First song of Spring

Although several birds have been singing of late, especially the robin and song thrush, I was very surprised this morning to hear a greenfinch singing. It was not as if it was one of those lovely sunny January mornings as it is downcast with intermittent rain. Greenfinches will sing early in the year and I always wait to hear a chaffinch singing before I conclude that spring has truly arrived, but this is a particularly early instance.
