Cinnamon Teal

Identification

The cinnamon teal is a small dabbling duck easily distinguished by sexual dimorphism. Males are unmistakable, displaying a striking cinnamon-red head and body contrasted with a brown back, bright red eye, and dark bill. Females are considerably duller, with mottled brown plumage and a pale brown head; they closely resemble female blue-winged teals but have richer overall coloration, less distinct facial markings, and a notably longer, more spatulate bill. Male juveniles are particularly interesting to identify, resembling females of either species but distinguishable by their distinctive red eyes.

Cinnamon teals are compact ducks, measuring 16 inches in length with a 22-inch wingspan and weighing around 14 ounces. They undergo three molts in their first year, then maintain a schedule of two adult molts annually—a detail worth noting for field observers tracking plumage changes throughout the year.

Range & Habitat

Found exclusively in western North and South America, cinnamon teals breed in marshes and ponds across the western United States and extreme southwestern Canada. They are rare vagrants to the eastern United States, making any sighting east of their typical range noteworthy for keen birders. The species is highly migratory, with most populations wintering in northern South America and the Caribbean, though some individuals remain in California and southwestern Arizona during winter months.

Two subspecies inhabit South America, particularly the Andes region. The smaller subspecies occupies low-elevation coastal areas, including Peru and southern Argentina, while the larger subspecies resides at high elevations between 3,500 and 4,600 meters in the central Andes, representing a remarkable adaptation to different ecosystems across the continent.

Behaviour & Diet

As dabbling ducks, cinnamon teals feed at or near the water's surface, primarily consuming plant material including seeds—particularly Carex species. Their diet also incorporates aquatic fly larvae, snails, molluscs, and aquatic insects. Notably, they can employ a feeding strategy similar to northern shovelers, moving slowly in tight groups across shallow water.

Cinnamon teals are social breeders, with clutches typically containing 4 to 16 creamy white eggs measuring approximately 1.7 to 2 inches in length. Interestingly, they generally select new mates each year and are known to interbreed with blue-winged teals, their close relatives, though such hybrids are uncommon in the wild.

Best Time & Places to See It

Birdwatchers should target the western United States and southwestern Canada during breeding season for the most reliable sightings. California and southwestern Arizona offer winter viewing opportunities when some birds remain rather than migrate south. For those willing to travel further, northern South America and the Caribbean provide excellent chances during winter months, while the Andes of Peru, Bolivia, and Chile host year-round populations of the high-elevation subspecies.

Photography Tips

Male cinnamon teals offer outstanding photographic subjects with their vibrant cinnamon plumage and striking red eyes creating excellent color contrast. Early morning light at shallow marshes and ponds in breeding areas will enhance the rich tones of male plumage. Photographing feeding flocks offers opportunities to capture their characteristic slow, synchronized movements. Females require more patience to distinguish from blue-winged teals in the field, but their heavier, spatulate bills and richer coloration provide diagnostic features worth capturing for identification documentation.
