Urban beekeeping in New Mexico's largest city.
Unlike nectar foragers, pollen foragers take the pollen into the hive and deposit it into the cells themselves.
(Nectar foragers pass it onto a worker bee inside the hive. She will "chew" it for 20-30 minutes before depositing it into a cell.)
Here are two videos of workers returning loaded up with pollen and scraping it out of their pollen baskets - a top view, and a side view.
