Helen Macdonald and Tim Dee will be at the shop to talk about birds, and about writing about birds. Radio producer Tim Dee propelled himself into the front rank of British nature writing in 2009 with his remarkable birdwatching memoir The Running Sky, followed in 2013 by Four Fields. Helen Macdonald, writer, poet, naturalist, conservationist, historian and some-time falconer, has recently published H is for Hawkwhich recounts how, under the literary tutelage of T.H. White and in part as a strategy for overcoming personal grief, she acquired and trained a goshawk of her own.
