hey cwackers,
I agree with Bob H to some extent. My buddy has a GSP, but he used to squirt it with a water bottle when it was a pup to keep it from jumping on the couch, chewing things, etc., and now it hates water! So we're left to fend with the two-legged variety: One another!

Like Bob said, follow that bird down and make sure it is stone cold dead before you contemplate a double or following shot on other birds. A double's great for bragging rights but if you only retrieve one bird, what's the point?

Mark your bird based on the landmarks around where it hits the tules/brush/grass. Even if it's a tree branch or the tallest tule, if you see the bird hit it on the way in, you've got your mark. Now play OJ and high step that pond or stream, doing your best to NOT take your eye off the mark. Consider the angle at which the bird was travelling when it hit the tule/branch/brush, pace off a couple steps, and begin your search. Keep in mind that if you simply winged your bird, you'll want to keep an eye aslant for it swimming!

I've hit 3 green heads coming dead at me with one shot. The lead bird landed at my feet, the other two just 10-15' over each shoulder. I lost them both in a 7' tall tule patch not 80' square. I had witnesses! But without a dog...

Good luck, shoot straight, hunt hard.
