In my neighborhood, once the leaves fall, nests are revealed: squirrel nests, bird nests, sometimes even a hornet nest or two. This is the first time I have seen a honeybee nest.
I guess this is how honeybees build hives when there is no beekeeper.
I tried doing some online research about these honeybee nests, but most of the hits were either about how to remove the nest (as in "pest control") or how the honeybee population is being decimated. Two ends of the spectrum.
