Authors of The Lost Words are creating a new kind of field guide to celebrate the nearly 70 species of birds currently in severe decline in the UK.
Birds are disappearing from our lives and landscapes, says Jackie Morris, discussing her new collaboration with Robert Macfarlane, which seeks to celebrate and defend Britain's most threatened bird species.
Jackie Morris grew up in the Vale of Evesham, dreaming of becoming an artist and living by the sea. She studied at Hereford College of Arts and at Bath Academy, and went on to illustrate for the New Statesman, Independent and Guardian among many other publications. As a children's author and artist, she has created over forty books, including beloved classics such as Song of the Golden Hare, Tell Me A Dragon, East of the Sun, West of the Moon and The Wild Swans. She collaborated with Ted Hughes, and her books have sold more than a million copies worldwide. Jackie now lives in a cottage on the cliffs of Pembrokeshire, which she shares with a small pride of cats and various other gentle creatures.
