I seem to remember a number of similar reports of unexplained bird falls several years ago. The attempted explanation of a predator such as a sparrowhawk causing this is very unlikely. Sparrowhawks mode of hunting mostly entails flying low over the ground using cover to hide behind, then suddenly appearing and catching their prey by surprise. Other raptor species, such as, peregrine falcon - an ariel hunter - do take starlings, but for them to cause a mass crash landing like this does seems unlikely and so far as I am aware previously unheard of. A starling flock would stick close together in the air if there was no close cover nearby until one was picked off or the peregrine give up.
Could the deaths be attributed to the birds becoming suddenly aphyxiated due to flying into a pocket of dangerous gas, like methane, bubbling up from below the earths surface? Is this a possibility? Just speculating.
