Bad environment makes birds good singers

China Daily | Updated: 2009-05-22 08:10

WASHINGTON: A hostile environment and inconsistent weather may explain why some birds become better singers than others, and also likely have superior learning and mating skills, a study said yesterday.

The research is based on a large-scale study of mockingbirds in different habitats carried out by researchers at the National Evolutionary Synthesis Center (NESCent) in Durham, North Carolina, the Cornell University Lab of Ornithology and McGill University.

"As environments become more variable or unpredictable, song displays become more elaborate," said Carlos Botero, a post-doctoral researcher at NESCent.
