 Formerly this area was an arid place with a characteristic desert 

 bird fauna. Now the ranchmen have irrigated the land 

 an Joaquin ^^^ aquatic bird life abounds. This group is a good illust- 

 ration of the influence of man on the bird life of a region. 

 In the breeding season the flamingos congregate in great numbers in 

 their rookeries. There were estimated to be two thousand 

 ammgo nests in this colony. The flamingos construct their nests 



by scooping 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 water. 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 moult. (Reproduced from studies in the Bahama 

 Islands.) 



In this group is shown a portion of a coral islet on which 



Booby and three thousand boobies and four hundred man-of-war birds 



BirdWoup were nesting, the former on the ground, the latter in the sea 



grape bushes. (Reproduced from studies in the Bahama 



Islands.) 



The abundance of bird life in one of these rookeries is quite astound- 

 ing. In this group are roseate spoonbills, snowy egrets, 

 Florida American egrets, little blue herons, Louisiana herons, 



Group^^ ibises, cormorants and water turkeys. Because of the 



great inaccessibility of this island it has been one of the 

 last places to escape the depredations of the plume-hunter. (Repro- 

 duced from studies in the Everglades of Florida.) 



The golden eagle is one of the most w^idely distributed of birds.
