Females, and males moulting out of eclipse, are very similar to females and full-plumage males respectively of Australian Shoveler; the two species do not normally overlap in distribution, but vagrant Northern are known in the range of Australian, and need great care in identification. The plumage of the female is also similar to that of a female Mallard, the bill being the major distinguishing feature.

Distribution

Breeds across northern areas of Europe, Asia and most of North America between roughly 40° to 65°N latitude. It is largely migratory, wintering across more southern regions of these continents, and also in South America and Africa south to around 5° to 10°N latitude; small numbers winter as far north as Scotland and British Columbia where mild oceanic winters allow some overlap with the breeding range.

It is a vagrant south to central South America, Australia, and South Africa, and north to Svalbard; it has also been recorded on the Azores, Madeira, the Canary Islands, and several Pacific Ocean islands.

Taxonomy

This is a monotypic species[1].

The Northern Shoveler has recently been transferred, along with several other related, mostly large-billed ducks, to the genus Spatula. These were all formerly placed in the genus Anas.

Habitat

Marshlands and overgrown ponds. Rarely on the sea. Breeds in shallow, lowland, freshwater wetlands.

Behaviour

It is not as gregarious as some other dabbling ducks in the breeding season, usually only forming small parties, but huge flocks can occur in winter on suitable subtropical and tropical wetlands (e.g. 110,000 in the Marismas Nacionales in Nayarit, western Mexico[2]).

Complex courtship display, when groups of males will head-bob to females, and perform frequent noisy aerial chases after females.

Diet

Dabbling duck, uses bill to filter food. Will eat tiny crustaceans, insects as well as seed and plant matter.

Breeding

The nest is a shallow depression on the ground, lined with plant material and down, usually close to water.

Vocalisation

Fairly quiet except during courtship. Females a mallard-like quack. Males have an odd-sounding "shukk, shukk, shukk, shukk" when displaying and in aerial chases.
