This is the kind of die-off that impressed Rachel Carson.  MIKE GOCHFELD

Unless the dead birds have been analysed for pesticide residues there's no
way of knowing if pesticides are involved.  I think if you went into any
suburban neighborhood, whether there were dead robins or not, you would find
a "history of spraying", so any "correlation" is meaningless.  Given the way
some people use lawn pesticides, I would not be surprised if pesticides
turned out to be the cause, but let's use good logical thinking here, rather
than simply blaming the "usual suspect".
