TOTIPALMATE SWIMMERS 



113. Red-billed Tkui'kj Biuv. Phcethon cethereus. 



Range. — Tropical seas, chiefly in the Pacific Ocean ; nortli to southern 



California. 



They breed on several islands in the Gulf of California. This species differs 



from the preceding in having a red bill, and the back being barred vvrith black. 



Their plumage has a peculiar satiny appearance and is quite dazzling when 



vievired in the sunlight. They 

 are strong fliers and are met 

 with, hundreds of miles from 

 land. They often rest upon the 

 water, elevating their long tails 

 to keep them from getting wet. 

 They nest, as do the preceding 

 species, on rocky islands and 

 are said to also build their nests 

 in trees or upon the ground. 

 The single egg that they lay 

 has a creamy ground and is mi- 

 nutely dotted with chestnut.

Range.^Tropical regions of the Pacific and Indian Oceans, accidental off 



the coast of Lower California. 



This is a singularly beautiful species resembling the latter except that the 



central tail feathers are bright red, with the extreme tips white. During 



August and September they 

 breed in large colonies on 

 small islands in the South 

 Seas. On Mauritius Island 

 they build their nests either 

 in the trees or place them on 

 the ground; the nest is made 

 of seaweed, sticks and weeds; 

 numbers of them nest on 

 Laysan Is., of the Hawaiian 

 group, concealing their nests 

 on the ground under over- 

 hanging brush.
