Mo' Birds #2

[Lava Lamp]

Here are some more that I put in the viewfinder "bird" thread, but could use a critique. All taken with a D70 and Sigma 50-500, mostly at 500mm.

Okay Lava, I'm completely jealous here. The two birds in flight are really terrific.
My favorite of this bunch though is actually the photo of the ducks. I like the contrast of the green against their bodies, and I like even better the splash of yellowy-orange from the beaks, in a mostly green/brown picture.
