This is the song of a brown threshing machine.

This is a song sung by a brown thrasher. But that’s just one of the thousand or more that it knows, and it’s not the only avian virtuoso. A wood thrush can sing two pitches at once. A mockingbird can match the sounds around it, including car alarms. And the Australian superb lyrebird has an incredible, elaborate song and dance ritual. These are just a few of the 4,000 species of songbirds.
