EVANSVILLE, IN (WFIE) - Happy birthday, Berta! Mesker Park Zoo & Botanic Garden celebrated the grey gibbon's 52nd birthday on Wednesday.
Zookeepers made a cornbread cake with fruit, yogurt and coconut, and gift bags to promote foraging, which is natural behavior for gibbons.
According to zoo officials, Berta has outlived the average 25-year lifespan of a grey gibbon in the wild. Berta is also one of the oldest grey gibbons in AZA-accredited zoos.
Mesker Park Zoo & Botanic Garden is open from 9:00 a.m. to 4:00 p.m. every day.
