Regional Dialects Program Description In the previous program, we explored small local song dialects that became established in patches of chaparral habitat growing back after a forest fire. Larger regional song dialects can arise when populations of birds are isolated by distance or geological barriers. In this program, we listen to white-crowned sparrow dialects recorded by Chris Tenney: two from central coastal regions and one from the Sierra Nevadas, slowing down the songs to hear the dialects better. Program & Recording Notes Chris Tenney recorded the white crowned sparrows at Big Sur, Pebble Beach, and in the Sierra Nevadas. The Marin headlands post-wildfire white-crowned sparrow dialects are from CD accompanying Donald Kroodsma's book The Singing Life of Birds I slowed down the songs using Bias Peak. |
