Lammergeir or bearded vulture (Gypaetus barbatus) is found widely in the Eurasian area as far east as the Himalayas and Pakistan and also widely in Africa. This vulture has black wings, a pale breast, and a paler head and neck. The head is somewhat white with black markings, and the front neck is somewhat pale orange-brown. This 40 to 46 inch vulture when flying shows black on the leading edge of the wings and grey on the feathers. However, the young birds show a black head and neck. They also show a darker color overall. Also, the breast of young birds can show a dark reddish brown.

Howard and Moore (2003) recognize three subspecies. The nominate subspecies G. barbatus barbatus is found in northwestern Africa. The subspecies aureus is found from southern Europe east to the Altai Mountains, Tibet, and Nepal. The final subspecies Gypaetus barbatus meridionalis is found in Yemen and eastern Africa south to South Africa.

The bearded vulture genus (Gypaetus) contains a single species. This is a large vulture about 40 to 45 inches (102 - 114 cm) in length. In flight, the ventral wings and tail are black, and the under body is white with a yellowish upper breast. The tail has an unusual diamond shape. This bird drops bones from great heights to break them apart so that it can eat the marrow.

This group of large birds includes the Old World carrion eaters. There are about 15 now to 16 species in this subfamily. However, subfamily boundaries are not clearly defined, and counts can vary. Although these birds appear similar to the North American vultures (buzzards), the Eurasian and African group appears to have descended more recently from something related to an eagle.

Hawks and Eagles (Family Accipitridae) are a group of 205 species found in most areas of the world. Actually, the common terms of eagle, hawk, kite, buzzard, and vulture are rather loosely used, and consequently, are not much help in understanding this family. Here, this family has been separated into seven groups: typical hawks, Old World vultures, eagles and related hawks, fish eagles, kites, harriers and marsh hawks, and a misc. group. A more precise division might be:
Aegypinae - Old World Vultures -
Elaninae - White Tailed Kites - 7 species
Perninae - Swallowtailed and Hook Billed Kites
Milvinae - True kites -
Accipitrinae - Hunting hawks - 40 species
Buteoninae - Large hawks and eagles - 90 species
Circinae - Harriers and marsh hawks - 17 species
Circaetinae - Serpent eagles

There is no universal agreement on the division of this group, and some authors lump them altogether. We hope our arbitrary separation helps in the study of this group.

Birds of Prey (Order Falconiformes) group contains the eagles, hawks, falcons, Old World vultures, and related birds. The majority of the species in this group feed on small animals, fish, and other birds. A few species eat dead animals. Most of them are excellent fliers and have very strong legs and claws for grasping their prey. There are about 239 species in the hawk and eagle group and about 61 species in the falcon group. When you include the unique osprey and the unique secretary bird, you total about 302 species more or less depending upon a few controversial subspecies.

(The 7 species of New World vultures have recently been placed near the pelicans and storks and were not counted in our 302 number. However, for historical reasons we have left those vultures below here, as our purpose is defining species, and helping users navigate the large number of species.)

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.
