On land, snakes, owls and hawks are potential predators, along with introduced mammals such as cats and rats. On inland streams and dams they turn to their most favored meals: yabbies (freshwater crayfish). When the bird captures and tries to swallow a large fish, the fish is caught in the bird's throat.

Two distinct genera of prehistoric cormorants are widely accepted today, if Phalacrocorax is used for all living species: The proposed genus Oligocorax appears to be paraphyletic the European species have been separated in Nectornis, and the North American ones are placed in the expanded Phalacrocorax. Atlantic coast and through the Mississippi and Missouri Valleys to the Gulf There is usually one brood a year. Several evolutionary groups are still recognizable. After feeding, cormorants characteristically dry their feathers by perching with their wings outstretched. pursuit of fish. It was estimated that by minimum 15.4% of tagged adult sea trout were predated by cormorants.

[26] The resolution provided by the mtDNA 12S rRNA and ATPase subunits six and eight sequence data[26] is not sufficient to properly resolve several groups to satisfaction; in addition, many species remain unsampled, the fossil record has not been integrated in the data, and the effects of hybridisation known in some Pacific species especially on the DNA sequence data are unstudied. In April, the pair begins construction of an elevated Cormorants are pellet-makers, creating pellets out of the bones and scales of the fish they eat, then spitting them out, just like some owls. Its toes are what is called totipalmate, meaning fully webbed gizzard shad (Dorosoma However, exceptions have been documented Many species also hunt together.
