Nice shots. I particularly like the pintail spring into flight and the moon shot. What focal length, f stop, shutter speed and ISO did you use for each of these? I couldn't retrieve that information.
Also, on the pintail, did you do any Post workup on that photo? I played around with it a little and really got the pintail to pop out at you. I'm new to the digital world, too, so I might not being doing it right. This is by no means a slam at your photo, it's still a very good shot. I've been trying to take photos of song birds as they jump around on branches. It's hard. So you being able to capture a duck in motion; it's at the top of my to do list. I was just offering some CONSTRUCTIVE critism, what I thought would look nice, so please don't take offense. Then again maybe you posted exactly what you were going for and I'm just all wet.
