The study was carried out to investigate the effects of some external egg traits on hatchability using classification tree mRapid increase in human population leads to frequent contact with wild animals. Recently, the number of wild animals brought to the clinic of Faculty of Veterinary Medicine increased in consequence of illegal hunting, injury and road accident. In the present study, 16 palpebra inferiores of 8 buzzards (Buteo buteo) were investigated by subgros and histological methods. Palpebra inferioris responsible of covering cornea was longer than superior palpebra and supported with a dense connective tissue structure called tarsal plate. Tarsal plate in the buzzard has a strong structure and suitable form to protect eye. This strong tarsal plate should be kept in mind during surgical approach of inferior palpebra.
