These diminutive waterfowl, prized for their unique coloration and vocalizations, represent a specific variety within the Call duck breed. Their plumage exhibits a soft, diluted brown hue, overlaid with a slate-blue cast, creating a distinctive aesthetic. This combination differentiates them from other color variations found within the breed.
The popularity of these birds stems from a combination of factors, including their aesthetic appeal and their historical role as live decoys. Their compact size and relatively docile temperament also contribute to their desirability among aviculturists and hobbyists. Furthermore, selective breeding has refined their appearance and vocal characteristics, solidifying their niche within the poultry fancy.
