The true nature of the much-maligned raven is almost as remarkable as the story of its recent recovery. These surprisingly intelligent birds mate for life, so their choice of partner is all the more important. In a unique forest on the edge of the stunning west coast of Anglesey in north Wales, the ravens gather each year to play the dating game. Newborough forest is home to one of the biggest raven roosts in Europe. Built to stabilise huge shifting sand dunes, this man-made habitat has proved a hit with the ravens. Onshore breezes rise up over the dunes, providing the perfect conditions for aerial acrobatics. The young ravens soon show that there is a fun side to their character as well.
