WHOLE LOT OF RACKET GOING ON!

I put out the raven food yesterday morning and had no takers.  What in the world was going on?  I then went out on the deck to enjoy the nice weather and suddenly I heard it- raven racket.  Lots of noise and scolding and flying about.  There were 4 ravens in the valley.  Bold and Shy were not happy with the intruders and wanted them OUT- go away- get a new plan Stan- remove thyselves!!  This racket went on for sometime.  In the afternoon Bold and Shy returned to the redwood trees and got their food.  They were very quietly sitting on the tree branch as if nothing had transpired.  Peace in the valley had returned with Bold and Shy retaining their territory- banishing the upstart ravens!
