" Our bird differs but little in its habits from other oceanic Gulls. 

 Feeding chiefly on fish, but accepting any diet that drifts within range 

 of its keen sight ; drinking salt water in preference to fresh ; breasting 

 a gale with ease and grace — soaring in midair, skimming close above 

 the crested waves, or swooping into the trough for a coveted morsel ; 

 resting upon the rolling billows, and sleeping serenely as they roll, 

 with head tucked snugly under a wing ; wandering in loose flocks, 

 and making comrades of other wanderers ; devoted to mate and young, 

 and attached to all its kin — wherever seen or however employed, the 

 Klttiwake is revealed as a typical gleaner of the sea. 



" The name is derived from the bird's singular cry, which resembles 

 the syllables Mtti-aa, MtU-aa " (Chamberlain).
