re: duck hunting: what does "call sparingly" mean?

Give them the loudest hail call your lungs can muster.

This was said sarcastically, but it's ok to give a long, loud hail call if they are actually 200 yards away. You do whatever you have to do to get them to notice you. Once they notice you, then the attention shifts towards making them focus on the dekes and not where the calling is coming from (open rice fields). If they notice us and shift towards us we just soft quack and 3-4 note greeting on the edges and occasional feed (real short and choppy, not the roll you hear most do). We do our best to let the decoys do the work and only really call if they swing very wide or seem uninterested.
