It's hot here for this time of the year. The temperature is getting into the upper 90's with little rain. This time of the year I give the bison a dose of the deworming medication fenbendazole mixed in molasses. I scoop the mixture out of the tractor's front end loader into several trays I have in the corral. Doing it in the corral is an added safety measure for me because I can block the corral gate with the tractor while I'm filling the trays in case the herd smells the molasses before I'm safety back on the tractor. If they don't smell the molasses while I'm loading the trays, I will then drive the tractor out into the fields looking for them. Once I find the herd I circle them once with the tractor and start driving back to the corral. At some point in the circle they pick up the scent of the residual molasses in the front end loader and start to follow. At first they follow slowly, but, as we get closer to the corral, they get more excited and start running. By the time we reach the corral the whole herd is at a gallop. They run right past the tractor into the corral where they start licking up the molasses with enthusiasm.
From my perch atop the tractor I get a chance to watch them during and after the occasion. 
And many of them like to take the chance to look at me. I imagine that to them I'm a very odd creature. I don't walk on four legs and I'm always doing things with objects (tools) or sitting on top of the tractor. I don't even eat grass. 
Wild blackberries are abundant this year and I can't help but take some time each day to eat them. I've never seen bison eating them. I suspect they would like blackberries, but their tongues are probably too large to get at the blackberries without getting thorns too.
