Consider this possibility:
Human beings cram a large number of birds into a small environment to produce eggs or chicken dinners...
The birds in the wild could differentiate between EATING and ASSOCIATING.
In captivity in over-crammed circumstances; what if the birds, in order to survive, had to project among themselves an "imaginary bird" that they juggled amongst themselves?
To keep the information alive as to what a bird really is; they might create a "global bird"; a wild bird pattern that they keep alive among themselves?
What is "a virus"?
Looking at practical experience and a New Scientist article I get: a virus is an alternative communication system; a "chemistry set"; that is "an accomodation set". If you stay up all night and don't listen to your body you might find you are getting a virus: a system that allows your body to talk to itself when you're not paying sufficient attention to it.
In the wild; birds are free to associate WITHOUT feeding; and to FEED without associating.
A virus may appear among them in captivity in factory-like conditions; so as to help the birds AVOID JUMPING SPECIES.
TO KEEP THE BIRDS AS BIRDS.
Now: in the factory you get this "imaginary bird" pattern; keeping the true bird present even in adverse circumstances by a "pass the parcel" information exchange among all the birds (thanks to a helpful VIRUS).
What if some of the captive birds; that have now become conditioned to this situation, excape into the wild?
How would a wild bird make sense of a "quantum bird"? A bird that "seems to be missing something"?
The wild birds develop an alternative communication system to accomodate this strange bird? So that the wild birds don't get confused between food-source and association?
Do birds die of "bird flu"? Or does "bird flu" die of birds? Is there a limit: where bird flu and birds die togther; cancelling each other out so as to limit the confusion?
Migration of birds: birds migrate for reasons of feeding grounds?
Why is there a much more dangerous form of bird flu around, associated with migrating birds?
In migration; there is a natural connection between "associating with other birds" and "feeding".
A stronger virus is needed to ensure "association" and "feeding" are kept apart as concepts in the context of migration where they are occuring togther? A stronger virus is needed in the context of migration? A more mobile virus so as to keep the migrating bird population safe from losing track of what it means to be a bird?
General note: I don't know if the universe is as rigidly mathematical-logical as this essay suggests by the way. Something seems to be missing.
Bird flu is a solution in search of a problem?
It solves cramming of birds in environments which prevent them from being free to feed alone, or to be with other birds without feeding?
Wild birds encounter some of these factory birds: you get confusion? The wild birds trying to make sense of the factory-birds; end out "passing the parcel" of "bird flu" among themselves till enough of them have it to cause a "neutron star" pattern? That is: to neutralise the confusion by redistributing it?
Human involvement in bird-factories places humans in the path of this situation.
The new bird flu might target humans acting like birds? (Air passengers?) Sounds far fetched.
SOLUTION: a possible solution to bird flu is for humans to feed wild birds. Give them a taste of human intervention so when the virus turns up they don't pass it on to humans; the virus defuses.
Note: bovine tuberculosis: if farmers gave cattle places where there was no grass (so they can associate without food); and places with clumps of grass (so they could feed alone); would that solve this "problem"?
