The incident occurred around 9 a.m. Zookeepers brought another giraffe to a separate area for a medical checkup. Wesley wanted to see what was going on, so he rested his head over the fence between two poles.
"Curiosity brought him back," Ron Magill, communications director for Zoo Miami told The Dodo.
Had he lifted his head the way he placed it there, he would have been fine. Instead, he pulled back and felt his head caught between the poles. Frightened, his legs buckled from underneath him. That's when the spinal cord injury occurred, according to Magill.
The team was immediately able to remove Wesley from the poles, but the damage had been done. After hours of attempting to save his life, the zoo made the difficult decision to relieve the calf of his pain.
