MAN-O'-WAR BIRDS. 43 



mandible with upright horn. Post-breeding plumage : crest replaced by 

 short grayish feathers, upper mandible without horny excrescence. Adults 

 in winter plumage : back of head white ; bill pouch and feet pale yellow 

 instead of orange. Young : white, with gray on top of head and lesser 

 wing coverts. Length : 4 to nearly 6 feet ; extent 8 to nearly 10 feet ; 

 wing 20.00-y25.25, bill 11.05-15.00; weight about 17 Ibs. 



Distribution. North America from latitude 61 to Guatemala. 



Nest. Usually on islands, sometimes a depression in gravel or sand, 

 lined with seaweeds ; but generally a thin layer of sticks and weeds, laid 

 on the ground or on rocks. Eggs : 1 to 3, dull white, like those of the 

 Canada goose, but with rougher shell. 



The white pelican is more a bird of, the interior than of the coast 

 districts, and still breeds in great colonies on a few of the larger 

 lakes. Some of the little islands which used to be covered with 

 nests are abandoned now, the splendid birds having been driven 

 away by wanton persecution. 



The pelicans are eminently social at all seasons, sometimes gather- 

 ing in flocks of many hundreds along the shore, where, by beating 

 the water with their wings, they drive the fish into the shallows, to 

 scoop them up with their wide pouches. At other times they may 

 be seen circling, wheeling, and soaring overhead, in magnificent aerial 

 drill, or riding buoyantly on the surface of the water like a squadron 

 of white ships. VERNON BAILEY.
