Hi,
I am afraid I was wrong concerning this Ringed Turtle Dove. I was
thinking about Streptopelia roseogrisea which is genuine "wild" species.
Whereas S. risoria is actually domesticated and bred form of
S.roseogrisea, with non-species status by some authors.
There are several "color" variations of Ringed TD, thus my discussion is
not very precise and concerning the genuine species S. roseogrisea.
Well, anyway I would like to see some wing photos and better photos of
all underside of that bird to be sure about ID.
More interesting notes about Ringed TD:

I just switched the Ringed Turtle-Dove photo to one without the tag obscuring
part of the tail - see http://www.duke.edu/~cwcook/museumbirds.html
You can more clearly see that both the undertail coverts and outer webs of
the retrices (tail feathers) are whitish. As I understand it, Eurasian
Collared-Dove is very similar to wild-type Ringed Turtle-Dove but has darker
gray undertail coverts and blackish outer webs, extending a little past the
black band on the inner webs.
