I'm Karen Kwan.

That's a bird called the hermit warbler. It freeds along the US West Coast.

They all kind of look the same. They have a cute little yellow head and a gray body.

Typically, birds sing the same one song within one region because the song attracts mates.

And different regions can have slightly different dialects of the song.

But what we also notice that there are some places that more exceptions to this rule, that some places there is more than one song in the same place.

And so we were curious why that would be the case.

To investigate, Furnas and his team recorded Hermannier songs, lots of them.

We had to go all over California.

So we went to a hundred different locations throughout the state

and all the different potential habitats of the species. The researchers

analyze all the Hermit Orpler songs they collected and discovered that the hermit

orpler doesn't just violate the usual one song per region rule they

positively demolish it.

Doing this over a period of 10 years, we found actually an amazing 35 different dialects across the state.

Here are just two examples of dialects.
