A side-issue perhaps, but is it true that directed pecking "keeps the peck
aimed toward the target through corrective action"? I seem to remember
a Scientific American article in which it was shown that chicks who were
fitted with prism spectacles did not learn to compensate for the offset
between where they pecked and where the grain was. Is this now not believed
to be so? Or is it true only of chicks and not of other bird species or ages?
I didn't want to introduce THAT issue into the discussion. I was already
having enough trouble communicating the logic of the EAB explanation for
autoshaping without "going ballistic" and then having Bill do the same! (;->
