Clandestino, I don't think any airline has sop's on avoiding birds, they assume you will not run into other airplanes and birds when they hire you. You avoid other airplanes by looking out the window, just as missing birds and mountains. When you drive your car do you just stare ahead at your lane or do you check to make sure cross traffic isn't running a red light? I use the same techniques in an airplane to try not to hit anything. Remember that idiot in LA that tied balloons to his lawn chair and took to the skies? Now I even look for flying lawn chairs.
