Spatula cyanoptera
Conservation status | Common and widespread. |
---|---|
Family | Ducks and Geese |
Habitat | Marshes, fresh ponds. Favors fresh or alkaline shallow lakes, extensive marshes. Generally not in coastal salt marshes. In migration, may pause on any kind of small pond or reservoir. South American races may use wider variety of habitats. |
Usually forages in shallow water, swimming forward with head partly submerged, straining food from water. One feeding bird may follow another, taking advantage of food stirred up by paddling actions of first bird. Occasionally feeds on land near water.
9-12, sometimes 4-16. Whitish to very pale buff. Incubation is by female only, 21-25 days. Young: female leads young to water after they hatch. Young find their own food; capable of flight 7 weeks after hatching. If danger threatens young, adult female may put on broken-wing act as a distraction display. Unlike most duck species, male may not abandon mate until near the time the eggs hatch, and sometimes is seen accompanying female and young brood.

Mainly seeds. Plant material in diet includes seeds of smartweeds, sedges, grasses, pondweeds, others. Also eats insects, snails, small crustaceans. In one study, migrants consumed mostly seeds and other plant material in fall, a higher proportion of animal matter (mainly insects) in spring.
Several males may court one female, making ritualized mock feeding and preening movements. Short display flights may develop into pursuit flights, with males chasing female. Nest site usually close to water among good cover of sedges, weeds, salt grass, generally well concealed. Nest is a shallow depression with some dead grass and weeds added, lined with down. Female selects nest site and builds nest.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
The future of Great Salt Lake and Bear River Bay depend on adequate long-term flows from Bear River, the largest single source of flows to the lake.
Science and planning can help ensure their continued existence.
Two-thirds of North American bird species are at risk of extinction from climate change. Urge Congress to act now.
