2 call ducks question

[Saaan13]

I listened to it again and can hear him. You don't mind having a drake and female?

No I’m fine with it , I thought I had all female till I questioned it yesterday , I thought why does one have a high pitch scream and the other has a low pitch chirp , I thought to myself there male and female and it’s true , I don’t mind having a male

Sounds like a duck and the other sounds like a drake to me.
