Why Birds Aren’t Birdbrained: Brains, Neurons, and Flexible Intelligence is episode 2 of Bird Lens, in Part 1, Chapter 1. Sheila and Victor begin with listening prerequisites and plain-language definitions, then trace the concept’s history, motivation, and evolution. Their conversation moves from foundations to deeper ideas through questions, corrections, an analogy, edge cases, practical observation tips, a fact, an anecdote, and a mnemonic. A challenging quiz runs through the episode without an early answer, and Sheila reveals the solution before a concise recap. The hosts close by previewing Why Scientists Underestimated Birds for So Long, inviting listeners to subscribe to and rate Bird Lens, and asking listeners to download the Bird Lens app.
