Some Songbirds Have Brains Specially Designed to Find Mates for Life.
'If Cupid wanted to make two songbirds fall in love, hed have better luck aiming at their brains. Thats because songbirds, which form lifelong mating pairs, have brain systems perfectly tuned to fit together.
While you sort through the messages of admirers, deciding who to make your Valentine, consider finches.
Young males in this family of feathered crooners learn the song of their father, perfect it and perform it as adults to attract a lifelong mate. Its loud, elaborate and precise. With their songs they say chirp, chirp my brain is healthy, and my body is strong. Thats something youre into, right?
A female finch also learns the songs of her father from a young age, but she doesnt perform. Shes the critic. She analyzes every detail of a potential mates song, compares it to her fathers example and decides if this performer is one shed like to keep around. If she detects a song is too simple or off in any way, shell have nothing to do with its performer. Shes very picky, as she should be, because the mate she chooses will help raise their young till death do they part.
Over the past decade, researchers looking into the chickpea-sized brains of finches have discovered that each sex uses whats called its sound control system to convert sound waves to social messages and then use them to find mates, kind of how humans use vocal sounds to communicate. And while these systems are well-developed and finely tuned in both sexes of songbirds, the wiring is different.
The biggest difference between male and female brains of the same species is found in songbirds, said Sarah Woolley, a neuroscientist who studies finches at Columbia Universitys Zuckerman Institute.'>>>
