A brown thrasher knows a thousand songs. A wood thrush can sing two pitches at once. A mockingbird can match the sounds around it — including car alarms. These are just a few of the 4,000 species of songbirds. How do these birds learn songs? How do they know to mimic the songs of their own species? Are they born knowing how to sing? Partha P. Mitra illuminates the beautiful world of birdsong.
