For the birds that is.
You fly. Then you fly some more. And obviously that wasn't enough so you fly again. Be careful not to fly into the other 3-4 birds that are flying at the same time and keep going. Fly up, down, turn right, turn left, turn in a 180 degree angle and come back to where you started. Just keep flying.
15 to 20 minutes later, this will result in some very very tired birds who just plopped down wherever to take a nap.
