Published in 1953 with an introduction by the celebrated naturalist Brian Vesey-Fitzgerald, this authoritative volume presents a rigorous and compelling examination of animal migration, challenging prevailing scientific assumptions and arguing that the navigational feats of migratory creatures demand a far deeper explanation than contemporary biology had yet offered. Acworth chronicles the extraordinary journeys undertaken by species ranging from familiar garden birds to the iconic Monarch butterfly, marshalling evidence that unsettles easy answers and pushes the boundaries of natural inquiry.\n\nWritten with the conviction of a determined intellectual maverick, the work sits at a fascinating intersection of natural history, observational science, and philosophical provocation. Acworth's prose is precise yet accessible, drawing the lay reader into technical debates without sacrificing rigour, while the endorsement of Vesey-Fitzgerald lends the work considerable authority within mid-century British naturalist circles. A product of its era yet still thought-provoking today, this rare volume will appeal to collectors of vintage natural history as well as those captivated by the enduring question: how do creatures so small navigate a world so vast?\u003c\/p\u003e","brand":"Secondhand Stock","offers":[{"title":"Default Title","offer_id":49131000758491,"sku":"2026200009660-SECONDHAND","price":20.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0523\/7646\/9701\/files\/6a9c5e1d-294c-4c30-ad85-12ecb6c11f5c.png?v=1786594243","url":"https:\/\/bookgrocer.com\/products\/2026200009660-secondhand-bird-and-butterfly-mysteries-realities-of-migration","provider":"Book Grocer","version":"1.0","type":"link"}
