TREADING WATER, AIAEEARD FASHION 



Occasionally, after swimming about on the surface of the water for a considerable time, 

 these Ducks stand erect for a moment and fan their wings rapidly, apparently for the same 

 reason that people yawn and stretch after sitting long in one position.

MAEEARDS AND PINTAILS IN A WIRE-MESH TRAP SET ON THE ICE 



Pintails are trimmer than most other Ducks, with longer, slimmer necks and a more elegant 

 and dignified carriage. They are extremely shy and quick to take alarm and, not possessing^any 

 great degree of curiosity, they are not easily fooled by decoys. This baited trap was about lOO 

 feet long and in one day caught 414 Ducks.
