My bees in September

Here are 4 of my 5 honeybee colonies in late September on a nice sunny day. I also have one more large hive down the road not shown here.
These are two full sized hives and two 5-frame nucs (baby hives). I am hoping to bundle the two little nucs together and attempt to overwinter them.
It was quite a busy day for them, all in a mad rush bringing in nectar and pollen. Our area is in the midst of goldenrod bloom right now.
