Caught this lady busy sorting out stuff for her nest from some old conifer roots. Rather overcast day but hope its sharp enough.

I wouldn't have expected such a long twig from a songbird's nest!! Good points by Randy, and I would add that I would perhaps crop a bit off the top, and to me there is a magenta cast to your image (bird and nest). You could open up your aperture a bit for additional SS and a slightly less defined BG.
