You did very well! I find photographing the RWB to be the most difficult and believe me I have ample opportunities to capture them. I can never get them to where you can see their eyes and if I overexpose even the slightest, I blow the white feathers.
Well the engine was still running, in neutral with the brake on :>)) At the wetlands the road is sorta one lane winding around the wetlands. So you can park on the side or stay in vehicle to shoot. Sometimes if you get out, they are spooked and no shot. Leaned across the gear shift, ouch, and got as close to the passenger window as possible and fired away at him.
