Pied imperial pigeon (Ducula bicolor) is found in the Nicobar Islands. This is also found in SE Asia, Malaysia, the Philippines, and Indonesia including Sumatra, Java, and Sulawesi as far east as New Guinea. This is a spectacular 16 inch white bird with a black tipped tail and black tipped wings.

There are 4 recognized subspecies for this life form. The nominate form, Ducula bicolor bicolor, is found from the Andaman and Nicobar Islands to Burma, Malaysia, the Philippines, Indonesia, and as far east as New Guinea. The subspecies luctuosa is found on Sulawesi (Celebes) and nearby islands. The subspecies spilorrhoa is found from Aru to coastal New Guinea and south into Australia. The subspecies subflavescens is found in the Bismarck and Admiralty Islands.

Modern taxonomist have moved the two most eastern subspecies into full species as D. spilorrhoa and D. subflavsecens.

The zoo images are of an unrecognized subspecies.

The imperial pigeon genus (Ducula) is found from India east into SE Asia and China and south to Malaysia and the Philippines. This is also found in Indonesia as far east as New Guinea. There are 38 species and several subspecies. These are generally large and somewhat spectacular birds.

With over three hundred species in the pigeon and dove family (Columbidae) found world wide, we have broken this family into two parts based on geographical origin with the Old World versus the New World as the criteria. This is the Old World portion.

Pigeon and Dove group (Family Columbidae) are a group of about 290 species of birds that are found worldwide.

Pigeons and Doves (Order Columbiformes) contains three families. The dodos (Family Raphidae) are extinct. The other families are the sandgrouse (Family Pteroclidae) and pigeons (Family Columbidae).

Clements in 2007 counted 308 pigeons and doves and Clements also counted 16 sandgrouse. (He, however, placed the sandgrouse in their separate order, Pterocliformes.)

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.
