Abstract:The Red-crowned Crane, the White-naped Crane, the Hooded Crane and the Siberian? Crane are compared with respect to the morphology of their tracheael loopings in the carina>. sterni of the sternum. The trachea of the Siberian Crane is confined only to the rostrum that occupies the anterior half of the carina sterni, not extending, backward into the body of carina sterni. The looping trachea winds below and behind the rostrum, not concealing in the rostrum. The two tubes of the looping trachea loop synchronously. With regard to these characters, the Siberian Crane differs essentially from the other three species of cranes and resembles the Wattle Crane. We are thus in favor of separating the Siberian Crane from the genus, Grus, and putting it with the Wattle Crane under the genus Bugeranus.
Keywords:Crane  sternum  Pectoral girdle  Comparision  Carina sterni
