(I observed this behavior myself, last week)
Bees and Bird FeedersDuring the winter and early spring before the flowers are blooming, if temperatures reach 60 or above for a day or two, an interesting behavior takes place among populations of honeybees. Dozens, and occasionally hundreds of bees descend on backyard bird feeders filled with birdseed mixtures that contain millet, which, like pollen, is yellow. If people are able to view the bees up close, they report that the bees are continually moving the millet around with their front legs.
Bee experts believe that the warm temperatures trick the bees into leaving their hives to look for pollen. The bees search for pollen, which is also yellow, but, of course, none is available during the winter. They are attracted to the yellow millet and, believing that it’s pollen, use their front legs to try to maneuver the “pollen” into the pollen baskets on their hind legs.
There is no reason for concern, the bees will return to their hive when the temperature returns to normal and the birds will return to the feeder.
