Struthideidae

Struthideidae is a family of birds that includes the ostriches, the largest living birds. The family is monotypic, containing only one genus, Struthio, which includes two living species: the common ostrich (Struthio camelus) and the somali ostrich (Struthio molybdophanes). The family is native to Africa, with the common ostrich found in the southern part of the continent and the somali ostrich in the eastern part.

Ostriches are known for their distinctive appearance, with long legs, a long neck, and a large body. They are flightless birds, with the common ostrich being the largest living bird, reaching heights of up to 2.7 meters and weighing up to 156 kilograms. The somali ostrich is slightly smaller, with a height of up to 2.5 meters and a weight of up to 132 kilograms.

Ostriches are omnivorous, feeding on a variety of plants and small animals. They are social birds, living in groups called "parliaments," which can consist of up to 70 individuals. Ostriches are known for their speed and agility, with the common ostrich being able to run at speeds of up to 70 kilometers per hour.

The family Struthideidae is classified within the order Struthioniformes, which also includes the extinct emus and rheas. The family is further classified within the infraorder Paleognathae, which includes the ratites, or flightless birds. The family Struthideidae is one of the most well-known and studied groups of birds, with extensive research conducted on their biology, behavior, and conservation.
