ostrich : a swift-footed 2-toed flightless ratite bird (Struthio camelus) of Africa that is the largest of existing birds and often weighs 300 pounds (140 kilograms) — Webster   See also   OneLook


Ostriches are a family, Struthionidae, of flightless birds. Ostriches first appeared during the Miocene epoch, though various Paleocene, Eocene and Oligocene fossils may also belong to the family. Ostriches are classified in the ratite group of birds, all extant species of which are flightless, including the kiwis, emus, and rheas. Traditionally the order Struthioniformes contained all the ratites. However, recent genetic analysis has found that the group is not monophyletic, as it is paraphyletic with respect to the tinamous, so the ostriches are classified as the only members of the order. There are two extant species of ostrich, the common ostrich and Somali ostrich, both in the genus Struthio, which also contains several species known from Holocene fossils such as the Asian ostrich. The common ostrich is the largest living bird species, and other ostriches are among the largest bird species ever. — Wikipedia

Ornithology is a branch of zoology that concerns the methodological study and consequent knowledge of birds with all that relates to them. A wide range of tools and techniques are used in ornithology, both inside the laboratory and out in the field. Most biologists who consider themselves to be “Ornithologists” study specific categories, such as Anatomy, Taxonomy, or Ecology lifestyles and behaviors. — Wikipedia

    Madagascar's extinct elephant birds—the largest birds ever to have lived—have captured public interest for hundreds of years. Little is known about them due to large gaps in the skeletal fossil record.

    More than 1,200 years ago, flightless elephant birds roamed the island of Madagascar and laid eggs bigger than footballs. While these ostrich-like giants are now extinct, new research from CU Boulder and Curtin University in Australia reveals that their eggshell remnants hold valuable clues about their time on Earth.

    Scientists at Nagoya University in Japan have developed an index to estimate how a bird uses its wings for flight or other locomotion by measuring the strength of the coracoid bone and the animal's body mass. It should improve our understanding of how extinct animals used their wings and the different patterns of wing-propelled locomotion that emerged as birds evolved. Their findings were published in the Journal of Anatomy.

    The ancient Egyptians believed that when we died, our spiritual body sought out an afterlife similar to this world. But entry into this afterlife wasn't guaranteed; it first required a perilous journey through the underworld, followed by an individual last judgment. For this reason, relatives and embalmers did everything they could to ensure that their loved one might reach a happy destination.
