A raven’s small brain can contain primate-like numbers of forebrain neurons. In Bird Lens season one, episode four, Sheila and Victor unpack why “birdbrained” is a misleading label. You’ll learn: brain size alone cannot predict mental capacity; neuron number, placement, connectivity, and energy use matter. Parrots and songbirds can pack about twice as many neurons as primate brains of the same mass. Pigeon neurons use roughly three times less glucose per neuron than the mammalian average, suggesting an efficient energy budget. Avian pallial circuits support sophisticated processing without a mammalian six-layered neocortex. Crow perception, zero-like quantity representations, and New Caledonian crow tool crafting provide neural and behavioral evidence of flexible minds. Listen to Bird Lens and visit birdlens.app.
