On returning from the MOS gull trip this afternoon I heard a raven croaking as I got out of the car.  I went round to the back of the house and saw it perched on a cedar that is on the border of our yard and our neighbors.  It flew off, came back and then pulled something to eat off the tree before flying off again.  Nice to get it as a proper yard bird rather than a distant flyover.
