mexico City Zoo Cools Off Bears With Frozen Fruit Popsicles Amid Heatwave

Jerry, a Spectacled Bear at Mexico City’s Chapultepec Zoo, recently enjoyed a frozen fruit popsicle during a scorching heatwave. The zoo has long used creative methods to help animals cope with rising temperatures, including special treats and cooling measures. The popsicle given to Jerry was made from apple juice, mango, grapes, carrots, and water. Veterinarians and nutritionists design these treats to match each species’ dietary needs. Beyond frozen snacks, the zoo provides shaded areas, cool dormitories, and different ground materials to keep animals comfortable.

Animals with thick fur, such as bears and big cats, receive extra care during extreme heat. Zoo staff also use ethograms—detailed behaviour logs—to observe how creatures respond to enrichment activities like popsicles. Alberto Olascoaga, the zoo’s director, has overseen these practices for more than 20 years. Climate change is shifting the natural cycles of some species at Chapultepec. As temperatures climb, the zoo continues adapting its strategies to protect wildlife from heat stress.

The frozen treats and cooling measures help animals like Jerry stay safe during heatwaves. With climate patterns changing, the zoo’s long-standing methods remain vital for animal welfare. Staff monitor responses closely to ensure each species thrives in warmer conditions.
