Low 50s again today. Activity in all the hives! #1 hive is by far the busiest, (the one with the dark, small bees) and seems to have had the fewest dead bees on the bottom board screen and landing board. #2 is the quietest, and judging by the evidence on the bottom board, the colony is very small. #3 and #4 have had the highest number of dead bees at the entrance and on the bottom board screen.
I saw a few bees bringing in pollen today. I wonder what they are finding. My heather is starting to bloom, but that's not a honey bee on it. Don't know what that is, I'll have to look it up.
