Species Info:

This lifeform is found east of the Continental Divide in North America. This lifeform is found north of the Equator in the New World tropics. The black or very dark color will help identify this lifeform.

American Black Rail or Black Crake (Laterallus jamaicensis) is found locally in the United States, Central America, the Caribbean, and western South America. The tiny size, less than six inches, helps identify this small bird.

Rails, Gallinules, and Coots (Family Rallidae) is a worldwide
family of 132 species of primarily wading birds. In 1998, Taylor and van Perlo published a major work on this group of birds.  They counted 150 species of which fifteen had been extinct since 1600; another two species they feel were certainly extinct at the time. These authors contend 133 species are in existance. It is interesting to observe that all of the extinctions occurred prior to 1950 and most all (except for three) occurred prior to 1900. The losses were all from species found on various islands in the various oceans. Many of these species were flightless birds that fell victim to introduced carnivores. However, another thirty-three (probably less two extinct) species are now formally listed as threatened with extinction.

Cranes and Rails (Order Gruiformes) are a worldwide group of 199
species, some of which have recently become extinct. They are medium to large in size and usually associated with water.

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.
