BABY ALCATRAZ at left is larger and 

 heavier than a full grown domestic 

 goose. Before these pelicans acquire 

 adult plumage they often are heavier 

 than their parents. Parent birds feed 

 them well until the young are able to 

 fly to sea and feed themselves. Above, 

 and below, are young and adult Pele- 

 canus thagus, an exotic species of peli- 

 can gaudily colored and somewhat 

 larger than the common California 

 brown pelican. On the opposite page 

 are terraced sides of North Guahape 

 Island, with hosts of guonayes at rest 

 for the night. 



ADULT PELICAN with a broken 

 wing found on Lobos de Afuera 

 island in starved condition was 

 rescued and nursed back to 

 health by Karl Koch, ornitholo- 

 gist of the expeditions.
