Greenwings peep
bluewings and cinnys quack
This is false...only the hen teal, regardless of which color does the quack. All drakes whistle.
Only the greenwings (drakes) do the peeping. All of the teal hens will quack. Never heard a bluewing or cinny drake quack or peep.
The whistle is useless for calling ducks of any variety in my opinion with the exception of a widgeon maybe. Teal are one of the most callable ducks especially in teal season with a call. You can turn them all day long with some really fast quacks easily done in a higher pitch mallard call.
One thing the whistle is good for is to throw to you buddy or partner when they are yackin on a duck call and tell them that you think the drake whistle or the peeps are what is needed to finish the birds. The best non abrasive way to get your partner to put away the kazoo.
That's why there is always one in my blind bag. Whistle ain't gonna hurt ya and it aint gonna help ya.
Just my experience. I know there will be some haters.
