bird call ID

Someone at my work has come to me asking
about a bird he has heard calling in his backyard the past few days. It
calls in the afternoon and sometimes mornings. Everything points to a Common
Koel.
However he looked at the COG Photo Gallery
and said it looked most like a Fan-tailed Cuckoo and not a Koel. However
when I played the Cuckoo's call to him he said it wasnt the right call.
The only sound file I could find for
the Koel was from a Hong Kong Bird website and he said it didnt sound exactly
like it.

His description of the call was (exact
words) :  "DOOOOOO-Weee ((DOOO is constant pitch) Wee  rapid
rise in pitch with rapid decent)"

He lives in Wanniassa. Has anyone else
heard a Koel or similar bird in Wanniassa recently? Are there still any
Koels around the suburbs?

Cheers
Marnix
