Spring wildlife

From the gradual arrival of migrant birds to the unrolling of bluebell carpets - spring is a great unfolding story when everything seems possible (so writes Simon Barnes). In spring we have our beginnings. Life starts again: the early flowers daringly lift their heads above the earth and the birds burst into song. Spring is showtime, with the almost ridiculously sumptuous shag-pile carpets of bluebells and the deafening chorus at dawn.
