Is the idea here that French falconers send their birds flying at absolutely everything? That they are quick to react and always ready to go?
I’m struck that it’s the falconer’s and not the falcons that are flying at anything they see.
So – he as the audience, as the patron to this performance, will send forth his falcon, the performers, with a great sense of readiness? Does he have an itchy trigger finger for shows?
He cannot hold back receiving a performance? This seems the most logical as the very next line is a request for a speech. And we, either a royal we, or a Hamlet, Rosencrantz, Guildenstern and Polonius we. Royal we seems more likely however.
