18 BIRDS OF THE WORLD 



The Pied-billed Grebe, commonly called Hell-diver, 

 has also a very extensive range, being found at differ- 

 ent seasons of the year in both North and South 

 America. It swims and dives with the greatest ease, 

 often swimming under water with only the tip of the 

 bill exposed. In summer this bird is dark greyish-

 the breast and sides are brown, and the rest of the 

 under parts silver-white.

 the Petrels are long and pointed, and their powers of 

 flight are remarkable. They practically live at sea, 

 seldom coming to land except during the breeding 

 time. 



Of the many different kinds of Petrels, three species 

 are figured; and of these by far the most interesting 

 is the Albatross, one of the largest birds that fly. The 

 Black-browed Albatross is found in Europe and 

 Western America, though its real home is in the 

 southern oceans. Albatrosses commonly breed in 

 large colonies. In the island of Laysan, in the 

 Pacific Ocean, thousands of these birds can be 

 seen, each brooding its single white egg. The nest- 

 ling is covered with white down of extraordinary 

 length, and it is remarkable for the great length of
