The vocal life of a songbird is similar to ours in many ways. (From 2011)
And this re-invention of language has been mirrored in the songbirds. An experiment from 2009 by Fehér and colleagues took newly hatched songbirds of the zebra finch species and raised them in sound proof chambers. They did this during their critical period of language development. Much like the Nicaraguan children, these birds were raised in a world without song. What happened next is quite surprising.
And a new study by Kentaro Abe and Dai Watanabe published in today’s issue of Nature provides strong evidence for this idea. They focused on a species of songbird called Bengalese finches. The researchers wanted to understand what sorts of songs these birds consider to be similar, and what are the features that make a song soundThe way the researchers went about doing this is downright ingenious. When a songbird hears a song sung by a member of its own species, it calls out in response.
