someones been digging

 this dog was back again to investigate the digging

 this bird , a jay I think seems to be staring at the camera(you need to enlarge the picture to see)

 still ice on the bowls

 someone has been messing around here but I don't know who (I need another camera)

 the soil on the bridge is frozen solid so no tracks,I've spread some sand to see if theres any movement, an old trick reputably used localy  by jealous husbands to check if their wives were having visitors

this mushroom was nudged by an unappreciative visitor
