This lifeform is found widely in the Atlantic Ocean. The brown color will help identify this lifeform. This lifeform is rare.

Great Ski (Cataract ski) is found in the colder regions near both the north and south pole. The southern populations breed in Antarctica, Chile, and even New Zealand. The northern populations nest in Iceland, the Orkney Islands, and other northern places. In winter, members of the northern populations can be seen in Newfoundland and New England.  

Seemingly, the two polar populations do not intermingle. Two subspecies may perhaps be involved. This bulky brown bird is typically about twenty-three inches in length.

The Skua frequently chases other smaller gulls and terns to force them to drop their food and in this way frequently avoids the work of foraging for its own food. In the southern hemisphere, the Skuas also feed on Penguin eggs.

Jaegers and Skuas (Family Stercorariidae) are frequently  combined with the gulls and terns in to a single larger family.  In fact, the four species in this family are very similar to the gulls. Only some differences in the nostrils set this group  apart.

Shorebirds (Order Charadriformes) are a group of 305 species of
worldwide birds. While good fliers, they are much observed feeding along seashores and in the vicinity of inland bodies of water. Seagulls and Sandpipers are typical representatives of this order

Aves contains about 8,650 different species of living birds known to science. Each year about one new species is discovered in some remote rain forest or remote island. In addition, scientists have been raising many subspecies to full species status which may raise the species count to 10,000.

However, each year about one species goes extinct. The rate of extinction is increasing, and the rate of new discovery is decreasing, so that the number of bird species will soon begin to decline rapidly. Although different taxonomists would organize the birds differently, there are approximately twenty-seven orders of birds. These orders are broken down into about one hundred and fifty-five different families.

Recent research of the genetic structure of some of the shore birds and owls would indicate that the present organization of orders and families should have some modification.

The birds are a worldwide group of animals that are characterized by having the front limbs modified into wings that are used for flying. Perhaps the most unique feature of the birds is the feathers. These feathers are made up of a central support called a quill and a series of small filaments that are hooked together as barbs.

For many years it was believed that Archaeopteryx discovered in Bavaria was the oldest bird from about 150 million years ago.  However, in l986, Sankar Chattterjee, a Texas paleontologist, reportedly discovered a bird in the genus Protoavis that lived about 225 million years ago.

Backboned Animals (Phylum Chordata) are the most advanced group of animals on earth. These animals are characterized by having a spinal cord or backbone. Most members have a clearly defined brain that controls the organism through a spinal cord. Fish, amphibians, reptiles, birds, and mammals are in this phylum.

Currently, some taxonomists believe that the fish should be divided into two groups (sharks and regular fishes) and that there are some other primitive groups in the phylum such as hagfish or lampreys.

Animal Kingdom contains numerous organisms that feed on other animals or plants. Included in the animal kingdom are the lower marine invertebrates such as sponges and corals, the jointed legged animals such as insects and spiders, and the backboned animals such as fish, amphibians, reptiles, birds, and mammals.
