the gross anatomy of larynx, trachea and syrinx in the long-legged buzzard (buteo rufinus).five long-legged buzzards (buteo rufinus), weighing 475-570 g, were used in this study. it was determined that long-legged buzzards' larynx is composed of three different cartilages. among these cartilages, the cricoid and procricoid cartilages were single and the arytenoid cartilage was double. the partially ossified corpus and ala of the cricoid cartilage were connected with cartilaginous plate. trachea was formed up of complete cartilage circles. the tracheal cartilages were notched in dorsal ...200717266664
anatomical and scanning electron microscopic investigations of the tongue and laryngeal entrance in the long-legged buzzard (buteo rufinus, cretzschmar, 1829).this research aimed to examine the morphological features of the tongue and laryngeal entrance of long-legged buzzard by macroscopic and scanning electron microscopic methods. two adult buzzards were used as material. the tongue was fairly elongated and terminated in oval shovel-like apex. scale-like projections were localized on the apex and body of tongue. both lateral sides of lingual body were contained considerably long thread-like projections. many orifices of lingual posterior salivary gl ...201222496047
the branching pattern of the aortic arch in the long-legged buzzard (buteo rufinus cretzschmar 1829).the aim of this study was to investigate the vascular branching morphology of the aortic arch in the long-legged buzzard. for this purpose, two long-legged buzzards were evaluated in this study. the latex injection method was used to investigate the branching of the aortic arch. two innominate brachiocephalic trunks branched continually from aortic arch caudoventral to the primary bronchi and ventral to the syrinx. the left subclavian artery gave rise to sternoclavicular, thoracic, axillary and ...201424136451
the long term response of birds to climate change: new results from a cold stage avifauna in northern england.the early mis 3 (55-40 kyr bp associated with middle palaeolithic archaeology) bird remains from pin hole, creswell crags, derbyshire, england are analysed in the context of the new dating of the site's stratigraphy. the analysis is restricted to the material from the early mis 3 level of the cave because the upper fauna is now known to include holocene material as well as that from the late glacial. the results of the analysis confirm the presence of the taxa, possibly unexpected for a late ple ...201525992609
