Rare Dolphin Birth Captured on Camera at Chicago's Brookfield Zoo

Brookfield Zoo Welcomes New Dolphin Calf After Decade-Long Wait Chicago, IL – In a heartwarming event, Brookfield Zoo welcomed a new bottlenose dolphin calf into the world in the early hours of June 7th, 2025. The birth, the first at the zoo in more than ten years, was a significant moment for the zoo's marine mammal team. The mother dolphin, Allie, successfully delivered the calf after an hour and 22 minutes. The event was made even more special by the presence of Tapeko, a 43-year-old experienced mother dolphin who provided crucial support during the birthing process. "It was truly amazing to witness," said a zookeeper, who wishes to remain anonymous. "The cooperation between Allie and Tapeko was incredible." The calf, weighing between 15 and 17 kg and measuring between 115 and 120 cm, quickly surfaced for its first breath. The zoo's veterinary staff is closely monitoring both mother and calf, and early signs indicate a healthy start for the new arrival. This birth marks a significant step forward for the zoo's conservation efforts and provides a beacon of hope for the future of these magnificent creatures.
