Abandoned.  Our summer birds abandoned their house for warmer winter quarters back in the fall.  The temperatures have stayed stubbornly cold and we find when we walk in the mornings that most other walkers have abandoned the streets.   They are quiet and we have them to ourselves.   This morning even though it was only 3 degrees we are noticing more bird song.  Cardinals and blue jays are calling loudly to one another and give us hope that spring really will be coming.  We look forward to the sparrows moving back into the bird house and watching another cycle of new life.
