I shot a goose today that was wounded and flew left to right about 250 to 300 yards from me but over a small rise in the field. Waited 20 min then walked over there with the dog and no bird to be seen. The dog tracked the bird from right to left about 400 yards before catching up with it. Wounded geese go walkabout, fast. And I expect many other species of birds do the same.

Nothing is foolproof to a sufficiently talented fool.
