Ducks with White Bills: Quick Identification Guide

Many birdwatchers often ask: “What’s that duck with the white bill?” whenever they spot a strange waterbird with a bright white bill. The quick answer any experienced duck enthusiast will give is American coot, because the most commonly mistaken “duck with a white bill” is actually the American Coot (Fulica americana), a dark gray to black waterbird with a striking white bill and forehead shield.

The American coot is a medium-sized bird, measuring about 34–43 cm (13–17 in) in length, with a wingspan of 58–71 cm (23–28 in). It has a short, thick white bill and a white frontal shield on its forehead, which is often features a reddish-brown spot near the top between the eyes. Males and females look very similar, though females are slightly smaller.

Although they are often mistaken for ducks, American coots are only distant relatives and belong to a completely different order. One key difference is their feet: instead of webbed feet like ducks, coots have broad, lobed toes that fold back with each step, allowing them to walk easily on land as well as swim efficiently in water.

So, if you spot a “duck” with a white bill, it’s highly likely you’re looking at an American coot. That said, are there true ducks with white bills? While ducks with white bills are rare compared to those with black, yellow, red, or blue bills, they do exist. Below are the species that are known to have white bills.

Blue Duck (Whio)

The blue duck, or Whio, is instantly recognizable by its pale pinkish-white bill, which has small fleshy flaps at the tip, an unusual feature among ducks that makes it look almost sculpted. Its slate-grey body shines with a subtle greenish tint on the head, and the chest sports delicate chestnut flecks that stand out against the darker plumage.

Beyond its striking appearance, the Whio is a true mountain specialist. It lives along fast-flowing rivers in New Zealand, using its strong swimming skills to navigate rapids that would challenge most other ducks. Unlike many waterfowl, it prefers running water over still lakes and rarely takes to the air. Males have distinctive, high-pitched calls that echo along river valleys. It is these high-pitched calls that inspired their Māori name, “Whio,”, which is a name that mimics the sound they make.

Radjah Shelduck

Another duck that has a noticeable white bill is the Radjah Shelduck. Its pale, almost glowing bill contrasts sharply with its mostly white plumage, which is accented by dark wing tips and a bold dark collar around the neck. In flight, subtle green bands appear on the tops of its wings, adding a splash of color to an otherwise monochrome look.

The Radjah Shelduck favors coastal habitats, including mangrove forests, estuaries, and shallow lagoons in New Guinea, Australia, and some of the Moluccas. It feeds on a varied diet of mollusks, insects, worms, aquatic plants, and algae, often dabbling or foraging along muddy shorelines. One fascinating feature of this species is its vocal differences: the female produces a harsh rattling call, while the male emits a soft, breathy whistle that has been described as “sore-throat” like.

Bourbourg Duck

The third duck that we can also say possesses a white bill is the Bourbourg Duck. Its soft pinkish-white bill stands out against pristine white plumage, while yellowish-orange legs add a warm contrast, giving this duck an elegant and almost regal appearance.

This large, plump breed has a long, horizontal body similar to the Aylesbury Duck, creating a solid, grounded look. Bourbourg Ducks are valued not just for their beauty but also for their productivity—they grow quickly, produce tender, flavorful meat, and lay large, reliable eggs. A hybrid of Mertchem and Aylesbury lines, they combine rapid growth, strong body size, and dual-purpose utility, making them a favorite among farmers for both meat and egg production.
