Another wonderful photo, Glenn – and the first one that I feel I can offer some constructive criticism for, since all the others have been perfect in every way!

The bird itself is perfect, it's the foreground I object to. I find that its brightness detracts from the bird and makes it into a full daylight scene rather than the dim evening typical of the species.Using a post-processing graduated mask/filter set to negative exposure will help to reduce the brilliance of the lichen-encrusted log/rock the whip-poor-will is on. My 2 cents worth (while pennies are still around).
