MORPHO-CYTOCHEMICAL AND ULTRASTRUCTURAL CHARACYERIZATION OF PERIPERAL THROMBOCYTES OF ROADSIDE HAWK Buteo magnirostris GMELIN, 1788) (AVIAN, FALCONIFORM)

Basic hematological information about the avian in its natural habitat is limited. In this study we aimed at investigating, in the peripherical blood of the roadside hawk, Buteo magnirostris, the number of thrombocytes and their morphological, cytochemical and ultrastructural aspects. Blood smears w...
