The drama escalated when Luna, possibly lonely, began mimicking Tia’s movements to attract Jake. A bloody fight broke out between Tia and Luna—two females who had lived peacefully for a decade. The zoo had to physically separate Luna into a different barn. The keepers described it in staff notes as "an elephantine soap opera." The moral? Even seven-ton mammals get jealous.

She did not run—giraffes do not run for others. But she walked with purpose. She stood at the fence, craned her neck over the top rail (which keepers had insisted was too high for a giraffe to reach), and let out a low, vibrating hum. Giraffes hum at night, sometimes. Rarely during the day. But she hummed for him.

By providing naturalistic habitats and introducing compatible animals to each other, these organizations are helping to ensure the long-term survival of endangered species.
