Bird intelligence depends on more than brain size. Sheila and Victor explore why densely packed neurons—especially in the pallium, an avian forebrain region—can give small brains substantial processing capacity. They examine why absolute and relative brain size are incomplete measures, and why development, experience, and ecological challenges also shape cognition. The episode follows New Caledonian crows’ repeatable pandanus-tool designs, including a survey documenting 5,550 tools across 21 sites, and considers evidence linking complex vocal learning with stronger problem-solving in some songbirds. Along the way, they offer practical guidance for observing flexibility without mistaking one dramatic behavior for a final verdict. Listen to Bird Lens, then visit birdlens.app for more episodes.
