CT-based endocast reconstructions challenge the claim that dodos were uniquely unintelligent. Sheila and Victor examine intelligence as a spectrum shaped by ecology and specific tasks, not a single ranking. They discuss how the dodo’s brain size relative to body size fell within the pigeon range, while enlarged olfactory bulbs point to sensory specialization. The episode also explores New Caledonian crows’ manufacture of hooked twig and barbed pandanus-leaf tools for foraging, and western scrub-jays’ future-oriented food caching. Along the way, they explain why brain size, neuron counts, and impressive behaviors are clues rather than complete measures of intelligence—and why the better question is, “Smart at what?” Listen to Bird Lens and visit birdlens.app for more.
