The Cincinnati Zoo is preparing for the arrival of a new giraffe calf as 19-year-old mother Tessa shows signs of impending labor. Staff and volunteers are maintaining round-the-clock watch to ensure the health of the calf sired by five-year-old Zeke.

Why it matters

The birth is part of a strategic effort supported by the Association of Zoos and Aquariums to grow the local giraffe herd. This addition will eventually support the zoo's broader expansion plans within their facility.

The zoo is offering a $20 entry fee for participants to enter a naming opportunity for the calf. Volunteers are currently supporting the effort by performing four-hour overnight monitoring shifts.
