Jen - great shots. Just great. That last bird one is especially incredible. I've trying out bird photography since...well, today. All I got was a photo with a speck of a red-bellied woodpecker (posted to my Yahoo! photos accessible via the link in my sig line).

I like the way that the silt in the bottom of the waters in the LH photo makes such a pattern in the glassy water. BTW, is that snow on the bank?
