It is clearly not spilonotus or collaris as you can see from the link, however, I don't think this picture shows enough to tell if it is any of the other subspecies. Do you know that it is one pure subspecies?
Edit: Just realised that you have to have a subscription to HBW Alive to view the illustrations of the subspecies.
Its a Village weaver male for sure but I also think you can't tell the subspecies from this picture. I'm also not sure if the captive population still is pure or if subspecies have been mixed-up.
