I wonder if video would be more useful data.  We're not very good at
processing sound (in general) compared with video.  No doubt you could
train an expert system ("deep learning" or whatever we call this flavor of
AI these days) how to detect bees from a video stream.  Instead of guessing
at the number of bees from a phased array of microphones for distances of
sound sources and cumulative intensity, it could count.  We might be able
to mine these streams for other insight we might not have otherwise had a
preconceived test.  ex:  it might be interesting to see what other insects
are detected when bees are either plentiful or scarce.  (or for a better
example, imagine something else we didn't think of then also remove it from
the set of all possible things that might be relevant but unknown.)

To further nerdify this setup we have to include some way to gamify the
data with crowdsource interaction.  I imagine some sort of "bee keeping"
analogy where the gamer is tasked with tracking/tagging the activity of
visible bees across the spectrum of howevermany camera feeds we have per
location.  Leaderboard plus achievement/badges should be enough competition
to keep eyes-on for at least a while.  There might exist opportunities to
monetize by selling virtual billboard space in a foraging field overlay:
advertisers pay a fixed price to get on the board, then pay additional for
each bee that cross their adspace with the premise that our beekeepers are
actively tracking the bees through those overlays.  "hive mind" + "mind
share" = "hive mind share"    I guess the next step would be AR/VR so
everyone can experience full immersion into both the bee problem and bee

ok, so there's some ideas... feel free to implement.  :p
