I have been reading a book about songbirds and it has made me think about
attention.
Songbirds basically can’t do shit to stay alive
except know what’s going on. So they get good at it.
They each have territories which they return to
again and again. The territories of different species overlap because they feed
on different things in different ways. They sing boundaries, they have
companion calls, which is one bird talking gently and continually to its mate
when they are out of sight. This is a negative alarm, it goes off when the
signal stops, that’s when they know something’s wrong. And there are various
male aggression calls and so on but the thing that concerns us here is the
alarms.
Birds listen to each other all the time. Other
species listen too, they use the birds as an early warning system. They birds
themselves don’t just listen to their own species, they know the patterns and
alarms for every nearby bird. They all sing-semi continuously and they listen
to each other. So the aural landscape of a forest is a web of mutually
reinforcing signals. When one bird gives an alarm the others will know why and
they will repeat and reinforce the signal. The signals have measurable shapes.
If it’s a multi-species alarm, ie squirrels and chipmunks too, you know it’s a
big deal.
Bird Plow – This is the big one. Usually
caused by humans. This shows the presence of an unconcerned alien, abrupt,
heedless and uncaring. We don’t kill many birds but they freak the fuck out
when we go in there. Birds explode in every direction away from the point of
entry, setting of sympathetic alarms from other birds, who then set off more
alarms and so on. So an experienced tracker can see someone approaching two
minutes before they come into sight by watching the birds.
Sentinel – The birds fly up to a vantage
point, rank up and keep watch like guardsmen. If an alarm is spreading through
the forest, it will stop at the sentinel line. This is one of a variety of
factors designed to make sure alarms don’t just go on forever, spreading and
combining. Birds a few feet away from a sentinel line will carry on as normal.
Can be for unidentified threats, a form of containment.
Hook – If you spend fucking ages getting
your body language right and familiarising yourself with the local forests, you
can sometimes persuade birds to ‘hook’ instead of creating a bird plow. This is
the alarm for a known predator like a local cat. The bird flys out of its perch
away from you then ‘hooks’ back into the edge of its territory, just out of
your expected reach. They will never move further than they need to, so you
could estimate the leaping distance of a predator by the birds movements around
it.
Popcorn – Popcorn is a series of hooks
moving along the line of a threats advance as it goes through the forest. The
birds ‘pop’ up in a line and circle back. The interesting thing about this is
that you can tell there is a ground disturbance moving at a fast controlled
pace. If it was accelerating and slowing down, that would be a different alarm.
If it’s a person they have a calm, controlled demeanour, of they would have set
off a bird plow. If it’s a predator you know it’s moving and not hunting. And
you never need to see the cause, just the signal.
Umbrella – This is a dome of birds, facing
towards the centre of the dome. This is for egg stealers, nest robbers,
sometimes for dangerous predators that have just eaten so the threat level is
down. Some birds dive-bomb the threat. If it moves it moves slower than a
popcorn signal. The dome traces the threat.
Weasel – This is a good one. Weasels move
much more randomly than other predators. They deliberately loop back, take
strange paths, freeze for long purposeless periods. The alarm shaped by a
weasel is shapeless and unfocused as the creatures disappears and re-appears.
The birds can’t find it. That shapes their response and that’s how you know
it’s a weasel.
These are the basic ones. The Bullet, the Ditch
and the Hawk Drop are all forms of individual movement which can tell you the
nature of a predator. Hawks that hunt in mid-air cause songbirds to drop a few
meters down into the canopy and then carry on. Hawks that hunt in the forest
are much more dangerous and provoke bullet and ditch evasion manoeuvres.
The Safety Barrier is a really elegant one.
In this case you think the birds are feeding unusually close to you. In fact
there is a more specific predator in the area and birds are using you as a kind
of cover.
And finally the Zone of Silence. Hawks fly
in silence, mainly because every bird around them shuts up when they are
around. The size and shape and depth of the arrow if silence heading into the
woods can tell you the size, threat and speed of the predator. And it cycles
upwards, when the eagle fly’s past you can see the haws performing songbird manoeuvres
to get out of the way. When you walk in the woods you probably carry a zone of
silence with you. It’s a negative space. The nature of the absence tells you
what causes it.
So why have I been thinking about this stuff?
Firstly I was thinking about druids and rangers.
This is the kind of stuff they should know about and wouldn’t it be cool if you
could model it in a game. But that requires the person playing the druid to
continually ask the right questions and for the DM to give the right answers. Which
is hard, and doesn’t scale across multiple gaming groups.
But maybe there is a way to cheat. Because the DM
is the world we can invert the pattern of attention and turn it into a pattern
of creation. Instead of imagining a bunch of orcs tramping through a forest and
carefully modelling the shape of the bird plow they would create, we turn the
process inside out. We could, perhaps use these patterns of attention to
produce the effect they usually warn about.
I was thinking something like this.

So two d8, one down, one across. I am not sure
about what to put in the top row, but HD is already a pretty good abstract
measure of threat right?
So, test roll, a 4hd monster generating a Popcorn
alarm. Popcorn is always something familiar and
not-currently-dangerously-active, so this is its habitat. That infers something
natural But if we take into account a fantasy world with a fantasy forest, that
could mean anything. A local ogre? Not dangerous, so probably just hunted some
people. And it didn’t hunt the people here because no bird plow. Hunting kills
create a lot of alarm.
The weasel alarm is good because all the freaky
things like doppelgangers and displacer beasts can go in there.
So all you need to tell the druid is ‘you
recognise a popcorn alarm about 50 meters away, its something much larger than
you, moving in this direction at a steady pace, and it live here, or moves
through here a lot’
To fill in the whole thing you would need to know
a lot about D&D monsters. Maybe you wouldn’t want to fill it all in in
order to leave fluidity. It also gets a bit mad towards the high HD monsters,
but there are high HD birds in the monster manual that could give alarms. Does
an eagle pulling hawk-drop like a songbird mean a dragon is overhead. And how
big is a dragons zone of silence? 10-20 miles?
Once you understand a pattern of attention in the
natural world, you should be able to abstract it, invert it, and turn it into a
kind of unique generator, creating the things it was made to describe. I wonder
if you could do it for other systems of nature?
