With the temperature about 21 degrees F and a bright, late morning sun, I went out to the bee yard to give each hive a glance.
All three of the langstroth hives showed activity at the top entrances and, as usual, Lib-BEE-taria, with its population of Carniolan bees, was a bit grumpy at my inspection. Even in this temperature, I had one guard bee take a flight at my face, more as a bluff than an actual attempt to sting. While I do like seeing the bees alive in these hives, I do worry about them being at the top entrance. This could mean they have run out of food stores, and, while I did place fondant over the inner cover and under the quilt boxes last month, I don't know when it will be warm enough to place more fondant there. Around each langstroth, there is evidence that the bees have made cleansing flights. I hope none have nosema, a dysentary-like disease.
I saw no evidence of active bees at either of the top bar hives' entrances' but that could simply be because the winter cluster is not near the entrance that's opened. Each hive does show evidence of recent bee flights, however, so that is good.
