Histological structure and morphometric parameters of sparrow-hawk kidneys (Аccipiter nisus Linnaeus, 1758)

Using the methodological complex the histological structure of the sparrow-hawk (Accipiter nisus Linnaeus, 1758) kidneys was studied. As a result of studies in the kidneys of the presented birds species a relatively thin connective tissue capsule was established, the average density (18-22 instance per conventional unit of area) of renal corpuscles in the cortical substance, a change in the structure of cells that form distal convoluted and distal direct tubules from prismatic and cubic to polymorphic, the presence of proximal and distal convoluted tubules are signs of a violation of protein and fat metabolism. The revealed structural changes in the structure of the organ directly correlate both with the type of trophic relationships (diet), individual characteristics of the organism, habitat conditions, lifestyle and behavior of the bird.
