Cinnamon Teal Spatula cyanoptera


Justification of Red List Category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend may be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population is inferred to number 380,000 mature individuals (Partners in Flight 2020).

Trend justification
The population in North America is in decline (Pardieck et al. 2018; Partners in Flight 2020), but this only represents part of the global range. Populations elsewhere may be stable or have declining trends (Wetlands International 2020). Overall, a slow decline is suspected.

Distribution and population

Spatula cyanoptera has a distribution running through the Americas, occurring in Canada, U.S.A., Mexico, Colombia, Peru, Chile, Brazil, Bolivia, Paraguay, Uruguay, Argentina and the Falkland Islands (Malvinas). The subspecies borreroi, known from the east Andes of Colombia, has not been recorded since the 1950s and may be extinct (del Hoyo et al. 1992), however there are now multiple records of Cinnamon Teal (subspecies apparently undetermined) from the eastern Andes in Colombia (eBird 2021).


The quality of harvest data for the species is relatively poor due to key information being combined with Blue-winged Teal, consequently an accurate assessment of the impact of harvest on populations is missing. The suspected decline in the North American population is therefore of concern, as it contrasts with other sympatric ducks.
