This beautiful bird has been brought to the verge of extinction in 

 this country through the use of its "aigrette pinnies" for millinery 

 American purposes, and is now confined to a tew protected rookeries 



Egret Group f the South. The birds have those plumes only during 



the nesting season, at which time the death of the parent means the 

 starvation of the young. (Reproduced from studies in a rookery of 

 South Carolina. I

In the breeding season the flamingoes congregate in great numbers in 

 their rookeries. There were estimated to be two thousand nests in this 

 Flamingo colony. The flamingoes construct their nests by scooping 

 Group up mud with their bills and packing it down by means of 



bills and feet. The nests are raised to a height of twelve or fourteen 

 inches; this protects eggs and young from disasters due to high w r ater. 

 Only one egg is laid in the nest, and the young is born covered with down 

 like a young duck and is fed by the mother on predigested food. The 

 brilliant plumage of the adult is not acquired until the fifth or sixth 

 molt. (Reproduced from studies in the Bahama Islands.)
