?? Researchers with @virginiaworkinglandscapes visit this bumblebee hive twice a month at the Smithsonian Conservation Biology Institute to sample pollen from bees and to survey the surrounding vegetation. They are measuring bee foraging efficiency, colony growth, and reproductive success – all factors that are important for predicting the long-term survival of bee populations. #PollinatorWeek
