AND PERSONALITY 



effort in bending its neck to scoop into its capacious bill 

 small Crustacea, then tilting its head to filter the brackish 

 water through the lamellae of its lower jaw. 



The flamingoes in thousands may leave one brackish 

 volcanic lake to search out food in another. One night in 

 Maji Moto we heard the whir of the untold numbers of 

 their wings and saw them for hours silhouetted in graceful 

 flight across the pale face of the moon. But the flamingo of 

 Africa is not a migratory bird. 



As one would expect from a life of such easy feeding, the 

 adrenal and thyroid glands of the flamingo are nearly equal 

 in size (0.51 to 0.50). 



The Egyptian goose, in contrast, has to search out its 

 food. It frequents streams and pools and small lakes, where 

 it feeds on grass, algae, and minute animal life. In contrast 

 to the flamingo, the Egyptian goose is "quarrelsome." It 

 bears an adrenal-thyroid pattern of 42 to 34.
