 is loud and clamorous. 



Turning to North America, besides Bewick's 

 swan, the hooper, according to most natural- 

 ists, exists in the northern districts. But the 

 prince of Canino, in his " Birds of Europe 

 and North America," regards the species 

 usually considered as identical with the hooper 

 to be distinct, and registers it as the cygnus 

 Americanus of Sharpless. How far he is cor-

 definite species, the trumpeter swan, (cyc/mis 

 buccinator,) undoubtedly peculiar to North 

 America, and which is the common swan of 

 tke fur countries, whence its skins are im- 

 ported in great numbers into England. It is 

 the species that furnishes the principal part 

 of the swan's down of commerce, and also 

 swan quills. 



The breeding places of the trumpeter swan 

 are chiefly within the arctic circle, whence it 

 migrates southwards on the approach of winter, 

 preceding the flocks of wild geese. The fold
