Program Content

Birds generally take a little minibreath between syllables when they're singing, up to 30 a second. But that's in some ways the least of the differences between their breathing and ours.

Sound Sources

The red-winged blackbird's and robin's songs are from the CD collection Bird Songs of California produced by the Cornell Laboratory of Ornithology. I slowed the robin's song using Bias Peak.

The Beatles "Blackbird" is from volume 1 of The White Album.
