Black Merlin in flight

For me, this is my favorite post so far basically because this is a wild black merlin (falco columbarius sucklei) that I had the pleasure to photograph as it plucked a dragonfly off a blade of grass in a marshy area in San Diego. I watched this bird as it sat on a high tree overlooking a large marsh. The first time I saw it. It flew like a bat out of hell out into the marsh and as I watched it go by I noticed it had an insect in its feet. It finished eating, so I placed myself inbetween the tree and the marsh and hoped he was still hungry. Ten minutes later, he did it again. He was so fast that I was lucky to get any shots at all. Thank God for the 1D. I only wish I could have gotten closer, this is about a 80 to 90% crop. But then again, I may not have been able to follow him with a bigger lens. Any photoshop tips to make this image better would be welcome. Thanks.
