Bristle thigh curlew (Numenius tahitiensis) breeds in western Alaska and is known to migrate to Hawaii. This is known to migrate as far south as French Polynesia and as far west as New Zealand. This has been recorded in eastern Russia and Japan.

This large curlew is from 16 to 17 plus inches (40 to 44 centimeters) in length. There is a black cap, and a white stripe over the eye. The neck is pale, but clearly marked with brown vertical stripes. The upper breast is also makred with vertical brown stripes. The bristle feathers on the thigh will help identify this pale brown species that is marked with darker brown markings. The long bill curves downward.

There are no subspecies.

This bird is covered in the American Bird Conservancy Guide published in 2010. They estimate about 7,000 individuals remain. With such a small number of individuals remaining it is hard to classify this species as to threatened. This bird both breeds and winters in protected areas, so perhaps its population is stable. This lifeform is consdiered vulnerable.

The Tringinae subfamily is found almost world wide. The following genera are included herein:
Limosa (4 species)
Numenius (8 species including one extinct)
Bartramia (1 species)
Tringa (10 species)
Xenus (1 species)
Actitis (2 species)
heteroscellus ( 2 species)
Catoptrophorus (1 species)
Aechmorhynchus (2 species, including one probably extinct)
Prosbonia (2 species, including two probably extinct)

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

To facilitate study of this family, we will divide it into subfamilies as follows:
Scolopacinae - Woodcocks:
Gallinagininae - Snipes:
Tringinae - Godwits:
Arenariinae - Turnstones:
Galidridinae - Knots, Sandpipers, Stints :
Phalaropodinae - Phalaropes

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.

There are many different families herein, and most authors end up with about 18 different families. Other groups included herein include the plovers, curlews, coursers, oyster catchers, jacanas, terns, phalaropes, plovers, stilts and avocets, skimmers, snipes, jaegers, and auks and puffins.

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. Birdlife recognizes 10,027 species as of 2011.

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.

When this project was begun in 1978, we used Austin & Singer for bird taxonomy. Since then, we have adopted many changes, but have kept some older concepts that are still found widely in the literature. Recently, we have used Clements and Howard & Moore. Very recently, we have used Monroe and Sibley for the higher taxonomy of the perching birds.

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.
