Some birds are relatively easy to study. Ross Crates studies the ones that aren't. He's part of the

difficult bird research group at the Australian National University. All our study species are

quite challenging to study for various reasons, mostly because they're really rare and highly

mobile. One of those difficult birds is the critically endangered Regent Honey-eater. They're

medium-sized songbirds, with bright yellow tails and black and white chests. And though they

once roamed Australia in flocks of hundreds, fewer than 300 remain in the wild today.

Crates and his team tracked the birds over a five-year period.

If they encountered a male, they'd record his song.

And they noted whether the males were paired up with females.

They found that a quarter of the birds sang variations of the traditional honey eater song.

And 12% of the birds weren't singing honey eater songs at all.

They were parroting different species songs, like this.

Or this one.

That could mean bad news for the bird's future, because males singing those untraditional
