This is very opposite to Wilson's opinion, who says, " that 

 they return to feed theii* young only during the night, in the 

 day they are silent, and wander widely over the ocean;" the 

 males may possibly be abroad during the day whilst the 

 females are sitting, but I am inclined to think that they 

 rarely come out before night, as the fishermen never see them 

 at any other time.
