Red-tailed Hawk vs. Northern Mockingbird

EOS-1D Mk III, 500mm f/4 + 1.4x II, 1/1600, f/5.6, ISO 800
About 50% of Full Frame

Photographed last week from the beach at the North Point Natural Area in Morro Bay, CA.

I was watching the hawk, hoping for it to take flight, when the Mockingbird began harassing it.
The hawk did not seem to be at all bothered. This was the only frame where the hawk was
even looking in the direction of the Mockingbird.
Unfortunately, it was far away, at a steep angle, and on an ugly perch, but I found it amusing
and was impressed by the way that the hawk dwarfs the relatively large songbird.

Looking forward to your comments and critiques !

Great job capturing natures neat moments! This isn't an image to judge BGs, perches and/or all that other jazz, thanks for sharing.

Great interaction captured. Makes you wonder what is going on in the red-tail's mind. :) Thanks for sharing!
