RB Nuthatch

I took this today about an hour ago.  It's a dark and rainy day and I caught this Red Breasted Nuthatch on one of my perches before I was even able to turn my flash on.  This is as close to the limits of focus of my 600 mm telephoto so it is essentially full frame with some slight cropping off the left side to help with the composition.  So it is rather tight.  Even at F9, there is virtually no allowance for depth of field when one is this close.  I have 16 inch diameter domes over my feeders.  It is raining so hard right now (with some mixed in snow) that the birds are just hanging out under the domes to keep dry.

Iso-5000, 600 mm, F9, 500th, tripod, no flash, 80% of full frame with the cropping just on the left side, D 500, DxO Optics Pro, Adobe camera raw 10, Topaz adjust, TK sharpening action at 40%
