Strutseformede

Strutseformede is a descriptive term, primarily used in the context of paleontology, to denote a group of birds characterized by their ostrich-like features. This classification is not a formal taxonomic rank but rather a way to group birds that share certain ancestral traits, particularly those related to a lack of flight and the development of powerful legs for running. The most prominent member of this group, and the one that gives the term its name, is the ostrich (Struthio camelus).

Birds described as strutseformede typically exhibit several key characteristics. These include reduced or absent wings, a long, unfeathered neck, a small head relative to their body size, and exceptionally strong, elongated legs adapted for terrestrial locomotion. Their plumage is often loose and lacks the interlocking barbules that create a stiff flight surface. While the ostrich is the quintessential example, the term can also encompass other large, flightless birds with similar adaptations, though the precise scope can vary depending on the paleontological or ornithological context.

The evolutionary path of strutseformede birds often involves adaptation to open, arid, or semi-arid environments where flight is less advantageous than rapid escape on foot. Their diet is typically herbivorous or omnivorous, consisting of seeds, fruits, roots, and sometimes insects or small vertebrates. The presence of strutseformede characteristics in the fossil record provides insights into the diversification of avian lineages and the ecological pressures that led to the evolution of flightlessness in various bird groups throughout Earth's history.
