Chris,
What a lucky fellow. Is that water near you. Just beautiful. And as for composition, the untidy left edge actually works fine! I would go over the edges and get rid of the sharpening, (or over-compressed jpg), halo.

Thanks, Asher. It compressed oddly...but then I did change the way I sharpened on this one so may go back an iteration and redo. The full file .tiff is perfect. The water is about 80 feet outside my back gate.
I had to leave the left edge like that or the balance would have been awkward. Birds rarely situate themselves in a perfect pose or habitat..sometimes it really takes some work.

Chris,
When I sharpen I do it on a duplicate layer and mask it, only allowing to show the inner portions while the sharpened edges get wiped with a 50% soft brush and that usually tames that halo. Also I always leave the picture and do something else and then try to decrease the contribution of any processed layer by anything from 3 tp 93 percent. I feel that blending in of even a tiny proportion of the original is best.
Still, if you sharpen according the protocols of Bart Van Der Wolf or Nicolas Claris, you won't have any halos to worry about!

Chris, Asher,
There are no sharpening rules set in concrete, but there are a few recommendations that almost always deliver good results.
One of the principles is that one shouldn't over-sharpen (use a smaller radius instead), because that will lead to halo artifacts. Another one is that high contrast edges that already look sharp, require less sharpening.
Both of these principles can be satisfied by using a sharpening layer in Photoshop, with a luminosity blend-if layer. It will prevent halo clipping especially around high contrast edges, so you can boost the sharpening amount for lower contrast micro-detail. The following settings are a good starting point:
I use a Photoshop action that duplicates a layer, sets the layer blending mode as indicated above, and calls my preferred sharpening plugin (FocusMagic), although the Photoshop a Smart Sharpening filter can also be used. That produces a sharpening layer that can be masked, its overall opacity can be reduced, or it can be switched off when the image needs to be resampled to a different size. Lots of flexibility.
Cheers,
Bart

It's not as bad and I may have to go back to the original file to get all the haloing out. Interesting way to sharpen, though. Thanks for the tip.

Saw several of these fishing as I was running around the Charles River yesterday. Just the head and neck would appear out of the water, look around, and down they went again.
