From the Latin for "little fork", the furcula is a forked bone, also found in some dinosaurs, located below the neck and formed by the fusion of the two clavicles. Its primary function is in the strengthening of the thoracic skeleton to withstand the rigors of flight .
The Sarus Crane in south Asia is unique in having a significant breeding population using agricultural fields to breed in areas alongside very high density of humans and intensive farming, largely due to the positive attitudes of farmers towards the cranes. [2]
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

The neck plays a role in head-bobbing which is present in at least eight out of 44 orders of birds, including Columbiformes, Galliformes, and Gruiformes. [10] Head-bobbing is an optokinetic response which stabilizes a bird's surroundings as it alternates between a thrust phase and a hold phase. [ 11 ]
Bone mineral density (BMD) is a measure commonly used to quantify bone health. A lower BMD value indicates an increased risk of an osteoporosis or a fracture. [13] There is a large range of factors influencing BMD. Protein consumption has shown to be beneficial for bone density by providing amino acid substrates necessary for bone matrix formation.
The common crane (Grus grus), also known as the Eurasian crane, is a bird of the family Gruidae, the cranes.A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane (Grus virgo) and the Siberian crane (Leucogeranus leucogeranus) that only are regular in the far eastern part of the continent.
Osteopenia, known as "low bone mass" or "low bone density", is a condition in which bone mineral density is low. [1] Because their bones are weaker, people with osteopenia may have a higher risk of fractures , and some people may go on to develop osteoporosis . [ 2 ]
Bones are commonly described with the terms head, neck, shaft, body and base. The head of a bone usually refers to the distal end of the bone. The shaft refers to the elongated sections of long bone, and the neck the segment between the head and shaft (or body). The end of the long bone opposite to the head is known as the base.
