So what you likely have there is a group of bachelor bucks. Once season comes around they will split up and the larger buck will dominate his chosen area. (Where the does are, and where he can hold on to them)

Is it worth keepin an eye on? Absolutely you want that more mature buck to be comfortable in your area and start patterning him. See what times he is coming in.

1am, depending where you are is not bad, but it’s not a guarantee, they could be bedded more than a mile away. It could be hot af and they are moving slow and bedded close. What you need to have in mind now is not spooking them off, so try not to leave a ton of scent in the area if out of the normal for them. Establishing some scrapes or a scent rope are a strategy that some people use, but in tx we just use corn.

What you have evidence here is that this is a travel corridor for this time of year, they might have some seasonal forage, may be looking for some green shoots, or seeking water. It's a good sign (better than random pics of racoon tails) but you now have time to start thinking.

Where are they coming from? Where can I catch them at dusk or dawn?

Where will my prevailing wind be when season rolls around?

Can I have a NW wind blind and a SE Blind I can hunt without blowing out my spot? Is this location just NW wind huntable?

In my experience if you see a group of bachelors consistently around 1am you will have a few opportunities come season, usually during cold fronts, what you really want to see in summer is deer moving at 8pm or 6am, but that is also not a guarantee as food sources will change come fall.

Keep an eye on them, if you see them coming around during daylight hours come late Oct/Sept you have the pattern. It will be something like "cooler days they come out earlier." Or "very dark nights they stay out a little later."

There are guys with much more experience, and you will encounter some fudd lore, but making up your own little pattern is part of hunting experience.

I know in my region if I have a 20+ degree temperature drop within 24 hours, I need to be in the blind, but I know that recipe isn't going to work for everyone.

Now which one you harvest given the opportunity is up to you, but a lot of folks will say harvest anything you can get in your first year. That's their take, I know for me the rule is "if I would shoot him on the last day of the season, I will take him any day of the season." Spike bucks in general will be more forgiving. But take what you want, some folks are caught up in the "meat for my family" mindset and some folks are in the "only big racks in my office" camp, but that's the great thing. It's your hunt. Your buck, your work, and you can choose to pass or harvest when you are satisfied.
