I'm having real difficulties identifying this bird - I haven't seen it but I've been hearing it for years where I live.
I live in Haaltert, Belgium - in a rural environment (or at least as rural as one can get in Flanders, probably "suburban" anywhere else). About 200m behind my house there's a small brook surrounded by a humid wood and some fishing ponds. Lots of small wildlife there, including the bird whose sound I recorded here:

It's a bit hard to hear, and last week I managed to record it a bit more clearly (and I used some noise-suppresion to get rid of a mechanical hum)

The bird was definitely in the little wood, quite high up in the trees.
I've been listening to many Belgian bird calls but I haven't found anything that resembles it (even vaguely) - I've had suggestions of Golden Oriole (Oriolus oriolus) and European turtle dove (Streptopelia turtur) though I really don't think either fits.
The sound can IMHO best be described as a kind of "tee-rooo" sound, and it's very distinct and repeating, there's no significant variation.
So if anyone has a clue, or has an idea where I might ask?
