Back on my first post I talked a little bit about the Crested Oropendolas, and the amazing sounds they make. At the time, I had forgotten about a great on-line resource called Xeno-canto, which
has a wonderful library of bird calls and songs.
If you want to hear the crazy sounds that the oropendolas make, select any of the recordings found on this page.
(Then play around on the site and find out what other sounds they have in the collection.)
