A BIRD’S IQ

Surveying a wide variety of birds, including crows, finches, tits, and parrots, Louis Lefebvre, a world-renowned expert in animal behaviour, describes the remarkable innovations and problem-solving abilities of species often dismissed as ‘featherbrains’. From crows using cars as nutcrackers to cockatoos crafting tools, Lefebvre reveals how birds exhibit creativity, social learning, and even cultural transmission – traits once thought to be exclusive to humans and other primates. Blending his decades of scientific research with engaging anecdotes, Lefebvre examines the evolutionary forces that have shaped avian intelligence. He explores how birds adapt to urban environments, innovate in response to challenges, and pass down knowledge across generations. This goldmine of bird behaviour yields an ‘innovation quotient’ widely used by researchers to measure and rank how innovative a bird species is.
