Physical Characteristics and Identification
The Cinnamon Teal is a small dabbling duck, measuring about 14 to 17 inches (36–43 cm) in length with a wingspan near 22 inches (560 mm). You’ll notice its compact body, short wedge-shaped tail, and pointed wings, which enable agile flight.
Males weigh roughly 0.8 pounds, females 0.7 to 0.9 pounds. The bill is long, dark, and spatulate, optimized for straining food in shallow water. It has a slightly larger bill adapted specifically for straining food from water.
Males weigh about 0.8 pounds; females range 0.7 to 0.9 pounds with long, dark, spatulate bills for feeding.
Both sexes display mottled brown upperparts outside breeding season, with paler bellies. Males in breeding plumage feature uniform cinnamon-red underparts, while females are browner and plainer.
Distinctive powder-blue wing patches and iridescent green specula appear in flight. Male red irises and longer bills help distinguish them from Blue-winged Teal and Northern Shoveler, aiding precise field identification.
Sexual Dimorphism and Age Variations
Building on the physical traits that help identify Cinnamon Teal, sexual dimorphism and age-related variations provide further insight into their appearance and behavior.
Males display bright rusty-cinnamon plumage and red-orange irises during breeding, while females remain mottled brown with brown irises year-round. They are found primarily in western parts of the United States, including Montana, where they are present from spring to fall, highlighting their seasonal presence in these regions western United States.
Juveniles are duller with grey legs and dark eyes, resembling females but with subtler plumage.
Behavioral differences include males’ courtship displays and territory defense, contrasting with female acceptance signals.

Geographic Range and Migration Patterns
When you study Cinnamon Teal distribution, you’ll find their breeding range tightly focused in western North America. It stretches from south-central British Columbia down through the Great Basin and Rocky Mountain regions into northern Mexico.
Unlike many dabbling ducks, they’re absent east of the Great Plains as breeders.
You’ll notice their winter range extends from the southwestern U.S. through Mexico into Central and northern South America. Some populations winter as far south as Peru.
Migration occurs mainly along western interior routes during March-April and late summer post-breeding, involving short- to medium-distance movements. Birds travel diurnally, using wetlands as stopovers. Monitoring of migration patterns is important to understand population dynamics and conservation needs.
Year-round residents exist in southern California and the lower Colorado River region, where local status shifts seasonally.
Significantly, South American populations breed independently, linking Nearctic and Neotropical distributions.
Preferred Habitats and Ecological Niches
You’ll find cinnamon teal favoring shallow, slow-moving wetlands that are rich in emergent vegetation like rushes and sedges.
They tend to forage mainly along the water’s edge, taking advantage of aquatic invertebrates and floating plants.
When it comes to nesting, they usually pick dense, low vegetation near the water. Their half-moon shaped nests are carefully constructed from plant stems and dead grass.
Understanding these habitat preferences really shows how cinnamon teal occupy unique ecological niches that are closely tied to the structure of wetlands and the characteristics of the water.
Shallow Wetland Preferences
Because Cinnamon Teal depend heavily on shallow wetlands, they select habitats with water depths typically less than 30 to 40 cm that support dabbling and loafing behaviors.
You’ll find them favoring alkaline basins rich in emergent vegetation like baltic rush and spikerush. These plants provide essential cover and nesting sites near perennial water. Their flight pattern includes short bursts and quick, erratic movements, with males’ red bodies standing out in flight.
Their preference spans natural, managed, and agricultural wetlands. They often rely on flooded fields and irrigation ditches.
During migration, these birds seek out scarce shallow wetlands, including human-made ponds, which shows how vulnerable they’re to habitat loss.
You can observe a strong edge-oriented use, with many locations near wetland boundaries.
- Shallow ponds and marshes less than 40 cm deep
- Dense emergent vegetation around wetland margins
- Managed wetlands with controlled water levels
- Flooded agricultural fields and stock ponds
- Dynamic use of scarce wetland “islands” in arid landscapes
Cinnamon Teal are most often seen during migration in spring and fall, with some populations residing year-round in specific regions.
Feeding and Foraging Habits
Although Cinnamon Teal primarily inhabit shallow wetlands, their feeding and foraging habits are finely tuned to exploit a variety of microhabitats within these ecosystems.
You’ll observe them dabbling in shallow water, straining seeds of aquatic plants like smartweeds and pondweeds, especially outside breeding seasons.
During breeding, they shift to protein-rich aquatic invertebrates, intensifying foraging to meet reproductive demands. They also glean along shorelines and plunge to access benthic arthropods and submerged vegetation.
Their foraging concentrates in shallow marsh zones with dense emergent vegetation, maximizing seed and invertebrate availability. They predominantly use freshwater wetlands, although they can also be found in brackish wetlands in coastal areas.
Daily activity peaks during crepuscular and daylight hours, with incubating females timing foraging to reduce egg cooling risk.
Nesting Site Selection
Cinnamon Teal select nesting sites almost exclusively within freshwater wetlands across western North America, favoring large, permanent marshes rich in emergent vegetation.
You’ll find their nests mostly within 10 meters of water, often in seasonal or semi-permanent wetlands dense with grasses and bulrushes.
They prefer dead marsh grasses under 2 feet tall, which provide concealment and allow hens to tunnel to nests.
Nests are placed on slightly raised, dry ground to avoid flooding and oriented to balance sun exposure. Females add down from their breasts to line nests during egg-laying, which helps insulate the eggs.
This careful site selection reduces predation risk and increases nest survival.
Concealed beneath thick, perennial vegetation
Located on islands or grassy heights
Adapted to alkaline wetlands in arid areas
Nests lined with local rushes and saltgrass
Microclimate optimized for warmth and shade
Feeding Habits and Diet Composition
You’ll find that the cinnamon teal maintains an omnivorous diet, primarily consuming a variety of aquatic plants, seeds, grasses, and roots which constitute the bulk of its intake. Animal matter, including aquatic and semiterrestrial insects, zooplankton, and mollusks, supplements this diet, especially during breeding when females increase protein intake. They often feed in groups, following each other in tight formations, similar to Northern Shovelers, enhancing their foraging efficiency group feeding behavior.
Foraging occurs mainly by dabbling and upending in shallow wetlands, with occasional terrestrial grazing and nocturnal feeding on seeds.
| Food Category | Key Items |
|---|---|
| Plants | Aquatic plants, seeds, grasses, roots |
| Invertebrates | Aquatic insects, zooplankton, mollusks |
| Foraging Methods | Dabbling, upending, grazing, nocturnal |
| Seasonal Variation | More invertebrates during breeding season |
Social Behavior and Breeding Rituals
When late winter shifts into early spring, males intensify courtship displays to attract females, often before arriving at breeding grounds. You’ll observe ritualized preening, head-turning, and mock feeding, escalating into synchronized jump flights and pursuit chases. Females signal interest by swimming in front of males or reject suitors with head-pumping and open-bill threats. Pair bonds form seasonally monogamous, with males defending small territories near nests. Outside breeding, you’ll find small flocks growing during migration, with pairs resting closely together. Males remain vigilant, guarding mates and territory, while females focus on foraging and incubation. Nesting involves concealed sites, female incubation, and protective brooding behaviors such as distraction displays. Males court intensely in groups, increasing display vigor. Females choose mates through specific behavioral signals. Territorial males aggressively defend nesting sites. Pairs maintain close physical proximity during rest. Females incubate alone while males patrol surroundings. Cinnamon Teal typically inhabit small, shallow freshwater wetlands during breeding season, providing ideal cover and resources for nesting and raising young.
Conservation Status and Environmental Threats
You might’ve noticed that Cinnamon Teal populations have been gradually declining.
This drop is mostly because of habitat loss and the degradation of wetlands in the western regions.
It’s really important to understand how these changes in the environment affect where these birds nest and find food.
Because of this, conservation efforts are now focused on protecting and restoring wetland habitats to help stabilize and support Cinnamon Teal populations.
Population Trends Overview
Although the Cinnamon Teal currently holds a Least Concern status on the IUCN Red List, its overall population is declining. This signals potential risks that warrant your attention.
About 380,000 breeding individuals exist in North America, but droughts, pollution, and shifting climate patterns threaten their numbers. The species depends heavily on wetland networks vulnerable to contamination and hydrological changes. So, it requires vigilant monitoring.
Increasing droughts reduce critical breeding and stopover water sources. Also, reliance on polluted wastewater ponds exposes them to harmful contaminants.
Agricultural runoff introduces pesticides and fertilizers into habitats. Climate-driven range shifts impose stress from heat waves and altered precipitation.
Concentrated breeding in limited regions increases vulnerability to localized threats. You must prioritize updated assessments and conservation strategies to protect this adaptable yet imperiled species.
Habitat Loss Impacts
Since wetland loss and degradation directly reduce suitable habitat, they play a critical role in the declining Cinnamon Teal populations. You’ll find that historic wetland loss, surpassing 50% in the U.S. and over 90% in states like California, drastically shrinks nesting and foraging areas.
Agriculture, urban development, and pollution degrade water quality and food resources. Wetlands converted to deep reservoirs hinder efficient foraging. Semi-permanent and seasonal wetlands essential for breeding and molting have declined functionally, despite some surface water remaining. Monitoring has revealed that semi-permanent wetland loss indicates a systemic functional decline in waterbird habitats.
You must also consider drought, climate change, and altered hydrology, which disrupt wetland hydroperiods, reduce inflows, and increase evaporation, further fragmenting habitats.
Land use changes, including industrial agriculture, urban expansion, and heavy grazing, fragment wetlands into isolated patches. This increases energetic costs and predation risks during migration and breeding movements.
Conservation Efforts
While the Cinnamon Teal maintains a global status of Least Concern, you should recognize that regional declines raise significant conservation concerns.
North American populations have declined since 1968, complicated by limited survey coverage and data gaps.
Hunting pressures are relatively low but combined harvest data obscure species-specific impacts. In particular, harvest data in the U.S. combines Cinnamon Teal and Blue-winged Teal, hindering species-specific insights.
Habitat degradation from water management and grazing further threatens nesting success.
Pollution and climate change add complex stressors.
- Populations declining despite wide range and stable global status
- Breeding areas often outside standard surveys, limiting data accuracy
- Water scarcity reduces critical wetland habitats essential for breeding
- Livestock grazing degrades nesting cover, lowering reproductive success
- Exposure to agricultural pollutants threatens health and survival
You must support research and habitat protection to guarantee Cinnamon Teal persistence. Reliable demographic information is especially needed for informed population status assessments and management responses demographic data.
