Over the years I have seen several Mapgies with injuries to their beaks.
Usually this is an upper mandible completely broken off at the base.

1. How do they do this?

2. What happens, does the beak regrow, can they survive? The ones I have
seen haven't seemed to be starving, and one I observed for a few weeks and
it didn't decline during that time.
