The longtime director of Henson Robinson Zoo has resigned.
Talon Thornton had run the zoo since 1995.
His resignation is open-ended, and he will stay on until a replacement is found. Thornton reportedly cited “personal reasons” for deciding to leave. He did not return calls seeking comment.
The zoo has been under a microscope in recent months.
Its bid for accreditation was put on hold last year pending improvements to its facilities and exhibits.
The park district also adopted a new master plan last year for upgrades at the zoo.
