I had lots of all of those and never a problem with lilies! The cedar waxwings always came and cleaned up the holly berries and then went their separate ways to have families, some families were around but never a pest. Starlings are always a pest and the blackbirds just sing too loud (and too early for some). Maybe there is some problem with the normal food supply and they are starving. I only had major problems with the thrushes once when an unusually mild winter was followed by another round of winter and they demolished my ornamental corn seedlings. We ended up putting cracked corn out and when the weather got back to normal they disappeared into the woods like usual. And the quail would demolish my sunflower seedlings if I didn't cover them with netting when they first germinated. Starlings are always a problem. Lead poisoning is the only thing that works on them.
This is very troubling, remember Alfred Hitchcock's "the birds"? If the birds ever band together we are all in trouble.
