This article is dedicated to the study of the structure, ways of formation of bone structures that form the basis of locomotor organs, namely the hip joint, the elucidation of mechanisms of their development, because they provide their reliable functioning. The study of the structural features of the skeleton of birds in comparison to other animals makes it possible to understand the phylogeny as an adaptive process that is the basis of evolution at all.Theoretical generalization of structural features of birds’ hip joint that are characterized by different types of biomorphological adaptations, such as the type and speed of ground movement in the habitat, are presented in the article. This new position allows analyzing the processes of differentiation and transformation of muscles and skeletal elements of birds’ hip joint, which are functioning and developing under the influence of various external factors.The summarized results of the original systematic morpho–functional and morpho–ecological study of hip bones as the main unit of bipedal locomotion of the Class Aves, is given. A detailed comparative description of skeletal elements of birds’ hip joint, that accompanied by unique historical overview which covers more than two–thousand–year period, is provided for the first time. The analysis of some significant morphological structures, which gives clues to the reconstruction of adaptive evolution of any group of birds, is given.
