Bird Leg Anatomy

The fundamental bones of a birds leg are the femur fibulatibiotarsuss and tarsometatarsus. The upper leg is comprised of the femur and the lower leg contains two bones the tibia and the fibula however in birds the fibula is extremely thin and the tibia is fused together with some of the ankle bones forming a structure called the tibiotarsus.

Most birds are classified as digitigrade animals meaning they walk on their toes rather than the entire foot.

Bird leg anatomy. Most birds have four toes. The anatomy of bird legs and feet is diverse encompassing many accommodations to perform a wide variety of functions. Birds feet are classificated as anisodactyl zygodactyl heterodactyl syndactyl or pamprodactyl9.

The leg bones of birds are the heaviest contributing to a low center of gravity. In a chicken the femur holds the thigh meat and the fibulatibia combination holds the meat of the drumstick. Each toe ends with a curved claw.

A birds skeleton comprises only about 5 of its total body weight.

On a chicken three toes point forward and one is behind.

The first points backwards in most species and consists of a small metatarsal and one phalanx toe bone. Both the human leg and chicken leg have a femur a fibula and a tibia. The metatarsus of a chicken is known as the shank and the chicken walks on its toes.

Even in birds whose dominant means of locomotion is flight there are stresses involved in take off and landing. The upper bones of the foot in turn are fused with the tibia to form the tibiotarsus as over time the centralia disappeared. These are also called the femur tibia and tarsus respectively in an external view of a birds anatomy.

The hallux has 2 phalanges bending in one place only. As in the wing the legs of birds are made up of the same leg bones that we and other vertebrates posses. Although the construction of the wing and the ability to fly are often what capture our attention with bird anatomy the legs and feet of birds are also critical to their lifestyle and success as predators and as prey species.

Some of the lower bones of the foot are fused to form the tarsometatarsus a third segment of the leg specific to birds. The tarsometatarsus forms the upper part of the foot digits make up the toes. Each toe is made up of phalanges.

This aids in flight. Birds have 4 toes some birds only 3 ostrich 2. The hind toe is the hallux toe 1 and is equivalent to the big toe of humans.
