SPECIFIC FEATURES OF THE ILLIAC MUSCLE OF PREDATORY BIRDS

Journal Title: Ukrainian Journal of Veterinary Sciences - Year 2018, Vol 1, Issue 285

Abstract

Interest in the occurrence of a bird's flight flew into the background the study of the adaptation of the pelvic fins of birds. It fully concerns both the skeletal elements and the muscular system of the femur leg. It should also be noted that the initial studies of this issue have shown extremely specific characteristics of the structural elements of the area of the hip joint. This in turn suggests that studies of the pelvic fins of birds are relevant and almost not studied. A paticulary important aspect of research of this issue is the establishment of valid principles and mechanism for the development of the femur of the thigh, taking into account the specific features of locomotion. In this article biomorphological features of the hip joint muscles of predantory birds (white–tailed eagle, common buzz, golden eagle, small hawk, merlin, winter path, andy condor, rhino owl, white owl, eary owl, tawny owl, barn owl) are outlined. It was established that the representatives of this series of degrees of differentation of muscles of the hip joint area due to the stepping type of the bipolar locomotion, as well as the biomorphological festures of the static, which in turn imposes certain imprints on the degree of development of each individual muscle of the hip joint. Also fix points are detailed, presence or absence of porosity is determined. In addition, in order to determine the degree of muscles and muscle groups development, each muscle was weighed. It was found that the extension of muscles of the hip joint of the white–tailed eagle requires considerably greater effort than bending, and of the golden eagle, big hawk, twist and the buzzard, on the contrary, the balge louding during static and locomotive fulls on the bend. Nightly and daytime predantory birds differ not only in the way of life (night or day),body weight ,but also in various manipulations of the limbs, in paticular during hunring for the prey, the force of the extremity during the attack and the method of capture by the claws imposing certain imprints on the development of hip joint bones.
