Apart from a brief snow shower a few days ago when we had a little snow on the ground, we have had a very mild winter so far. Most spring flowers, and blossom, are out early. We even saw a few daffodils out in late November, which is very early for here.
It would not surprise me if some of the bird migrants arrive back earlier than usual unless we suddenly get a very cold spell. As they say, "n'er cast a clout 'til the May is out". March could be extremely cold.
