Andrew,
I didn't have time to respond in full this morning when I thanked you
online. There is another possibility about the isolated calls of the Koel,
and that is that at first you might perhaps be hearing Koels still on
passage - they might move on from your area to points further south, and
you might be hearing the calls of several birds over a period of time
during migration. I don't know where the migration route is most dense, but
your area might lie along it. Just a thought. Your theory might also have
merit.
