RED-HEADED DUCK. 113 



reconnoitre the paddler, and give information, to the rest, of his 

 motions. When the look-out Ducks apprehend danger, the stretching 

 up of their necks is the signal, and immediately the whole squadron, 

 facing to the wind, rise with a noise which may be heard at the distance 

 of half a mile. 



The guns employed in Canvas-back shooting should be of a medium 

 length and calibre ; 'and of the most approved patent breech. My 

 experience has taught me that a barrel of three feet seven inches, with 

 a bore short of seven-eighths of an inch, is quite as effective as one of 

 greater dimensions ; and is certainly more convenient. It may appear 

 a work of supererogation to speak of the quality of powder to be used 

 in this kind of sporting ; and yet so often are shooters deceived in this 

 article, either through penuriousness or negligence, that a word of advice 

 may not be unprofitable. One should obtain the best powder, without 

 regard to price ; it being an indisputable maxim in shooting, but which 

 is too often forgotten, that the best is always the cheapest. 



Species XIX. ANAS FERINA?* 



RED-HEADED DUCK. 



[Plate LXX. Fig. 6, Male.] 



This is a common associate of the Canvas-back, frequenting the same 

 places, and feeding on the stems of the same grass, the latter eating 

 only the roots ; its flesh is very little inferior, and it is often sold in our 

 markets for the Canvas-back, to those unacquainted with the charac- 

 teristic marks of each. Anxious as I am to determine precisely whether 

 this species be the Red-headed Wigeon, Pochard, or Dunf bird of 

 England, I have not been able to ascertain the point to my own satis- 

 faction ; though I think it very probably the same, the size, extent, and 

 general description of the Pochard agreeing pretty nearly with this. 



The Red-head is twenty inches in length, and two feet six inches in 

 extent; bill dark slate, sometimes black, two inches long, and seven-
