One of the advantages of being a dragonfly whisperer is that you have a pretty good idea what they're thinking. In particular, you often know where a dragonfly wants to perch. As a result, you can take a video of a particular branch or leaf and, before you know it, a dragonfly comes in for a landing.
Here's a case in point. In the following video, keep a look out for a male Blue Dasher who finds this particular leaf irresistible as a perch. He enters the frame from the right, rotates to the desired orientation, and then drops down for a landing. Nice maneuver.
