Gabbin' on a Sunday Morning.

          This morning I heard a conversation outside.  My knowledge of this morning is completely by sound, as the shades were closed and I was on the computer.  It sounded like two crows calling back and forth to each other.  The first one expressed a series of AHs.  The second one answered back.  The first one talked in a high pitch- possibly the highest pitch I've ever heard from a crow.    At least one time when a crow answered back, the AHs changed.  The first AH was higher followed by at least one lower pitched AH, possibly more. There appeared to be a few calling and answering sessions.  The conversation seems to be continuing but much further away now.
