It's been almost a month since I posted anything here, so I wanted to catch up. I wrote an article about how I came to meet this particular rattlesnake under my shed in late November; most people found it pretty entertaining, if you're interested in reading it. https://theartfulengineer.com/the-rattlesnake-under-the-shed . Nikon Z7 with Nikkor AF-S 500mm f/5.6E PF at its minimum focus distance of about 10'.
I like the crop, Frances! It's interesting having the bird look back over its shoulder. It adds a little tension because the bird is standing facing right (so you want to put him on the left side) but looking left (so you really need to put him on the right side). Some might prefer that the picture not have the tension, but there are ten bazillion bird photos like that already, anyway.
