When we inspect our hives, we always make sure to check the bottom board (the removable hive floor). A skilled beekeeper can get a lot of information about the hive just from “reading” the bottom board: How active is the colony? How many new bees are being born? Is there a parasite problem? What have the bees been feeding on?
Some of the pollen carried back by bees accumulates on the bottom board. Urban bees have a varied diet of pollen and nectar from many different sources, so the accumulated pollen comes in a variety of colours. The bottom board this week is looking absolutely gorgeous: we found yellow, orange, green, and even maroon and lilac-coloured pollen!
