The local birds again seemed convinced that spring has arrived with a Mistle Thrush singing loudly and continuously from the top of a tall conifer in Rosshall Park while at least three others quarrelled in the treetops (at one point dive-bombing the singing bird). Dunnock was a new singer for the year but the others (Blue Tit, Great Tit, Coal Tit, Goldcrest, Goldfinch, Greenfinch, Stock Dove, Robin, Woodpigeon and Starling) have all been singing for days if not weeks. Robin is an interesting case. At least some of the local birds have switched from their subdued winter song to a full-blooded and full volume spring song.
