Whilst I walked out in a Summer’s rain shower, the sky seemed to fill with Rooks. These were not your normal Rooks following their slow, purposeful flight lines from roost to feeding ground, or back again. These were young Rooks. Their flight was erratic, directionless, fast and with no stable height. The purpose seemed to be one of pure enjoyment. The thrill of a new skill. Can Rooks joy-ride? These ones appeared to be doing so. Small groups and pairs wheeled round the sky in a sort of Rook circus until normal business seemed to resume once more.
