A rare group of marine predators gathered in the Perth Estuary in western Australia, as dolphins, pelicans and cormorants joined in a fishing frenzy.

The fishing party, filmed on August 3, 2009, was comprised mainly of Little Black cormorants, Australian pelicans and a pod of Indo-Pacific Bottlenose Dolphins (Tursiops aduncus).

The filmer commented: "At times the dolphins and pelicans seemed to cooperate, driving fish into the shallows. In their haste to catch a fish, two pelicans grabbed, then dropped a Little Black Cormorant from their beaks before realising their mistake and moving on.

"The fishing continued for over an hour and was watched by an enthralled crowd of people from the beach."

Perth, the capital of Western Australia, is the most isolated city in the world. The city surrounds the iconic Swan-Canning Estuary, Perth’s treasured waterway. The Estuary supports large numbers of waterbirds, including Australian Pelicans (Pelecanus conspicillatus), Little Black Cormorants (Phalacrocorax sulcirostris) and others. Sometimes several species of waterbirds combine to form fishing parties when a large school of fish appears, and a feeding frenzy occurs as the birds compete to catch a fish. On this occasion the fishing party was comprised mainly of Little Black Cormorants, Pelicans and a pod of Indo-Pacific Bottlenose Dolphins (Tursiops aduncus). At times the Dolphins and Pelicans seemed to cooperate , driving fish into the shallows. In their haste to catch a fish, two Pelicans grabbed, then dropped a Little Black Cormorant from their beaks before realising their mistake and moving on. The fishing continued for over an hour and was watched by an enthralled crowd of people from the beach.
