Australasian Shoveler

Identification

The Australasian shoveler is a medium-sized dabbling duck measuring 46 to 53 centimetres in length. The most distinctive feature of the male is its blue-grey head marked with a striking vertical white crescent in front of the eyes. Like other shovelers, this species is named for its characteristic spatulate bill, which is longer and broader than that of typical ducks and gives the bird its alternative common names: spoonbill, shoveler, spoony, and spoonie.

Range & Habitat

The Australasian shoveler occurs across southwestern and southeastern Australia, Tasmania, and New Zealand. Historically classified as two subspecies—the Australian shoveler in Australia and Tasmania, and the New Zealand shoveler in New Zealand—it is now recognised as a single species under the scientific name Spatula rhynchotis. In New Zealand, it is known by the Māori name kuruwhengi. In Australia, the species is protected under the National Parks and Wildlife Act 1974.

This duck is specialized for heavily vegetated swamp habitats, where dense vegetation provides both shelter and feeding opportunities. These wetland environments are essential to the species' survival and breeding success.

Behaviour & Diet

The Australasian shoveler exhibits complex courtship behaviour, particularly in New Zealand where courtship begins around August. Males engage in distinctive vocalisations described as "sock, sock-sock, sock, sock-sock" while performing head-bobbing displays as they swim toward females. Courtship flights are common in morning and evening hours, where males pursue females in rapid, agile flight patterns. These aerial displays test the speed and manoeuvrability of competing drakes, with females apparently selecting mates based on performance.

Competition among males is intense, with multiple drakes often pursuing paired females. Mated males are aggressive in defending their partners, sometimes resulting in fighting. Interestingly, females will occasionally excrete on pursuing males they find unattractive. A notable characteristic of the population is a skewed sex ratio with considerably more males than females, though this imbalance is not evident in duckling broods. Males displaying extensive white breast feathers are typically unpaired; these white feathers generally indicate older birds, as first-year males rarely exhibit them. Mating can occur as early as August, though nesting typically does not commence until at least October.

Best Time & Places to See It

For observing the Australasian shoveler, visit heavily vegetated swamps in southwestern or southeastern Australia, Tasmania, or New Zealand. In New Zealand, August onwards is an excellent time to witness courtship behaviour and displays. The species' preference for densely vegetated wetlands means that patient observation in suitable habitat during breeding season will offer the best opportunities for encounters.

Photography Tips

The male's striking blue-grey head and white facial crescent provide excellent photographic subjects, particularly in good light. Capture courtship behaviour in early mornings or evenings when flights are most frequent. The bird's dabbling behaviour in swamps can be challenging to photograph due to dense vegetation, so position yourself at vantage points overlooking open water where shovelers are likely to feed or display. A telephoto lens will help you maintain distance while capturing fine details of plumage and behaviour.
