Sinister

I thought that this shot of a wet Common Grackle preening, with its nictitating membrane covering the eyes made a sinister-looking image.  To reinforce that dark feeling, I converted to black and white in Nik Silver Efex Pro 2, adding high structure and some extra film grain.  I reduced the opacity of the B&W layer to 85% to bring back a hint of color, and did local curves adjustments to complete the effect.
