Black-bellied Whistling Duck

Dave, Thank you so much for putting the audio on your site. It has cleared up a mystery for me and helped me identify my very poor picture of a Black-Bellied Whistling Duck. I have seen several times a little flock ususally 3 to 6 birds fly over in the morning or evening always making the same sound. It is the sound for these ducks. They seem to chatter all the time. Thank You again. Alice

That's really cool, Dave. Thanks for sharing :)

Wish we had an audio feature, so we could hear their whistle. Hopefully in the near future!
