Over the past few days honeybees have invaded our bird feeders. Why?
Although the bees are active, there are very few flowers this early in the season. The bees are not eating the seeds. They can't because their mouths are not adapted for seed eating. Instead, they are eating the dust that covers the seeds. That dust is mostly made up of tiny bits of seeds, small enough for the bees to eat. The bird feeders give them an easy feast until more flowers open.
