When winter days turn warm enough for honeybees to leave their hives, I find my girls in unusual places around my garden.
Bees make honey for winter food but if the temperatures are warm enough, they forage for pollen. My girls look for pollen wherever they can find it, especially in bird feeders.
I make my own bird seed combination including cracked corn for doves and other ground feeding birds. Apparently honeybees can find pollen in cracked corn, or at least they try hard looking for some!
