The bees have been flying on nice days (over 45 degrees with the sun shining) since January. They are primarily still in their clusters around the queen to keep her warm, but I suspect the if the queen hasn't already started laying eggs, she will next week. The bees gather the cedar pollen and the elm and pine pollen that has been making us all miserable and store it in their hive until it is needed later for food. With the trees and plants starting to bud and blossom, the bees will be out gathering nectar as well. Their numbers are not built up well yet after the cold weather, but last year when we had much warmer weather throughout February, we were catching swarms in March and April - and those usually occur when the bees outgrow their space for raising brood and/or storing honey.
