The Cinnamon Teal (Spatula cyanoptera) is a beautiful small dabbling duck found primarily in western North America. The males have unmistakable reddish-brown plumage and bright red eyes, while the females are mottled brown. Cinnamon Teals are highly social and gather in large flocks, especially during migration and winter. They inhabit marshes, ponds, and wetlands, where they feed mainly on aquatic plants and invertebrates. Cinnamon Teals exhibit interesting breeding, feeding, migratory, and social behaviors.
What does the Cinnamon Teal look like?
The adult male Cinnamon Teal has distinctive reddish-brown plumage with a pale blue patch on the upperwing. The head and neck are a rich cinnamon-red color, the breast is pinkish-brown, the belly is buff, and the back and wings are grayish-brown with speckles. The eyes are red. The bill is blackish-gray and the legs and feet are yellowish-gray.
The female is much less colorful, with mottled brown plumage throughout. Her eyes are brown. She can be distinguished from other dabbling duck females by her unique facial pattern—the crown and eye stripe are darker brown than the sides of the head. Juveniles resemble adult females.
Both sexes have a dark tail with whitish edges. In flight, the male shows pale blue forewing patches called speculums. Cinnamon Teals are 14-17 inches long with a wingspan around 24 inches.
Where does the Cinnamon Teal live?
The Cinnamon Teal has a relatively small breeding range confined to the western United States and Canada, parts of Mexico, and South America. Their breeding habitat consists of shallow freshwater wetlands such as marshes, ponds, and lakes with abundant aquatic vegetation.
The majority of the population breeds in the intermountain west from British Columbia to western Texas. There are also breeding populations in Chile and Argentina. The Cinnamon Teal winters in wetlands further south, along the Pacific and Gulf Coasts of the southern U.S., Mexico, and into Central and South America.
What does the Cinnamon Teal eat?
The diet of the Cinnamon Teal consists primarily of plant matter and aquatic invertebrates. They forage mainly by dabbling and upending to feed underwater. Their bill has comb-like projections called lamellae along the edges that help filter food from muddy bottoms.
Cinnamon Teals are omnivores and eat a variety of aquatic plants including pondweeds, wigeon grass, bulrushes, and algae. They also consume aquatic insects and larvae, mollusks, crustaceans, and occasionally small fish and amphibians. They will sometimes graze on grasses and seeds from shoreline vegetation.
During breeding season, protein-rich aquatic invertebrates become especially important for the female’s egg production and the ducklings’ growth. Cinnamon Teals are vigorous foragers and spend much of their time feeding. They gather in large flocks which facilitates finding productive food sources.
When and where does the Cinnamon Teal nest?
The breeding season of the Cinnamon Teal begins in April and runs through July. They are monogamous and form pair bonds on the wintering grounds or during spring migration for the breeding season.
Nesting typically occurs near water such as marshes, ponds, and wetlands with ample vegetation for concealment. The female builds the nest on the ground concealed in vegetation near water. It is a shallow bowl lined with grasses and down feathers plucked from her breast.
Cinnamon Teal nests are especially well-hidden, with vegetation woven over the top and an entrance tunnel along one side. This helps conceal the nest from predators. The female lays 6-12 cream-colored eggs and incubates them for 21-23 days while the male remains nearby guarding her. Once hatched, the ducklings are led by the female to water within 24 hours.
How do Cinnamon Teal ducklings develop and grow?
Cinnamon Teal ducklings hatch covered in down feathers and capable of swimming and feeding within a day. They grow and develop rapidly under the female’s care. For their first two weeks, she broods them frequently to keep them warm. The ducklings feed on aquatic invertebrates at first, then add plants and seeds to their diet as they grow.
Within 6-7 weeks the ducklings are fully feathered and begin to fly short distances. They fledge at about 45 days old. The female continues to protect and lead the brood, though the young are able to feed themselves. As they near adulthood at 10-12 weeks, the family group starts to disperse in preparation for migration. Juveniles remain with the female longer and migrate together south.
Young Cinnamon Teals grow fast but require a protein-rich diet and parental care in their early weeks to survive. The precocial ducklings mature quickly in order to migrate before winter arrives on the breeding grounds. Their rapid development enables the species’ reproduction success.
When and where does the Cinnamon Teal migrate?
The Cinnamon Teal is migratory, moving south in winter and returning to inland breeding areas in spring. Their migration timing and routes are influenced by food availability, weather, and breeding cycles.
In late summer and early fall, Cinnamon Teals start congregating in large flocks in preparation for southern migration. The ducks gradually move south from September through November. Fall migration includes stops at key wetland habitats to build energy reserves for the journey.
Their winter range extends from California and the Gulf Coast south into Mexico, Central America, and northern South America. Winters are spent in warm coastal areas with plentiful food resources. Northward spring migration occurs from February through April as the ducks return to nesting sites.
Migration routes can be lengthy, with some Cinnamon Teals traveling over 2,000 miles between breeding and wintering grounds. Their ability to fly long distances facilitates dispersal and genetic mixing of the population. Banding studies have traced migrations between Canada, the U.S., and South America.
What is the social behavior of the Cinnamon Teal?
The Cinnamon Teal is a highly social species, congregating in large flocks during non-breeding periods. They form strong pair bonds but otherwise maintain an open social structure with flexible grouping patterns. Their social behaviors facilitate feeding, migration, and protection.
During the winter, Cinnamon Teals gather in flocks numbering in the hundreds to thousands of birds. Mixed flocks may also include other duck species. These large groups provide security through vigilance against predators and the ability to locate plentiful food resources.
Pairs splitting off for breeding season rejoin flocks after nesting. Broods often merge together for rearing. As migration approaches, the flocking behavior intensifies. The flock social structure provides effective migration communication reducing individual risk.
Cinnamon Teals perform social displays such as neck-stretching, chin-lifting, and head-pumping to communicate within flocks. Vocalizations include quackings, soft rills, and whistling calls. Their strong social bonds and group behaviors are key to the species’ success.
How do Cinnamon Teals communicate?
Cinnamon Teals communicate in various ways, using vocalizations, visual displays, and body posturing. Communication serves purposes of courtship, territoriality, alarm, and maintaining social bonds. Some examples:
– Courtship calls – Males give soft whistling calls and “burping” sounds towards females during breeding. Females vocalize with a soft “purring” call to solicit copulation from the male.
– Alarm calls – Both sexes give a barking “karr” or “quark” call when alerting to danger. The female has a “croak” call to warn ducklings.
– Visual displays – Males perform ritualized displays towards females such as head-pumping and chin-lifting. Males also have threat displays like head-forward posture.
– Body posturing – Social status is communicated by dominant or relaxed posturing. Aggression is shown by bill-gaping or neck-stretching towards intruders.
– Parent/duckling – Females use soft rills and contact calls to gather ducklings. Ducklings give high-pitched peeping calls.
Vocalizations are used over longer distances while visual displays and posturing serve for close communication. Their complex signaling repertoire allows Cinnamon Teals to effectively coordinate breeding, rearing, socializing, feeding, and responding to threats.
What predators and threats face the Cinnamon Teal?
The Cinnamon Teal faces various natural predators and threats to its survival, including:
– Birds of prey: Eagles, hawks, falcons, and owls prey on adult ducks and ducklings. Northern harriers and peregrine falcons are especially significant predators.
– Mammals: Foxes, coyotes, raccoons, minks, and weasels all consume eggs and ducklings. Some may take adult ducks.
– Snakes: Garter snakes and water snakes raid nests for eggs.
– Large fish: Pike and bass take ducklings.
– Habitat loss: Wetland drainage and degradation through drought, water diversion, and human activities reduce nesting habitat.
– Pollution: Oil spills and other contaminants can poison birds and food sources.
– Hunters: Hunting pressure is moderate, with males being more vulnerable due to their bright plumage.
– Severe weather: Storms, flooding, and freezing can destroy nests and cause direct mortality.
– Disturbance: Human recreation close to breeding areas may impact nesting success.
Though resilient, Cinnamon Teals suffer nest losses to predation and flooding. Their wetland habitats require conservation to preserve populations. Maintaining undisturbed breeding areas is an important management goal.
Is the Cinnamon Teal duck endangered?
No, the Cinnamon Teal duck is not considered endangered currently. Its global population is estimated at 2-3 million individuals and its numbers are steady or increasing overall. The Cinnamon Teal has a large range across western North and South America.
The species is classified as “Least Concern” on the IUCN Red List of Threatened Species due to its abundant and widespread population. However, the Cinnamon Teal faces some conservation issues:
– It is vulnerable to wetlands loss and degradation, especially in key breeding areas like prairie potholes.
– Drought conditions in the U.S. West have reduced habitat in recent decades.
– Climate change may alter wetlands through glacial melt, increased fires, and desertification.
– Contaminants like selenium have impacted some regional populations.
– Nesting disturbances from human recreation activities are a concern.
– Subpopulation declines have occurred in areas like Washington and British Columbia.
Though still common overall, increased conservation measures for wetlands and wise water management will be important for protecting Cinnamon Teal populations into the future. Monitoring breeding populations and habitats should continue.
Conclusion
In summary, the Cinnamon Teal is a fascinating duck species exhibiting complex behaviors and adaptations. Their breeding, migratory, feeding, and social habits allow them to thrive in prairie wetland environments. Cinnamon Teals form strong pair bonds for breeding but otherwise live highly social lives congregating in large flocks for much of the year.
