There were reports a couple of years ago that some trees, when
attacked by insects, released chemicals that caused nearby trees of
the same species to increase the tannin content of their leaves, thus
rendering the leaves less digestible by the insects.  Maybe there's a
similar mechanism in effect to synchronize flowering?
