A dolphin named Allie gave birth early Saturday morning, zoo officials said.

The calf was the first bottlenose dolphin to be born at the zoo in ten years.

The zoo said the male calf appeared healthy until its abrupt death on Wednesday evening.

“While the calf was progressing well, dolphin neonates face immense biological challenges. We are deeply saddened by his sudden passing,” said Dr. Rita Stacey, Brookfield Zoo Chicago senior vice president of programs and impact.

Animal care teams witnessed a rapid, unexpected change in the calf’s behavior on Wednesday evening. Within minutes, the calf was unresponsive and passed away.
