Summary
Birds do the darnedest things. They fly, of course. They sing. They hunt in pitch darkness. They hide their food and remember where they put it. They use tools and migrate over astonishingly vast distances—sometimes even sleeping while in flight. How do they do all this? What's going on in their brains that makes these and other remarkable behaviors possible? How did their evolutionary path mold them into the incredible creatures they are today? My guests today are Dr. Andrew Iwaniuk and Dr. Georg Striedter . Andrew is a comparative neuroscientist and Associate Professor at the University of Lethbridge in Canada. Georg is a Professor of Neurobiology and Behavior at the University of California, Irvine. Together they are the authors of the new book, Bird Brains and Behavior: A Synthesis (available open access here ). Here, Georg, Andrew, and I consider the deep history of birds—how they skirted the mass extinction event that felled the dinosaurs, and then radiated out into the 11,000 plus species we know today. We talk about how bird brains differ from those of mammals and reptiles—in terms of their size, but also in terms of their major structures, and in terms of their wrinkliness. We tour some of the most peculiar and perplexing bird behaviors, and consider their neural and anatomical underpinnings. Finally, we consider what we can learn from bird brains, not just about birds but about brains in general—how they evolve, how they get wired up, how they do and do not vary. Along the way we touch on barn owls, hummingbirds, megapodes, mallards, pigeons, parrots, starlings, and underestimated waterfowl; we touch on how birds' brains change with the seasons; the enduring mystery of magnetoreception; the possibility of olfactory maps; the optocollic reflex; the social inte…
