Whistling Ducks

Whistling ducks were formerly known as tree ducks, but not all like trees. They are much less arboreal than the perching ducks for instance. The name whistling duck is far more appropriate and descriptive, as all have calls ranging from distinctive high-pitched shrill sounds to clear or squeaky whistles. 

Range 

Whistling ducks live in the warmer lowland areas of the tropics and subtropics in both the Old and New Worlds. They are mostly sedentary, with movements determined by variations in the availability of water.

Recent DNA studies have shown that the White-backed Duck is most closely related to the whistling ducks, so it is included here.

Appearance 

Both sexes are alike and have similar vocal calls and displays. All have broad rounded wings, large feet, fairly long necks and legs and look rather more like small swans or geese, which they are more closely related to than most other ducks.

They differ from all the other wildfowl in the colouring of their ducklings. The downy young tend to be strongly patterned, with a characteristic light stripe that extends under the eyes and back around the nape, without any gaps. This contrasting colour pattern is particularly apparent on the duckling of the Black-bellied Whistling Duck. 

The adults range in size from the Cuban Whistling Duck, which weighs up to a kilo, down to the Lesser Whistling Duck, which weighs less than half. 

Requirements

Whistling ducks are not as commonly kept as dabbling or diving ducks. Fulvous, Black-bellied (or Red-billed) and White-faced are fairly popular in mixed collections, where they will readily feed on the same wheat and breeder pellet mix. 

Probably the best species to start with is the Fulvous as they are the hardiest. Some whistling ducks may suffer from frostbite during the winter. However, with a sheltered pond and if possible, an actual shelter, the White-faced and Red-billed species will be quite happy provided a dry substrate is provided. 

Another fairly hardy species is the Cuban, but being a little bit bigger than the other species they can be rather quarrelsome. 

Behaviour 

The pair bonds of whistling ducks are very strong. Pairs spend most of their time together and can often be seen carefully and tenderly preening each other. 

The White-faced Whistling Duck seems to be the most highly social and engages in this mutual nibbling (allopreening) frequently. This friendship between pairs is particularly obvious when they are separated as they tend to call loudly to each other until reunited. They can also be stimulated to whistle in response to an imitation of their own call, especially if they cannot see where it is coming from! 

In response to a sudden unexpected event, a flock can start a cacophony of squeals that can be quite unnerving. When frightened they sometimes stand absolutely still and quiet with their long necks stretched up as high as they will go.  

Whistling ducks are almost entirely vegetarian. They either upend or dive for food, which they can do remarkably well, or sometimes they graze. 

Nesting 

In a collection they are prepared to use a variety of different nest sites in ground cover, hollow logs, nest boxes, or sometimes even up in trees. Unlike other waterfowl, the nest is not heavily lined with down. The nest is often enthusiastically guarded.

  • Whistling ducks lay large clutches of 6 to 16 eggs. These are white or off-white and take 24-31 days to hatch, depending on species. Both sexes take part in incubating and rearing the youngsters. If left to rear their own young, they may be safer separated from the rest of the collection and away from vermin in a covered run unless you have a lot of space. As the adults tend to be so tame, this penning does not put them under any undue stress.

Waterfowl FAQ

In biology, taxonomy is the science of naming, defining and classifying groups of biological organisms on the basis of shared characteristics. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With the advent of such fields of study as phylogenetics, cladistics, and systematics, the Linnaean system has progressed to a system of modern biological classification based on the evolutionary relationships between organisms, both living and extinct. All life which has ever existed on Earth is a gradient of relatedness, and taxonomy allows us to make a phylogenetic tree showing the evolutionary relationships among various biological species or other entities, based upon similarities and differences in their physical or genetic characteristics. Think of it as a huge family tree!

Breeds and species are two groups of living things that can breed with the members of the same group. Breed is mostly used to describe groups of domestic animals while all non-hybrid life forms belong to a species. The main difference between a breed and a species is that a breed is a specific population that is selectively bred for the preservation of specific characteristics whereas a species is the largest group that can routinely produce fertile offspring through breeding. Therefore, a breed is a smaller group of animals than species. Think of a breed as a domesticated version of a subspecies, which has been subjected to artificial, as opposed to natural, selection. All domestic waterfowl are descended from a select few species: the Mallard (Anas platyrhynchos) for all duck breeds except the domestic Muscovy Duck, which is descended from the wild species (Cairina moschata) of the same name, and the Greylag (Anser anser) and Swan Geese (Anser cygnoides) for domestic geese. For a breed to be standardised it has to have proven to breed predictably for several generations.

A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic (i.e. physically expressed) traits to its offspring of many generations. An organism is referred to as true breeding for each trait to which this applies, and the term ‘true-breeding’ is also used to describe individual genetic traits.

In Mendelian genetics, this means that an organism must be homozygous for every trait for which it is considered true breeding; that is, the pairs of alleles that express a given trait are the same. In a purebred strain or breed, the goal is that the organism will ‘breed true’ for the breed-relevant traits.

Waterfowl showing is fairly easy – a bird in good condition, is pretty much in show condition. Cleaning beaks, legs and feet is desirable just before penning. It is much better to provide the opportunity for birds to clean themselves and stay clean rather than try to clean their feathers yourself. Shows are a great place to see the diverse varieties, compare the quality of your bird(s) and gain customers for your stock. All standardised varieties of waterfowl can be exhibited and if your bird’s attributes, breeding and conformation fit a breed standard, you may be taking some trophies home! Ensure your bird is a true representative of a standardised variety — unfortunately just because it was sold to you as a particular one, doesn’t necessarily mean it is, so prior research will pay dividends. The standards for each breed is published in the British Waterfowl Standards. You could attend local shows first, though novices are welcome at our Champion Waterfowl Exhibition too. Speak to exhibitors — no question is a silly question, we have all been new once so go ahead and ask away! Just remember not to disturb or distract judges while they are judging.

In the UK we face few restrictions as to which species of waterfowl we can keep. Only the (North American) Ruddy Duck is prohibited. This is to protect the endangered White-headed Duck.

As long as you keep them contained, that means not released or allowed to escape, you may keep all the other Anseriformes. All may be traded freely as long as they are individulally proven as captive bred. This means close ringed or microchipped for identification. Our native and ordinarily resident birds listed in Appendix 2 of the General Licence may be moved without a ring. Mute Swan and Egyptian Goose require an individual licence to be moved.

Our responsibility to these birds is to keep them in conditions sympathetic to a contented mental state. They should be adequately fed and watered, kept in comfortable conditions with relation to their size and normal habits, and sheltered from weather extremes. We should protect them from pain, injury and disease and allow them the freedom to express normal behaviour. We should do all in our power to protect them from fear and distress.

Essentially, these are summed up in the five freedoms of animal welfare. Expanded; four physical or functional domains of nutrition, environment, heath and behaviour surround and influence the mental state. The Five Domains are key to the highest standards of welfare.

As the British Waterfowl Association we believe that the highest standard of welfare should remain one of our core values.
