birdseye:Lyceel... amazing shot of the group of ducks flying...what did you set your camera at on this shot? i have chances for shots like this daily, and i never get it right...love to see photos like this, look just like what they looked like in the field. great job.
Thanks for the compliments, everyone. Here's the data:
Nikon D300, 70-300mm AF-S VR, f/8, 1/640", Aperture priority at -0.67 EV, matrix metering. Focal length was 300mm. If I remember correctly, I quickly switched to 51-point AF mode just as the ducks went airborne, and trusted the camera to get them in focus for me. It didn't let me down this time 
Picture was shot in JPEG Fine, cropped from 12 Mpx to 2250x1600, subtle sharpen applied, and I slightly warmed up the color balance (had the camera on Auto WB, which tends to go a bit cool for my taste). Finally, it was rescaled for posting.
