Struthio orlovi is an extinct species of ostrich bird from the Miocene of Moldavia. [2]
The common ostrich, or simply ostrich, is a species of flightless bird native to certain large areas of Africa. It is one of two extant species of ostriches, the only living members of the genus Struthio in the ratite order of birds. The other is the Somali ostrich, which was recognized as a distinct species by BirdLife International in 2014 having been previously considered a distinctive subspecies of ostrich.
Struthionidae is a family of flightless birds, containing the extant ostriches and their extinct relatives. The two extant species of ostrich are 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 more widespread of the two living species, and is the largest living bird species. The extinct genus Pachystruthio from the Late Pliocene-Early Pleistocene of Eurasia is one of the largest birds ever.
Flightless birds are birds that, through evolution, lost the ability to fly. There are over 60 extant species, including the well-known ratites and penguins. The smallest flightless bird is the Inaccessible Island rail. The largest flightless bird, which is also the largest living bird in general, is the common ostrich.
Ostriches are large flightless birds. They are the heaviest and largest living birds, with adult common ostriches weighing anywhere between 63.5 and 145 kilograms and laying the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. They are farmed worldwide, with significant industries in the Philippines and in Namibia. Ostrich leather is a lucrative commodity, and the large feathers are used as plumes for the decoration of ceremonial headgear. Ostrich eggs have been used by humans for millennia.
Palaeognathae is an infraclass of birds, called paleognaths or palaeognaths, within the class Aves of the clade Archosauria. It is one of the two extant infraclasses of birds, the other being Neognathae, both of which form Neornithes. Palaeognathae contains five extant branches of flightless lineages, termed ratites, and one flying lineage, the Neotropic tinamous. There are 47 species of tinamous, five of kiwis (Apteryx), three of cassowaries (Casuarius), one of emus (Dromaius), two of rheas (Rhea) and two of ostriches (Struthio). Recent research has indicated that paleognaths are monophyletic but the traditional taxonomic split between flightless and flighted forms is incorrect; tinamous are within the ratite radiation, meaning flightlessness arose independently multiple times via parallel evolution.
Ochodaeidae, also known as the sand-loving scarab beetles, is a small family of scarabaeiform beetles occurring in many parts of the world.
The Arabian ostrich, Syrian ostrich, or Middle Eastern ostrich is an extinct subspecies of the ostrich that lived on the Arabian Peninsula and in the Near East until the mid-20th century.
The Phytoseiidae are a family of mites which feed on thrips and other mite species. They are often used as a biological control agent for managing mite pests. Because of their usefulness as biological control agents, interest in Phytoseiidae has steadily increased over the past century. Public awareness of the biological control potential of invertebrates has been growing, though mainly in the US and Europe. In 1950, there were 34 known species. Today, there are 2,731 documented species organized in 90 genera and three subfamilies.
The Somali ostrich, also known as the blue-necked ostrich, is a large flightless bird native to the Horn of Africa. It is one of two living species of ostriches, the other being the common ostrich. It was also previously considered a subspecies of the common ostrich, but was identified as a distinct species in 2014.
The Asian or Asiatic ostrich, is an extinct species of ostrich that lived during the Neogene period on the Indian subcontinent.
Pachystruthio is a genus of extinct bird which lived in Eurasia from the Late Pliocene to the Middle Pleistocene. Its fossils have been found in Hungary, Greece Crimea, Georgia, and China. The genus contains three species: P. pannonicus, P. dmanisensis, and P. transcaucasicus, which were all formerly placed with the ostrich genus, Struthio. An incomplete femur from the Nihewan Formation (China) has been assigned to Pachystruthio indet. P. dmanisensis has been estimated standing 3.5 meters tall and weighing up to 450 kg (990 lb), making it much larger than the modern ostrich and one of the largest known birds.
Orientornis is an extinct species of ratite from the Miocene of China.
Struthio wimani is an extinct species of ratite bird from the Pliocene of China.
An ostrich is a type of large flightless bird.
The North African ostrich, red-necked ostrich, or Barbary ostrich is the nominate subspecies of the common ostrich from West and North Africa. It has the largest average size among the subspecies of ostriches, making it the largest living bird.
The Masai ostrich, also known as the East African ostrich is a red-necked subspecies variety of the common ostrich and is endemic to East Africa. It is one of the largest birds in the world, second only to its sister subspecies Struthio camelus camelus. Today it is hunted and farmed for eggs, meat, and feathers.
This is a list of the tallest extant birds according to maximum height. Birds range from a tiny bee hummingbird, which is only 5–6 cm (2.0–2.4 in), to the giant African ostrich, almost 280 cm (9.2 ft) in height.
The egg of the ostrich is the largest of any living bird. The shell has a long history of use by humans as a container and for decorative artwork, including beads. The eggs are not commonly eaten.
Struthio anderssoni, also known as the East Asian ostrich, is an extinct species of ostrich that lived in the Pleistocene and Holocene in China and Mongolia. In 2023, based on a re-examination of cast of a femur, it was suggested that this species be moved the genus Pachystruthio.
