stood with its legs erect, its body horizontal, and its neck rather ex- 
tended. It frequently reposed on its belly, and stretching its neck, 
rested its long bill on the floor. It spent most of its time in this way, 
or in dressing and arranging its plumage with its long scissors-like bill, 
which it seemed to perform with great ease and dexterity. It re- 
fused every kind of food offered it, and I am persuaded never feeds 
but when on the wing.” 
Dr. Coues says that these birds go in true flocks, 
and not mere loose assemblages like terns, and that 
they are largely nocturnal or crepuscular. “ Their 
mode of feeding is not exactly made out, but it is 
believed they skim over the surface with the body 
inclined downward, the bill open, and the under 
mandible in the water, so they really take their prey 
in a manner analogous to the feeding of whales.”
