May 28, 2010 · Between toes and ankles birds have a single bone, the tarsometatarsus, that’s the fusion of what would have been ankle (tarsal) and foot (metatarsal) bones if they were mammals. This body part is called the tarsus. Plural is tarsi. Fortunately we can still call it …

Most birds are classified as digitigrade animals, meaning they walk on their toes rather than the entire foot. [3] [4] Some of the lower bones of the foot (the distals and most of the metatarsal) are fused to form the tarsometatarsus – a third segment of the leg, specific to birds.

Explore the complexities of bird leg anatomy with a focus on talons, tarsi, and toes. Understand how these critical components aid in a bird’s survival… ️

The tarsometatarsus is a bone that is only found in the lower leg of birds and some non-avian dinosaurs. It is formed from the fusion of several bones found in other types of animals, and homologous to the mammalian tarsus (ankle bones) and metatarsal bones (foot).

Bird terminology is a gathering of words, terms and phrases describing bird parts, bird habits, bird categories and any and all words used in relation to birds or in the profession of ornithology.

The tarsi, femur, tibia, and toes work together to create a system that allows birds to walk, run, swim, climb, and even fly. Bird legs are marvels of evolution that have adapted over millions of years to suit different environments and lifestyles.

The tarsometatarsus in birds is a compound bone that forms through the lateral fusion and longitudinal growth of three bones late in incubation (for which see Box 31.1), a process that requires an unusual regression of the fibrous layer of the periosteum and fusion of the cellular layers (Namba et al., 2010).
