“Louis Lefebvre, a professor emeritus of biology at McGill University who’s compiled a database of more than 4,400 innovative behaviors from nearly 1,700 avian species. And far from being a mere cataloger, Mr. Lefebvre uses this data in his fascinating book, A Bird’s IQ: Innovation, Intelligence, and Problem Solving in the Avian World, to examine some intriguing questions: ‘Are birds intelligent and, if so, does this intelligence resemble ours?’”
—Sam Kean, Wall Street Journal

"Lefebvre, who has spent decades conducting research on bird intelligence, argues that some brainy avians are remarkably similar in their cognitive capacity to primates such as ourselves."
—Nature

“This gem of a book is a must-read encyclopedia packed with the latest science and vivid storytelling.”
—Marc Bekoff, Psychology Today

"[A Bird's IQ] shares the tricks, inventions, and astonishing feats of birds around the world as it examines their intelligence. ... Bird lovers will find a lot to digest, while readers who are interested in animal intelligence will enjoy this new perspective on the topic."
—Library Journal

“Animal behaviorist Lefebvre pens a vivid book on avian intelligence…this lively look at the myriad ways birds have found to exploit their environment and find their food is full of fascinating science and engaging anecdotes.”
—Booklist, STARRED review

“Packed with enlightening case studies of avian ingenuity, this will make readers rethink the meaning of birdbrained.”
—Publishers Weekly

“With equal measures of joyful curiosity and scientific precision, A Bird’s IQ maps the capacity of birds for discovery, innovation and learning. You will never look at those featherheads in quite the same way again.”
—Candace Savage, author of Bird Brains

“A Bird’s IQ is an amazing avian adventure. It provides the reader with gorgeous glimpses into the mysteries and magic of bird brains and behavior, and in a way that integrates the author’s passion and academic knowledge of the field, both scientifically and artistically. Like a profound magic effect, there are hidden gems on every page, tailored to both the general public and the in-depth expert. A page turner!”
—Nicky Clayton, Fellow of the Royal Society and Professor of Comparative Cognition, University of Cambridge

"Lefebvre has a talent for distilling complicated research into digestible prose, even when discussing complex topics, such as how the level of NMDA 2B receptor expression relates to a species’ rate of innovation, making this book suitable for both casual birders and scientists alike.... A complete and informative book on bird intelligence."
—Kirkus Reviews

“This book is a gem, witty, entertaining, insightful, and deeply informative—a must-read for anyone interested in birds or brains. I learned something new on every page and came away with a more profound understanding of birds and wonder at their astonishing mental complexity and capacities.”
—Jennifer Ackerman, New York Times bestselling author of The Genius of Birds, What an Owl Knows, and The Bird Way
