about a month ago, i discovered a nest above my kitchen door. i would leave fresh water, seeds and bread crumbs out each morning. probably enough for an army of sparrows. last friday, i peeked out of the window and saw a tiny fledgling on the stair being coached to fly. they're gone now. i really miss them. i'm thinking about removing the now vacant nest and putting the ceramic bird house I came across in its place. or maybe i should wait until next year. any suggestions?
