Feral is correct in North America because honeybees aren't native here.
There are native bees, though, and they're often much better pollinators.
Of course, they're also subject to habitat loss and aren't commercially

I don't think small beekeepers do much moving of hives.

True. Even in fairly developed areas there's plenty of flora to support a
few hives.

It's necessary for agriculture, not for the bees.

That implies that starvation isn't a factor in CCD. Nectar isn't that
different than sugar water, and worker bees only live a matter of weeks, so
a temporary fix is all that's needed.
