Fuvolus Tree Ducks voice sexing

[Angie MI]

I have Fuvolus Tree Duck and I am wondering if you can sex them by their voice.

 

[Speceider]

Yes, you can voice sex them. Drakes have a lower whistle than ducks. You might want to check the Cornell site and listen. I do not know if they have both drake and hen whistles. Bill Hohman in the Birds of North America Series on Fulvous describe the differences.
