One of my favorite things to do is just sit back a little ways from the hive and watch the bees fly in with loads of pollen and nectar. The pollen can be seen on the hind legs (in the corbicula for the scientifically inclined) of the returning foragers. Right now the bees are bringing in light grayish pollen and bright orange pollen. The nectar is carried in the stomach of the bees and cannot be seen.
Thus far, the colony seems to be flourishing. Every week there are more and more bees flying about.
