Really how am I suppose to find a worm

Today started out below freezing so all the rain and the ice on the ground froze solid. It finally went above freezing in the afternoon and a bit of melting started. The birds are still trying to figure out how to find food. This robin found a tiny patch of exposed grass and tried to find a worm.

Good news it it is going up to 8C tomorrow and the melt will be on it will still be several days away from being totally gone come on spring!!
