Mono Monday-f8 and be there

I don't use f8 to shoot my birds......but I was happy with how this turned out, so I may try it more often!  The blackbird flitted in and flitted out again, so it really was a quick capture.
This is taken on a greyish morning with the background far away, and through a double glass window.
Thank you to SkiMe for an interesting mono exercise!
