Cultures around the world have a siesta around 2:00 -- 3:00ish. Birds are quieter and less active at that time. Most deer are probably bedded. My chickens, my dogs (when I had them), everything that lives "in the moment" takes a rest in the mid afternoon. Half the time, while at work or hunting, I'll catch some Z's around 2:30 so that I'm rested to tackle the late afternoon & evening. Seems like a good time to either rest or settle in somewhere new. On the other hand, you may be among the noisiest thing out at that time so maybe your movement will be more conspicuous. Could work against you. It's a risk either way. Might as well do what you want and let fate decide.
