I've been looking at several parrot skulls and faces.
They seem to have some kind of 'cheek' surrounding the
mouth just behind the beak. In other birds, this part
is cheekless but possesses lips or some sort of horny
covering. Could this cheek-like structure be similar
to those interpreted for ornithischians? Is it muscle
or ligament or skin?...any ideas?

These structures aren't cheeks,they're called ''the cere.''They are functionally different from cheeks as well,as they serve as a joint between the skull and the unattached beak.It's the cere that allows parrots to be even more efficient eaters and processors of food then they allready are with their usually strong beaks,muscled and flexible tongue,intelligence and ''food-in-foot''-method.The cere means the parrot can move it's beak in a number of ways that go beyond what other birds can do.They certainly don't serve as cheeks however,as they aren't ment to store food in.
I hope that helps,
