Can't always go by voice it seems, My Buff sounds like a Ban Shee when she lets out a honk or scream what ever it may be and she was 1 this past May. I keep waiting for the voice to change. Just to protect my ears.Actually!! I think what I have learned is the MALE geese have the high pitched honk and the females have the low HONK. I think... Thats how it is with Kiwi and Mango. Kiwi is very very loud and screaming but Mango HONKS
