water and on the sea shore, in warm and temperate 

 climates, but there are less than a dozen species.- 

 The best known is the Common White or Roseate 

 Pelican (Pelecanus onocrotalus) of South-East Europe 

 and the adjacent countries and familiar in cap- 

 tivity ; this has a pinkish blush on its plumage. 

 The purely white Pelican (P. trachyrhynchus) of 

 North America grows a deciduous horn on the bill 

 in the breeding season. The American Brown 

 Pelican is a small species of maritime habits and 

 dark colour ; the only South American kind (P. 

 molince) is very similar. The large Australian 

 Pelican (P. conspicillatus) is pied black and white. 

 No Pelicans are found in Britain or New Zealand 

 and the Pacific Islands:
