Today Kandace Glanville, an OSU Forestry Fisheries & Wildlife major and student assistant in the Borror Laboratory of Bioacoustics, talks with Angelika Nelson, Curator of the Borror Lab, about a recent research publication in the journal Ethology. The study is entitled “High levels of gene flow among song dialect populations of the Puget Sound white-crowned sparrow”.

Find out why we studied the White-crowned Sparrow Zonotrichia leucophrys pugetensis to investigate gene flow among song dialects:
The research aimed to investigate a correlation between behavioral and genetic differentiation:
Our research built on knowledge from previous studies and used samples that were collected previously:
We found gene flow among bird populations that differ in song dialects; this may demonstrate dispersal of young birds across dialect borders:

This is a really interesting study. I love the “blog” version interview format. A similar conclusion is reached in a recent review of song learning and geographic variation in parrots which, like songbirds, learn their songs. The study by Timothy Wright & Christine Dahlin published in Emu – Austral Ornithology this year concludes that there isn’t much evidence to link vocal dialects in populations of parrots to genetic differentiation among them.
Rich, thank you for pointing out the recent study on parrots: Wright, T. F., & Dahlin, C. R. (2017). Vocal dialects in parrots: patterns and processes of cultural evolution. Emu-Austral Ornithology, 1-17. http://www.tandfonline.com/doi/abs/10.1080/01584197.2017.1379356
Their study is also a great example for the use of recordings from sound libraries like the Borror lab for scientific research!
Fascinating article on gene flow among song dialects! It’s incredible how scientific research sheds light on the intricacies of nature.
