Ostrich in the context of "Ranch"

Bipedalism is a form of terrestrial locomotion where an animal moves by means of its two rear (or lower) limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped /ˈbaɪpɛd/, meaning 'two feet' (from Latin bis 'double' and pes 'foot'). Types of bipedal movement include walking or running (a bipedal gait) and hopping.

Several groups of modern species are habitual bipeds whose normal method of locomotion is two-legged. In the Triassic period some groups of archosaurs, a group that includes crocodiles and dinosaurs, developed bipedalism; among the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds; the birds are members of a clade of exclusively bipedal dinosaurs, the theropods. Within mammals, habitual bipedalism has evolved multiple times, with the macropods, kangaroo rats and mice, springhare, hopping mice, pangolins and hominin apes such as australopithecines, including humans, as well as many other extinct groups evolving the trait independently.

Flightless birds are birds that cannot fly, as they have, through evolution, lost the ability. There are over 60 extant species, including the well-known ratites (ostriches (Struthio), emus (Dromaius), cassowaries (Casuarius), rheas, and kiwis (Apteryx)) and penguins (Sphenisciformes). The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7 g). The largest (both heaviest and tallest) flightless bird, which is also the largest living bird in general, is the common ostrich (2.7 m, 156 kg).

Some domesticated birds, such as the domestic chicken, have lost the ability to fly for extended periods, although their ancestral species, the red junglefowl and others, respectively, are capable of extended flight. A few particularly bred birds, such as the Broad Breasted White turkey, have become totally flightless as a result of selective breeding; the birds were bred to grow massive breast meat that weighs too much for the bird's wings to support in flight.

Ratites (/ˈrætaɪts/) are a polyphyletic group consisting of all birds within the infraclass Palaeognathae that lack keels and cannot fly. They are mostly large, long-necked, and long-legged, the exception being the kiwi, which is also the only nocturnal extant ratite.

The understanding of relationships within the paleognath clade has been in flux. Previously, all the flightless members had been assigned to the order Struthioniformes, which is more recently regarded as containing only the ostrich. The modern bird infraclass Palaeognathae consists of ratites and the flighted Neotropic tinamous (compare to Neognathae). Unlike other flightless birds, the ratites have no keel on their sternum—hence the name, from the Latin ratis ('raft', a vessel which has no keel—in contradistinction to extant flighted birds with a keel). Without this to anchor their wing muscles, they could not have flown even if they had developed suitable wings. Ratites are a polyphyletic group; tinamous fall within them, and are the sister group of the extinct moa. This implies that flightlessness is a trait that evolved independently multiple times in different ratite lineages.

In Abrahamic religions, the Garden of Eden (Biblical Hebrew: גַּן־עֵדֶן‎, romanized: gan-ʿĒḏen; Greek: Εδέμ; Latin: Paradisus) or Garden of God (גַּן־יְהֹוֶה‎, gan-YHWH and גַן־אֱלֹהִים‎, gan-Elohim), also called the Terrestrial Paradise, is the biblical paradise described in Genesis 2–3 and Ezekiel 28 and 31.

The location of Eden is described in the Book of Genesis as the source of four tributaries. Various suggestions have been made for its location: at the head of the Persian Gulf, in southern Mesopotamia where the Tigris and Euphrates rivers run into the sea; and in Armenia. Others theorize that Eden was the entire Fertile Crescent or a region substantial in size in Mesopotamia, where its native inhabitants still exist in cities such as Telassar.

A cover-up is an attempt, whether successful or not, to conceal evidence of wrongdoing, error, incompetence, or other embarrassing information. Research has distinguished personal cover-ups (covering up one's own misdeeds) from relational cover-ups (covering up someone else's misdeeds).

The expression is usually applied to people in positions of authority who abuse power to avoid or silence criticism or to deflect guilt of wrongdoing. Perpetrators of a cover-up (initiators or their allies) may be responsible for a misdeed, a breach of trust or duty, or a crime.

Atef (Ancient Egyptian: 𓄿𓏏𓆑𓋚, romanized: ꜣtf) is the specific feathered white crown of the ancient Egyptian deity Osiris. It combines the Hedjet, the white crown of Upper Egypt, with curly ostrich feathers on each side of the crown for the Osiris cult. The feathers are identified as ostrich from their curl or curve at the upper ends, with a slight flare toward the base. They are the same feather as (singly) worn by Maat. They may be compared with the falcon tail feathers in two-feather crowns such as those of Amun, which are more narrow and straight without curve.

The Atef crown identifies Osiris in ancient Egyptian painting. Osiris wears the Atef crown as a symbol of the ruler of the underworld. The tall bulbous white piece in the center of the crown is between two ostrich feathers. The feathers represent truth and justice. The Atef crown is similar, save for the feathers, to the plain white crown (Hedjet) first recorded in the Predynastic Period and worn as a symbol for pharaonic Upper Egypt.
