Can you detach a wing, flatten it and photograph it against a white background? That will help to confirm the family.

Tony, despite I partly destroyed the wing while preparation, I hope this will be helpful:

That does look like a sarcophagid wing. It's difficult to say precisely why the flies were breeding there, but
Helicophagella melanura has been recorded as causing myiasis in birds; and other species (especially
Parasarcophaga) are known to feed on carrion. It would be worth searching for a male to make a positive identification of the species - even if none has emerged, it may be possible to dissect a pharate male from one of the puparia.

Oh! I think that among bird nest material in nest-box there is a lot of different type of food to consume for sarcophagids: dead nestlings, dead parts of its prey, pupae of other dipterans to parasite or soft larvae of other insects to hunt: tineids, coleoptera, calliphorids. Thank You very much for Your help in identification and comments!
