Tree Swallow

This is from the same morning session as the Band-tailed Pigeon I posted yesterday.  It's amazing what kind of colors these birds can turn depending on the angle and color of the light.  I think this is the bluest I've ever seen one.

1D4, 500mm f4 ISL + 2.0TC, Jobu Gimbal on Gitzo legs, f/8, 1/40 sec, iso 640, aperture priority, pattern metering.  Processed in LR5 & CS6.  I had too much lens for this, but wasn't about to try changing it at this point so I very carefully framed the bird to try to get it all in.  I just barely cleared the tail.  When I processed it, I played with it and finally tried adding canvas on the top, bottom and right.  It took a bit of playing to get the perch to work out, but I think it came out all right eventually.  Taken in my backyard at 4:45 AM on June 29, 2014.

Your comments and criticisms are welcome and appreciated.
