Very interesting thought. It's a little confusing, though, to
figure out in this circumstance who's doing the dominating and
who's doing the submission.
Since food begging is only done by juveniles and females,
wouldn't that be more likely to be the submissive behavior?
Making yourself look smaller and weaker-- in this case by
hunching down and letting your wings droop-- is the way
submissive critters demonstrate to potential aggressors of the
same species that they are no threat.
Your implication is surely right that it's the Bluejay's behavior
that is, um, inventive, where the WP is pretty much responding
