Paperback. Condizione: New. Print on Demand. This book examines evidence that birds possess color vision and the extent of their visual capability. Early work, largely dismissed as scientifically unsound, is reviewed and the author explains the efforts taken to define more rigorous experimental procedures. Through these, the author demonstrates that birds have a keener sensitivity to variations in wavelength than humans and may perceive divisions within the light spectrum that humans cannot. The author's findings suggest that color vision in birds developed as a response to sexual selection and organic necessity, and that their refined visual abilities played a key role in facilitating mate selection, nest construction, and predator avoidance. This book is significant for its decisive experimental evidence that birds are not color blind but enjoy a complex and nuanced visual experience.
