The Ontogeny of Vocal Learning in Songbirds and Its Neural Basis
Quick fact
Songbirds are one of only a few animal groups (including humans, whales, and some bats) that learn their vocalizations, and they do it in two phases: first memorizing a tutor's song and then practicing until they match it—much like human language acquisition.
Why this is interesting
You might think birds are born singing their species' tune. But a young songbird, like a human baby, goes through a babbling phase before it can produce a perfect song. How does the brain shepherd this journey from noise to melody?
