Just like humans have to learn to talk, songbirds aren't born singing.

They have to learn to carry a tune.

So in the beginning, they just babble.

Raisa DeBoer, a behavioral ecologist at the University of Antwerp in Belgium.

And they learn from a tutor, so they need an example song

in order to learn it. She says that example song might come from the chick's father, and over

time the baby bird tweaks that tweet to make it its own. And then it takes almost a year until

they're fully adult and until the next spring for the final song to come out.

DeBora and her colleagues investigated that song learning process in Canaries,

using two groups of baby birds.

The first consisted of inbred birds whose parents were siblings.

The second had parents that were unrelated.

And the researchers found that the songs of inbred birds...

...and those of the other outbred birds...

...sound pretty similar to the human ear.

I cannot tell the difference.
