This spoonbill is getting ready to take off. The pale pink color of its feathers and the white feathers on top of its head indicate this is a juvenile bird. An adult would have more deeply colored feathers and a bald head.
In the evening, Spoonbills, Ibis, and other birds gather in this shallow area of water along the wildlife drive. This is a safe place for them to spend the night. Here is a Spoonbill coming in for a landing.
