Southern Cassowary - Ultra low frequency sound

[Marc Anderson <>]

The Southern Cassowary's call is apparently the lowest frequency known 
sound from any bird (if you can think of another contender I'd be 
interested to hear about it).
I recorded this sample from a captive bird in a wildlife park near 
Sydney - all I had on hand was my Canon DSLR and this is the resulting 
audio file, not great but I was happy that the miniature mic even picked 
it up. Make sure you have decent speakers or headphones for this one -

Hearing the call close up is incredible - sounds more like an large 
mammal than a bird!
