Brookfield Zoo's Allie The Dolphin Is Celebrating Pregnancy!

Brookfield Zoo's Allie The Dolphin Is Celebrating Pregnancy! Staff at Brookfield Zoo in Chicago are delighted that Allie, their 37-year-old bottlenose dolphin is pregnant. With her pregnancy now in its second trimester, Allie’s journey is being carefully monitored by the Zoo’s expert animal care and veterinary teams. Dolphin pregnancies, which span approximately 12 months and are divided into four-month trimesters, differ significantly from human gestation. Through the trusting bonds and relationship built between her and the Zoo team, Allie willingly participates in ultrasound examinations and blood tests. Staff are expecting to see changes in her behaviors that indicate imminent labour as early as May. Allie’s pregnancy isn’t just a moment of joy for her but provides a critical opportunity to study prenatal and neonatal dolphin care as the first year of life for a dolphin calf, both in the wild and under professional human care, is filled with challenges and milestones it must reach.
