This lifeform is found in the Yukon Providence or Alaska in North America. This lifeform is found in Argentina and Chile. This lifeform has become extinct in the last 20,000 years.

Eskimo Curlew (Numenius borealis) is probably extinct. It was originally a bird that migrated from the north Canadian Arctic to Argentina and perhaps Chile. The route that this bird took in the fall was south along the Atlantic seaboard of the United States (New England) through the Caribbean and down to South America. In the following spring, the bird migrated north over the central United States (i.e., Nebraska and Iowa) on its way back to Canada.

The Eskimo Curlew was a large brown shorebird with a slightly  downward curved bill. The total length was about twelve to fourteen inches.  

This bird species was unusual in that the entire population appeared to migrate in a single gigantic flock. In the l850s, their abundance in New England led to massive slaughtering for food. The bird was a common item in the New England markets in the fall. However, by l865, the bird was no longer available. In Nebraska flocks covering over forty acres were frequently reported. Hunters would fill wagons with sideboards in the  vicinity of Omaha in the middle l800s. By l911, the species had vanished in Nebraska. There have been reports of recent sightings but these have not been confirmed. It is possible that this species could be confused with a small example of the Hudsonian Curlew.

A detailed history of the extinction of this species can be found in Vanished Species by Davaid Day published by Gallery Books.

Sandpipers (Family Scolopacidae) are a group of 82 species of wading birds. Many species in this group run along sandy shores in search of food.

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.
