Geococcyx
The roadrunners (genus ''Geococcyx''), also known as chaparral birds or chaparral cocks, are two species of fast-running ground cuckoos with long tails and crests. They are found in the southwestern and south-central United States, Mexico and Central America, usually in the desert. Although capable of flight, roadrunners generally run away from predators. On the ground, some have been measured at . Species The subfamily Neomorphinae, the New World ground cuckoos, includes 11 species of birds, while the genus ''Geococcyx'' has just two: Morphology The roadrunner generally ranges in size from from tail to beak. The average weight is about . The roadrunner is a slender, black-brown and white-streaked ground bird with a distinctive head crest. It has long legs, strong feet, and an oversized dark bill. The tail is broad with white tips on the three outer tail feathers. The bird has a bare patch of skin behind each eye; this patch is shaded blue anterior to red posteri ...

Geococcyx Californianus
The greater roadrunner (''Geococcyx californianus'') is a long-legged bird in the cuckoo family, Cuculidae, from the Aridoamerica region in the Southwestern United States and Mexico.

The oldest known fossil comes from a cave in New Mexico, estimated at an age of 33,500 years. In the La Brea Tar Pits, fragments from 25 greater roadrunner fossils have been found. Several other fossils are also known from Santa Barbara County, Santa Barbara and Kern County, Kern counties, as well as Northern Mexico Bioregion, Northern Mexico. Prehi ...

Cuckoo
Cuckoos are birds in the Cuculidae ( ) family, the sole taxon in the order Cuculiformes ( ). The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals, and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae, respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species, which are divided into 33 genera. The cuckoos are generally medium-sized, slender birds. Most species live in trees, though a sizeable minority are ground-dwelling. The family has a cosmopolitan distribution; the majority of species are tropical. Some species are migratory. The cuckoos feed on insects, insect larvae, and a variety of other animals, as well as fruit. Some species are brood parasites, laying their eggs in the nests of other species and giving rise to the terms " cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neomorphinae
The Neomorphinae are a Family (biology), subfamily of the cuckoo family, Cuculidae. Members of this subfamily are known as New World ground cuckoos, since most are largely Terrestrial animal, terrestrial and native to the Americas. Only ''Dromococcyx'' and ''Tapera'' are more Arboreal locomotion, arboreal, and these are also the only brood parasitic cuckoos in the Americas, while the remaining all build their own nests.

Zygodactyly
In biology, dactyly is the arrangement of digits (fingers and toes) on the hands, feet, or sometimes wings of a tetrapod animal. The term is derived from the Greek word () meaning "finger." Sometimes the suffix "-dactylia" is used. The derived adjectives end with "-dactyl" or "-dactylous." As a normal feature Pentadactyly Pentadactyly (from Greek "five") is the condition of having five digits on each limb. It is traditionally believed that all living tetrapods are descended from an ancestor with a pentadactyl limb, although many species have now lost or transformed some or all of their digits by the process of evolution. However, this viewpoint was challenged by Stephen Jay Gould in his 1991 essay "Eight (or Fewer) Little Piggies," where he pointed out polydactyly in early tetrapods and described the specializations of digit reduction. Despite the individual variations listed below, the relationship is to the original five-digit model. In reptiles, the limbs are pentadacty ...

United States Fish And Wildlife Service List Of Endangered Species Of Mammals And Birds
This is a list of the bird and mammal species and subspecies described as endangered by the United States Fish and Wildlife Service. It contains species and subspecies not only in the U.S. and its territories, but also those only found in other parts of the world. It does not include endangered fish, amphibians, reptiles, plants, or invertebrates. The complete list can be found in the U.S. Code of Federal Regulations Title 50 Part 17. The listings for status are E for endangered or T for threatened. Species or subspecies may also be endangered or threatened because they are sufficiently similar in appearance to endangered or threatened species or subspecies and are marked for "similarity of appearance" as E(S/A) or T(S/A). Threatened species are animals and plants that are likely to become endangered in the foreseeable future. Identifying, protecting, and restoring endangered and threatened species and subspecies are the primary objectives of the U.S. Fish and Wildlife ...

Woodland
A woodland () is, in the broad sense, land covered with woody plants (trees and shrubs), or in a narrow sense, synonymous with wood (or in the U.S., the '' plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and Australian English explained below). Some savannas may also be woodlands, such as ''savanna woodland'', where trees and shrubs form a light canopy. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana ha ...

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conse ...

Johann Georg Wagler
Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011). Johan Georg Wagler was born on 28 March 1800, in the city of Nuremberg, where the Chancellor of the City Court was Wagler's father (Wagler, 1884).
