The male has deep chestnut plumage during breeding season, reverting to a dark grey. The duck feeds underwater by sifting mud with its beak. The male’s white cheek patch is often distinctive from great distances. Ruddy Duck by Dorian Anderson | Macaulay Library. The Australian population of blue-billed ducks is estimated to be 12 000, although the creation of artificial wetlands such as water treatment works disguise the number occurring in natural wetlands. In preparation for laying eggs, the female builds the nest, at which time the male will mostly desert the female. After hatching, the young remain in the nest for 1 day, and are then led by the female from the nest. However, know that there are many types of ducks, and BirdEden categorizes them accompanied by their identification features and pictures to help you understand them well. [3] At 8 weeks, ducklings are of a similar size to the parents. They are even known to chase rabbits feeding on the shore. In summer, look for them swimming and diving in wetlands of the prairie pothole region and the interior West. It is colloquially known as the little bluebill or broadbill because of its distinctive blue bill. The tail feathers for both the male and female are made up of thick, spine-like shafts. Ruddy Ducks are compact, thick-necked waterfowl with seemingly oversized tails that they habitually hold upright. Breeding males are almost cartoonishly bold, with a sky-blue bill, shining white cheek patch, and gleaming chestnut body. While breeding, O. australis is secretive and wary,[10] and it will swiftly and quietly dive under water if threatened, resurfacing a large distance away, rather than escape by flying. The female will protect her brood, including hatchlings from dump clutches of other females. It is in greatest abundance in the Murray-Darling basin. [11] They include retaining sustainable water flows and developing salinity management plans and farm management plans. The female retains black plumage with brown tips all year round. The male has a slate-blue bill which changes to bright-blue during the breeding season, hence the duck's common name. Oxyura jamaicensis Most duck species have one or two characteristics that make them different. [3] There is also some evidence of the duck laying its eggs in nests occupied by other water-birds. To counteract these impacts, the Department of Environment and Conservation has devised several strategies to increase the blue-billed duck's population. [3] The female's plumage does not change throughout the year. Within one year, most have full adult plumage. A decline in bird numbers provides a warning that the natural ecological functioning of the freshwater system is at risk. Ruddy Ducks are compact, thick-necked waterfowl with seemingly oversized tails that they habitually hold upright. Any long-term decrease in the duck's population would therefore be caused by habitat loss through factors such as salinity and overgrazing more so than drought. The male duck exhibits a complex mating ritual. [3] During non-breeding season, many ducks gather in flocks totalling several hundred,[8] especially juveniles and younger adults, in open lakes or dams in autumn and winter, far from the shore. [13] Under this Act, an Action Statement for the recovery and future management of this species has been prepared. [3] O. australis does have a preference for small invertebrates, including molluscs and aquatic insects such as chironomid larvae, caddis flies, dragonflies and water beetle larvae. [3] Any variation in non-captive laying is in accordance to water-levels and hence abundance of food, a fact in contrast to Frith's description of reproduction being tied to the months between September to November. [11][16] Despite short term gains for farmers through permanent flooding, sustainability of wetland systems would decrease. Get Instant ID help for 650+ North American birds. They court females by beating their bill against their neck hard enough to create a swirl of bubbles in the water. [2][3] After the courtship ritual, and a vigorous chase, copulation follows with the female completely submerged. Because of this, these little divers often look like gray-brown or chestnut blobs with a long, rounded tail (for a duck, anyway) held up at an angle. This widespread duck breeds mostly in the prairie pothole region of North America and winters in wetlands throughout the U.S. and Mexico. The blue-billed duck has a low quack, which is seldom heard. The blue-billed duck is endemic to Australia's temperate regions. He was banded in British Columbia and 1951 and found in Oregon in 1964. Pleistocene fossils of Ruddy Ducks, at least 11,000 years old, have been unearthed in Oregon, California, Virginia, Florida, and Illinois. It appears that a female will sometimes parasitise another's efforts at incubation, described as “facultative parasitism”, by laying “dump clutches” in nests other than her own. [3] Clutch size ranges from 3 to 12, the most common being 5 to 6, according to The courting repertoire of the male is very complex and elaborative. Ruddy Ducks get harassed by Horned Grebes, Pied-billed Grebes, and American Coots during the breeding season. The specific name australis is derived from the Latin for "southern", hence Australian. [2][3], Oxyura australis is omnivorous, where invertebrates as well as seeds, buds, and fruit of emergent and submerged plants are eaten. Any long-term decrease in populations of O. australis would therefore more strongly reflect poor wetland ecosystem health, without the confounding effects of natural drought cycles. [9] The incubation is 26 to 28 days. Migration season provides some of the best bird watching opportunities, particularly for waterfowl. Outdoor Canada’s long-time hunting editor Ken Bailey has travelled all over Canada—and the world—with rifle, shotgun and fly rod in hand. When we think of ducks, we mostly picture the mallard ducks or those that are found in local ponds. The oldest Ruddy Duck on record was a male and at least 13 years, 7 months old. Energetically expensive to produce, the eggs hatch into well-developed ducklings that require only a short period of care. Blue-billed Ducks breed in secluded, densely vegetated situations with the nest constructed in cumbungi (bullrushes, Typha sp.) The male has deep chestnut plumage during breeding season, reverting to a dark grey. The species is also widespread in the south west of Western Australia. It can be difficult to observe due to its cryptic nature during its breeding season through autumn and winter.

The grebes sometimes attack Ruddy Ducks from below the water, a behavior known as “submarining.”. The feet are quite powerful, which aids in swimming and diving. The chironomid larvae are quite common in inland cumbungi swamps, and therefore make up a large portion of the diet of O. australis during its breeding season. beds or other vegetation generally over water.Nests are usually constructed from dead Typha leaves, and are sometimes thinly lined with down.Blue-billed Ducks are polygamous, and pair-bonds are short-term i.e. [2][3][8] It includes such behaviour as rolling the cheek on the back, dab-preening (also sometimes performed by females), and sousing, where the head is thrown into the water in a prone position, and the back arched as if in spasm, with possibly the legs throwing spray above the body.
