I didn't say that it was "just Predator-prey". But birds are definitely both, and exist in a web of predator-prey relationships. Therefore it is contingent upon the presenter to provide at least some evidence that this is a "runaway" situation - a "die-off" rather than the usual alternatives, which happen all the time as Exmoor states in his initial post on this thread. Instead we're shown a bunch of dead birds. That is followed by a chorus of webshits here providing subsequent "the sky is falling" lamentations, moaning and gnashing of teeth.
