I'm definitely NOT addicted, but I have been known to spend A LOT of time at Bee-eater holes trying to get an in-flight photo w/ an insect in its beak.
My SO is the "look out" whose job it is to yell "INCOMING" when one of them is approaching the hole (I have my eye glued to the camera, focused on the hole, so I don't know when they are successful at hunting).
Of course, every car stops and asks what we see. My SO used to answer "Bee-eaters!!" in an upbeat proud tone.
But after more than a few grimaces, shakes of the head, and eye rolling, he now just says in a dejected shameful tone, "Just Bee-eaters..."
Put the camera on a bean bag so it can pointed at the hole without constant monitoring.
Focus on the hole then switch to manual focus. If the camera moves slightly, it will still be focused on the hole.
You can then look around as much as you like and judge for yourself when there is an incoming bird and hit the shutter release at the appropriate time.
Hunting cannot be considered a sport as all contestants in a sport should know they are playing the game!
I do put the camera on an "improvised" bean bag and use a remote switch, but they are so darned FAST once they fly to the hole, they are inside and out of sight in a matter of a second or two! I did manage some that I'm pretty satisfied with, but it's fun even when they don't cooperate fully.
