Spotting shots at the range this year is going to have a different twist. I picked up a Tridapter phone adapter for my spotting scope. It is a gadget that places a phone over the eyepiece and lines up the phone's camera lens with the spotting scope's lens. Once setup you can see the target on the phone's screen at a glance, a nice convenience that also allows pictures to be taken. This gizmo will work out great I think.

I was in the path of totality for an eclipse in 2017 - it was definitely not 100% dark, but very dusk-like. Birds quit chirping, night-time insects started making their noises, etc. It was a cool experience.
I think it will happen to fast for any animal to really fully react to it. I am sure they will be confused just not sure how much their daily pattern will change.
I doubt they will. Possible though. They might say be out in a field and notice it getting dark and start heading towards their roost but then daylight come back pronto. Or jump up in a tree at brush whenever they stand if possible. Will freak them out without a doubt. The last think they like is standing on the ground in the dark.
