Seagull and Pelicans Fish Battle

They are unrelated species that partially share a niche (seabirds). A seagull is a strong flying bird that also frequents the shore. A pelican is a swimming and diving bird with a deep bill that can scoop up fish from the surface.

Seagull is watching the pelican's every move. It is hoping that somewhere during the water removal/head-flipping process the pelican messes up and a fish gets away. If that happens it will swoop in and grab itself a meal, before the pelican recovers the lost goods.
