Thank you all for the nice comments. What is interesting about the first pic is that it was taken at ISO 2000 with the 7DII. What saved it here is that it was at very close range so I did not have to push the sharpness too much in post.
Very nice set of the little guys. I'm in Canada but have yet to see a Canada warbler. The 7D2 can handle the high ISOs if you don't have to crop much or push shadows at all. It looks good in that first shot.
