BIRD'S EYE VIEW

Sitting in a tree cleaning my feathers, I see them in front of the main house. I get curious and watch from above. They start moving in a very strange way! What on earth are they doing...? Half of them running around trying to get into a circle formed by the other half. In stead of inviting them into the circle, the circle people block them. How unfriendly! Then they form pairs and start pushing each other. Is this an army training,I wonder. Now they're jumping up and down, shake their arms, make circles with their hips, stretch as far as they can. All very peculiar. If this continues I might consider to move to another tree....
