Flicker or northern flicker (Colaptes auratus) is found in central and eastern North America from Canada to Florida. This species is also found further west. This can be found from Newfoundland to central Alaska. This is found as far south as northern Mexico, Grand Cayman, and Cuba. This common woodpecker can be identified by its brown back and length of twelve to thirteen inches.

This is a variable species with about 9 different subspecies. Many forms have a black mark on the upper chest. The brown back is crossed with horizontal black lines. The breast is white, and marked with black spots. Most forms have some sort of red mark on their head.

Howard-Moore in 2003 listed 10 different subspecies. However, the subspecies rufipileas of Guadalupe Island is considered probably extinct.

The nominate form is found in the south eastern United States. The subspecies luteus is found from Canada south into the central and eastern United States south to the Gulf of Mexico.

The subspecies nanus is found in north eastern Mexico. The subspecies mexicanus is found in central Mexico. The subspecies mexicanoides is found from southern Mexico into Nicaragua.

The flicker bird genus (Colaptes) is found from Alaska south through the United States into Central and South America as far south as southern Chile and southern Argentina. These are generally large, but not giant woodpeckers. Some are ground feeders and others feed in trees. There are 9 full species, and there are many subspecies in this genus.

In 2003 Howard-Moore covered subspecies in 9 different species.

In 2014 Gorman counted a full 13 species. (This also included a species he moved from Piculus rubiginosus to Colaptes rubiginosus))

With about 216 species of woodpeckers known, we have arbitrarily divided this family into five geographic sections to help facilitate study of this group.

Woodpeckers (Family Picidae) are a family of over 200 species including the familiar woodpecker and some other primitive birds. Most of the species in this family are adapted to searching for food in the wood of trees.

Monroe and Sibley have increased the count to 216 species as of 1993. Howard and Moore in 2003 counted 210 species. Gorman in 2014 counted 239 species.

Several species are quite large and several are almost tiny. The great slaty woodpecker of the Indo-Australian region can reach over 20 inches in length. The extinct ivory billed woodpecker of North America was also about 20 inches in length. The white browed piculet of the China- SE Asian region is less than 4 inches in length.

We have divided the Picidae into 5 major groups. We provided one for each of the five major geographical regions. However, we created an additional 4 special groups following four of the major groups, as we felt the Wrynecks and Piculet groups should be separated out.

Woodpeckers and Toucans (Order Piciformes) are separated from most other birds by an unusual tendon and foot arrangement that includes two forward and two rear pointing toes. There are six families in this order. Most species in this order have unusual bills adapted for their unique way of obtaining food.

Some taxonomists place the puffbirds and jacamars in various places in the taxonomy tree. We have included the puffbirds (Bucconidae) and jacamars (Galbulidae) herein.

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.
