Wood anemone flowers early

A particularly pleasing sight in Spring is to see an abundance of wood anemones in flower. Now January should be far too early to see them but we were amazed to see one fully out yesterday (the 23rd). This location, right on the bank of the Tamar, is a good spot for both wild daffodils and wood anemones in Spring and a joy they are when in bloom but how come that just one anemone is doing its thing whereas there is no sign yet of any of its companions showing. Strange thing nature at times. It was pleasing on the way home to hear a mistle thrush singing. I find that wildlife can give enormous pleasure even with the more common species, and in any month as well.
