Hello Marcia,
One possibly is that it has molted a large wing feather. We have heard this very noticeable and different than usual sound each year and found it to to be a missing wing. It always surprises me when I first hear it.
We have several Anna’s year around at our feeders. They are currently also feeding on sap from fresh Sapsucker wells on our birch tree, beginning eight days ago.
