Grey Call Ducks appear to be a miniature version of their breeding ancestor, the Mallard Duck. However, calls were bred to be louder than mallards in order to provide hunters a decoy when hunting other ducks.
The first records of the ingenious breeding and use of Grey Calls to call in other call ducks come from the Netherlands. However, their place of origin is disputed amongst experts. Many believe they originated in the Far East.
Being very energetic and active, pet Grey Calls are common through the US today. People raise call ducks primarily for decoration and enjoyment. Today their function as hunting tools is less typical.
They are relatively difficult to breed, but easy to care. This makes them very sought after, but at times hard to obtain. Grey Call Ducks are certain to be a prized bird in any flock that is lucky enough to have them.
