Pelecaniformes are distinguished from other birds. They have webbed feet, a bare throat patch, and they breathe through their mouths because they have dysfunctional slits. Pelecaniformes birds can be located worldwide, primarily in coastal and marine zones. These birds inhabit marine and island waters. Pelecaniformes mostly feed on fish and squid. Also, this bird has been known to prey on mollusks and crustaceans. Some of their predators would include humans, birds, rats, cats, dogs, and reptiles.

There are about one- third of Pelecaniformes birds that may have come close to extinction. These problems include polluted water and loss of habitat for nesting.  Their nesting is colonial. Some nesting site can be found anywhere from in a tree or bush or on a cliff. However there are many Pelecaniformes birds still living today.
