Some Birds Listen Instead of Look for Mates
December 2, 2009
Looks can be deceiving, but certain bird species have figured out that a voice can tell them most of what they need to know to find the right mate. Andrew DeWoody, a Purdue University associate professor of forestry and natural resources, found that the higher the pitch of a male bird's song, the more genetic diversity that bird has, making him a better mate for breeding.
