Today is a Spring-like day in SE Pennsylvania.  So, here's a robin without snow in the scene. For many of my walks I'm using a Nikon D7100 with a Nikon 200-500mm f5.6.  It is a fair amount of weight to carry on a walk.  The images I'm capturing are hand held.  I'm pleased with the sharpness at this range about 15-20 feet.

During the winter several birds visited our feeder that overlooks a valley.  The natural result is that the background is plain, almost the same effect as if they were in front of a gray screen.  To compensate, I created a composite of two images from the same vantage point giving a more interesting background.  An oil painting filter from Photoshop was added - just for fun.
