Eared Dove (Zenaida auriculata) is found from the Antilles south to southern Argentina and southern Chile. The Eared Dove is also found in Colombia and has been recorded as far north as Panama. This species is considered the replacement species for the north American Mourning Dove.

The Eared Dove can be quite common and millions are poisoned each year at water holes for human food. In Birds of Brazil, Helmut Sick notes that one site produced 300,000 birds in 21 days.

This widespread species has 11 named subspecies. The nominate subspecies is the most southern being found in central Chile and central Argentina.

The subspecies caucae and antioquiae are found in western and north central Colombia respectively. The subspecies ruficauda is found from eastern Colombia to western Venezuela.

The subspecies vinaceorufa is found on Aruba, Curacao, and Bonaire Islands. The subspecies rubripes is found in the Lesser Antilles, Trinidad, and east through Venezuela, the Guyanas to northern Brazil. (This subspecies is also found south into central Colombia.)

The subspecies jessieae is found in the Lower Amazon Valley. The subspecies marajoensis is found in the Amazon estuary. The subspecies noronha is found in north eastern Brazil. The subspecies hypoleuca is found from western Ecuador south into Peru. The subspecies virgata is found in Bolivia and east into Uruguay, northern Argentina, and north to central Brazil.

The New World dove genus (Zenaida) contains 7 species. The familiar mourning dove belongs here. These are typically from 10 to 12 inches in length. Most are generally greyish to brown grey. The Socorro dove (Zenaida graysoni of insular west Mexico is considered extinct.

Goodwin in 1983 counted only 5 species. The southern forms of Zenaida asiatica have been moved to a full species, Zenaida meloda. Zenaida graysoni was previously considered part of the mourning dove (Zenaida macroura).

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 New 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.
