Getting a little ahead of the week’s story here but coming back yesterday, unaware of recent messages about PWD counts,  I paused at the Trucking Lane farmdam and snapped the flock in sections with a 300mm lens. Later I made non-overlapping sections and marked in red all the ducks that were NOT PWDs, the PWDs being  each given a white dot.  My count is 89.  Of course there might be more or less at any given time.  Before I snapped them I had flushed a small group from the road side which joined the flock on the far side.
