Bird watching

One the strangest thing about bird watching is that at times you end up watching clumps of earth.  This morning I was walking through fields and scanning them for returning Red Wings and Fieldfare.   However, every time I thought I saw a bird I checked out the sighting with my binoculars and was frustrated to find all I had seen was some suspicious looking clump of earth.   I could argue that the visibility  was really quite low, it was, but the truth is that my eyes are not as good as they were and I was a little too optimistic.   Perhaps my neighbor is right - bird watchers are twitters - well at least this one.
