Forest raven
Chapter 10: More birds! More Sounds!
Subchapter: More birds! More Sounds!—Australia
From page 170 in the book.
This is the same Corvus genus as that of our North American raven and crows, but how different the sounds. A deep, husky korr-korr-korr-korr, rolling his r's, then fading away. There is another in the background.
