Metalfab, i had an experience today where i was kicking myself. I was out and about in the car when i decided to stop by a new park area, and noticed it had a little creek running through it.
I grabbed the camera bag, walked over to the creek and noticed there was a duck standing on a concrete divider and was just about ready to dive into the water. I pulled out the camera and noticed i still had the 18-55mm lens on, and i had left my 50-200mm at home. Of course, i wasn't able to get close enough to get any decent shots.
As soon as i got home, the 200mm was put in the bag ready for my next outing, and i was still kicking myself at the missed opportunity.
Your Pileated Woodpeckers are amazing birds, wish we had them in Oz.
From what i've read, aren't these birds hard to capture at the best of times? I think you did a great job given your circumstances.
