That's the call of the Hawaiian crow.

It's a critically endangered species, now extinct in the wild, after decades of habitat loss, persecution by farmers, and invasive diseases.

In the mid-1990s, wildlife biologists rounded up the few surviving crows and put them into a captive breeding program.

Today, Hawaiians can once again hear the calls of more than 100 Hawaiian crows, or

Al-A as they are called there, but only in aviaries.

Researchers once focused their efforts primarily on breeding and husbandry, but now they

need to know more.

And now that, you know, they're doing so well and it's at the point where, you know,

that they could be in the wild again, that now we can look at, you know, their vocalizations

and their behaviors and things like that.

Those other aspects, culture, if you will, are critical for a species as socially complex as the Al-Lala.

Tanamoto and her team made recordings of captive-bred al-a-la-pairs at the Keahoe

Hohohobird Conservation Center in volcano Hawaii,

and compared them to recordings made in the early 1990s by fish and wildlife service biologists of
