I know that there might be robins in the woods that I just never see. But why don't I see any robins. I see lots of birds including chickadees, cardinals, and blue jays. There are Hawthorn trees out front where birds often go during the winter and there are worms in the woods. Robins love these. There is also mud in the woods and grass out front for a robin to make its nest. Sometimes during the spring I see grass and flowers in certain parts of the woods.
In case you want to know I live in central ohio. I have seen robins further north in grassy areas. but never here in central ohio.
