This lifeform is generally found west of the Continental Divide in North America This lifeform is found in Mexico.

Painted Redstart (Myioborus pictus or Setaphaga picta) breeds primarily in Mexico but also in the United States in Texas, New Mexico and Arizona. This striking bird can be recognized by its black color, red breast and white wing patch. It measures five-inches.

Wood Warblers (Parulidae Family) are a group of small birds that
originated in the New World. There are less than 120 species in this family. There is recent concern in North America that many of these wonderful birds might become extinct.

One of their enemies is the Cowbird. Although bird watchers have for a long time known the egg-laying habits of Cowbirds, it is only recently that its importance and implications have been understood. Cowbirds will fly into a woods for several miles to lay their eggs in the nests of other birds. The larger and more aggressive hatchlings are then raised by the unsuspecting foster parents, to the detriment of their own young.

Patchworks of small woods and small forest preserves throughout the United States are not sufficient in size to protect these species from Cowbirds. Since most Warblers return to the same site each year to breed, a local extinction becomes a permanent extinction for a given region. Efforts have been made by conservation groups to create areas to serve as havens for members of this family.

Perching Birds (Order Passeriformes) comprise about sixty percent of the world's known species of birds. These 5,000 or so species are broken into many families without very clear distinctions between them. A common characteristic of this order is three forward toes and one reverse pointing toe. Most of species are also characterized by a tendon locking mechanism that permits their feet to lock onto branches when they relax. The families have arbitrarily been placed in alphabetical 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.
