The Hrent rises slowly, and when on the wing moves sluggishly 

 for a short distance, and, if not attracted by a distant flock, frequently 

 returns to the place it had left. Its food consists of a marine plant 

 (Zonitrn iniirinii), commonly called 'eel grass.' At low water it is 

 seen industriously at work tearing up its favorite plant. After the 

 tide has risen to such a height as to compel it to reliin|iii-h its voca- 

 tion, it is seen drifting with the current, feeding sumptuously on the 

 fruits of its labor" (Giraud).
