WHITE WHOOPING CHANE. 125 



running- al.out in circles, or performing other capers, but have also seen tloinesticatcd Cranes 

 equally agile. One kept iu a yard at Cedar Keys, near our camp, not only entertained 

 his master by his grotesque performances, but also took upon himself the duties of a watch 

 dog, and whenever a stranger attempted to pass into the gate in order to reach the house, 

 the Crane would endeavor to oppose his entrance; then if the intruder persisted ;:) his ef- 

 forts, the bird would not hesitate to strike him with his strong beak, and the only w;iy to 

 get by him in safety was to seize the bird by the bill and drag him a sliort distance, when 

 he would retreat, giving vent to his anger in loud screams.

OBSERV.^TIONS. 



Readily known by the large size, white color as described, and rounded naked .space on to|) of head, tliis being scal- 

 loped in the Sandhill. Both .species have the head fully feathered when very young. Di.strihutcd, in summer, throughout 

 the West. Rare in South Central Florida.

HABITS. 



Some yeai's ago, the late Capt. Dummett assured me that the White Whooping Crane 

 occurred on the prairies which lie to the eastward of the Kissimee River and Lake Okeecho- 

 bee, and this report has also been confirmed by others. I have, however, never been fortu- 

 nate enough to meet with a specimen of this fine Crane in Florida, and think that it must 

 be confined to the section mentioned above. 



There :ire some differences in the structure of the trachea of the present species when 

 compared with that of the preceding. The keel in both is wide and well produced for- 

 ward, but in the Sandhill Crane, the trachea only enters it for about two inches, bends up- 

 ward to the level of the body of the sternum, then forward and downward, inclining back- 

 ward, but once more turns forward, emerging just behtw the point ofcatraucc, and curving 

 downward, proceeds in its usual course to the larynx. Thus there is but one convolution 

 iu the keel, which occupies only about seven inches, whereas in the Whooping Crane there 

 arc said to be two distinct convolutions occupying some twenty-eight inches. It would be 

 interesting to note the differences in tone produced by these tracheal modifications. The 

 Whooping Cranes resemble the Sandhills in habit, and are common throughout the West.
