As all teenagers juvenile Pelicans sometimes act silly. The way of learning and maturing doesn't happen overnight. Thus Pelican on the photo above spotted something in the water thinking it was fish.
The pelican is going to pull his catch out of the water. His actions immediately attracted the attention of the gull-thief.
Everyone including the gull-thief is watching the silly Pelican who is pulling out of the water something slippery and long. This is a silt, silly...
What are you going to do with the silt? It's better to throw the silt away after all.
Generally, life is good!
