Ducks have better eyesight than us. If you can see them, chances are they can see you. High-flying ducks have a special advantage in seeing you or anything unnatural about your decoys or blind. Ducks are attracted to decoys by their color as well as their shape and formation. So the next time you want some pictures of theis amazing creatures remember they are smart.
Ducks are mostly concerned with moving objects.
Even if you are caught in the open, remain motionless and the birds may still come within range. If possible, work with the wind. Ducks rarely decoy or come into the same spot two days in a row, especially if there has been heavy shooting or a heavy amount of people. Ducks are enormous eaters and will sometimes forget about danger if good food is available. This can be seen in city parks where even wild ducks can come within range of people just for food.
