Actually, looking at the video, if you can’t get a net up high, but you can lure him consistently onto a shelf. Look at his preferred flight off of the shelf, set up a net in that flight path, and next time he lands, stand opposite of the net and stomp, clap, shout, and thrust something at him, preferably thrust something high to keep his flight pattern low and horizontal. Do it suddenly once he’s comfortable. He can see nets, but may panic enough to fly directly away from you into the net.
