BirdNote's Mary McCann describes an interaction with a Southern Cassowary, a huge, flightless, and almost-prehistoric looking bird. Found in the forests of Northern Australia, it has the lowest-pitched birdcall in the world.

Transcript

DOERING: Time to head “down under” to the lush forests of Northeastern Australia. They’re home to one of the largest and most unusual birds in the world, as BirdNote’s Mary McCann explains.

Encounter with a Cassowary

[Cassowary “coughing” calls]
That coughing sound is the call of a Southern Cassowary. It’s a huge, flightless, prehistoric-looking bird, found in the tropical forests of Northeastern Australia, New Guinea and Indonesia.
This bird would look right at home in Jurassic Park. It weighs about 150 pounds and stands nearly six feet tall with a striking bony crest. Its head and long neck are a deep blue... bare and featherless. It looks a lot like an Ostrich, but it’s covered in coarse, black feathers that almost look like fur. Two bright red wattles, like those of a Wild Turkey, dangle from its throat.
Cassowaries eat mostly fruit, but they’ll take just about any food that presents itself… plants, frogs, insects and the like. Females are bigger than males, sometimes a lot bigger. Unlike many other birds, males alone incubate the eggs and care for the young up to nine months.

And cassowaries are capable of making remarkable sounds:
[“Roar” of the Dwarf Cassowary].
But how about this call?
[Cassowary subaudible calls]
It’s the lowest-pitched bird call in the world, and it’s barely audible to the human ear.
I’m Mary McCann.
