Members of this order are hatched on the ground, usually in a group of four, and are able to walk immediately after birth. These birds feed on insects, larvae, and small aquatic animals. These birds are identified by their long nasal groove, small, arched, and compressed claws, short legs, and webbed anterior toes. Gulls nest on the ground in rudely constructed nests and lay very few eggs. The young are born covered in down.
Gulls also have very large esophaguses.
Members of the procellarinae order are fulmas and albatrosses. These birds have bills that are shorter than their heads and a generally compact body. Their anterior toes are webbed, and they have four toes in general as well as claws. These birds have long wings and a tail with 12-16 feathers. In terms of their inner workings, procellarinae have very wide esophaguses and small stomachs.
