15-7-2025 AMSTERDAM ZOO, HOLLAND - COMMON OSTRICH (Struthio camelus)

The common ostrich (Struthio camelus), or simply ostrich, is a species of flightless bird native to certain areas of Africa. It is one of two extant species of ostriches, the only living members of the genus Struthio in the ratite group of birds. The other is the Somali ostrich (Struthio molybdophanes), which has been recognized as a distinct species by BirdLife International since 2014, having been previously considered a distinctive subspecies of ostrich.

The common ostrich belongs to the order Struthioniformes. Struthioniformes previously contained all the ratites, such as the kiwis, emus, rheas, and cassowaries. 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 now classified as the only members of the order. Phylogenetic studies have shown that it is the sister group to all other members of Palaeognathae, and thus the flighted tinamous are the sister group to the extinct moa] It is distinctive in its appearance, with a long neck and legs, and can run for a long time at a speed of 55 km/h (34 mph) with short bursts up to about 97 km/h (60 mph), the fastest land speed of any bipedal animal and the second fastest of all land animals after the cheetah The common ostrich is the largest living species of bird and thus the largest living dinosaur. It lays the largest eggs of any living bird (the extinct giant elephant bird (Aepyornis maximus) of Madagascar and the south island giant moa (Dinornis robustus) of New Zealand laid larger eggs). Ostriches are the most dangerous birds on the planet for humans, with an average of two to three deaths being recorded each year in South Africa.

The common ostrich's diet consists mainly of plant matter, though it also eats invertebrates and small reptiles. It lives in nomadic groups of 5 to 50 birds. When threatened, the ostrich will either hide itself by lying flat against the ground or run away. If cornered, it can attack with a kick of its powerful legs. Mating patterns differ by geographical region, but territorial males fight for a harem of two to seven females.

The common ostrich is farmed around the world, particularly for its feathers, which are decorative and are also used as feather dusters. Its skin is used for leather products and its meat is sold commercially, with its leanness a common marketing point.

The Common ostrich (Struthio camelus), or simply ostrich, is a species of flightless bird native to certain large areas of Africa and is the largest living bird species. 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 (Struthio molybdophanes), which was recognized as a distinct species. The ostrich is distinctive in its appearance and can run for a long time at a speed of 55 km/h (34 mph) with short bursts up to about 70 km/h (40 mph), the fastest land speed of any bird. It is the largest living species of bird and the largest living dinosaur. It lays the largest eggs of any living bird (the extinct elephant birds of Madagascar and the giant moa of New Zealand laid larger eggs).

The feathers of adult males are mostly black, with white primaries and a white tail. However, the tail of one subspecies is buff. Females and young males are grayish-brown and white. The head and neck of both male and female ostriches are nearly bare, with a thin layer of down. The skin of the female's neck and thighs is pinkish gray, while the male's is gray or pink dependent on the subspecies. The long neck and legs keep the head of these birds up to 2.8 m (9 ft 2 in) above the ground, and their eyes are said to be the largest of any land vertebrate - 50 mm (2 in) in diameter - helping them to see predators at a great distance. The eyes are shaded from sunlight from above. Their skin varies in color depending on the subspecies, with some having light or dark gray skin and others having pinkish or even reddish skin. The strong legs of the common ostrich are unfeathered and show bare skin, with the tarsus (the lowest upright part of the leg) being covered in scales: red in the male, black in the female. The tarsus of the common ostrich is the largest of any living bird, measuring 39 to 53 cm (15+1⁄2 to 21 in) in length. The bird is didactyl, having just two toes on each foot (most birds have four), with the nail on the larger, inner toe resembling a hoof. The outer toe has no nail. The reduced number of toes is an adaptation that appears to aid in running, useful for getting away from predators. New chicks are fawn in color, with dark brown spots. After three months they start to gain their juvenile plumage, which is steadily replaced by adult-like plumage during their second year. At four or five months old, they are already about half the size of an adult bird, and after a year they reach adult height, but not till they are 18 months old will they be fully as heavy as their parents.

The common ostrich (Struthio camelus), the planet's largest bird, is a flightless avian native to Africa. It is a member of the ratite family, which includes other flightless birds like emus and kiwis. The ostrich is known for its impressive size, long neck, and powerful legs, which allow it to reach speeds of up to 70 km/h (43 mph) in short bursts. Males are typically larger than females and boast striking black and white plumage, while females are predominantly brown.

Adult males are characterized by their black feathers with white wings and tail. Females and young males are more subdued in color, displaying grayish-brown feathers. The ostrich's head and neck are sparsely feathered, revealing their skin, which can vary from gray to pinkish tones. They have large eyes, adapted for spotting predators at great distances, and long, muscular legs with two-toed feet.

Ostriches are adapted to a variety of habitats, from savannas to deserts across Africa. They are capable of surviving in extreme conditions, from the scorching heat to areas with scarce water.

Once found throughout Africa and parts of Asia, the common ostrich's range has been reduced due to hunting and habitat loss. Today, they are primarily found in sub-Saharan Africa, with some populations in North Africa and the Sahel region.

Ostriches are nomadic, often traveling in small groups that can range from 5 to 50 individuals. They are known for their running ability, using their speed as a primary defense mechanism. When threatened, they may lie flat against the ground to avoid detection or deliver powerful kicks to defend themselves.

The common ostrich produces distinct vocalizations, including booming calls by males during the mating season, which can be heard over long distances.

Ostriches have complex mating behaviors, with males courting females through elaborate dances and displays. They are known for their communal nesting practices, where several females may lay their eggs in a single nest for incubation.

The Somali ostrich (Struthio molybdophanes), once considered a subspecies, is now recognized as a separate species. It can be distinguished by its blue-gray neck and legs.

Ostriches are omnivores, primarily consuming plant matter such as seeds, shrubs, and fruits, but they will also eat invertebrates and small reptiles. They lack teeth and ingest pebbles to aid in grinding food in their gizzard.

The common ostrich is classified as Least Concern by the IUCN, though certain subspecies, like the North African ostrich, are under greater threat and are listed in CITES Appendix I, which restricts international trade.
