Introduction

The Ringed Teal, Callonetta leucophrys (Vieillot, 1816), is a small South American duck and the only species in the genus Callonetta. It is associated with wooded wetlands, marshes, shallow pools and small streams in parts of central and southern South America. The species is resident or makes only relatively short local movements, rather than undertaking long-distance migration.

Physical Description

The Ringed Teal is a compact duck measuring approximately 35–38 cm in length. It shows marked sexual dimorphism, with the male more boldly coloured than the female.

The adult male has a grey head, a dark crown and nape, a chestnut to reddish-brown back, grey flanks and a pinkish or salmon-coloured breast marked with dark spots. A dark line extends from the crown down the back of the neck, while the wings show a contrasting iridescent green speculum and pale markings that are especially noticeable when the bird stretches or flies. Both sexes have pinkish legs and feet.

The female is predominantly brown and more cryptically patterned. Her head is marked with pale and dark streaking, including a noticeable pale facial stripe or eye-line, and the body is mottled and finely barred. Juveniles resemble females and gradually develop adult plumage as they mature. Unlike many ducks, Ringed Teals do not undergo a strongly contrasting eclipse plumage, so adult males remain recognisably colourful throughout the year.

Range and Habitat

The Ringed Teal occurs in South America east of the Andes, including parts of southern and central Bolivia, southern and central Brazil, Paraguay, Uruguay and northern Argentina. Important habitats include swampy tropical and subtropical forest, gallery woodland, marshy clearings, secluded pools, small streams and other shallow freshwater wetlands. It may also use wet agricultural landscapes, including rice paddies, where suitable cover and feeding areas remain available.

The species is generally associated with lowland or gently wooded wetland environments. It is not regarded as a long-distance migrant, although local or seasonal movements may occur in response to water levels, food availability and breeding conditions.

Behaviour and Diet

Ringed Teals are usually seen singly, in pairs or in small groups. They are dabbling ducks that feed mainly in shallow water, often by picking items from the surface or dipping the head underwater. Their diet is not fully documented, but is thought to consist largely of seeds, aquatic plants and other vegetable matter, supplemented by small aquatic invertebrates such as insects.

They are most active during the day, with feeding also reported around dawn and dusk. Ringed Teals can perch and roost in trees, an unusual ability among small ducks, and their feet have strong claws that help them grip branches.

Pairs form strong bonds and engage in mutual preening, contact calls and other displays that help maintain the pair relationship. Courtship may include head movements, vocalisations, swimming displays and the flashing of the iridescent wing patch. Research on captive birds has documented pair-maintenance displays, coordinated calling and participation by both parents in caring for ducklings, although behaviour in wild populations requires further study.

Breeding and Nesting

Ringed Teals are cavity nesters. They commonly use tree hollows near water and may also occupy suitable artificial nest boxes. In some areas, they have been recorded nesting in large stick nests made by other birds, including Monk Parakeets.

A clutch usually contains several eggs, with published accounts commonly reporting about 6–12 eggs. The female undertakes incubation, which lasts approximately 26–29 days depending on the source and conditions. Ducklings are precocial and leave the nest soon after hatching, accompanied by the adults while they swim and feed. Field studies in Argentina have recorded repeated use of nest sites and a median clutch size of 10 eggs in nest-box studies.

Identification Tips

  • Look for a small, compact duck in a wooded wetland, shallow pool or quiet stream.
  • The male is distinctive for his salmon-pink, dark-spotted breast, grey flanks, chestnut back, dark crown and neck stripe, and green wing patch.
  • The female is brown and cryptically patterned, but the pale facial markings and contrasting wing pattern help distinguish her from uniformly brown ducks.
  • Both sexes have pinkish legs and may perch in trees, which is an important clue when the bird is seen away from the water.
  • In flight or during wing-stretching, the pale and iridescent wing markings become more conspicuous.
  • Do not confuse the Ringed Teal with unrelated small teal solely because of its size. The combination of a wooded-wetland setting, tree-perching behaviour and the male’s strongly patterned pink, grey, chestnut and black plumage is particularly useful for identification.

Conservation Status

The Ringed Teal is classified as Least Concern on the IUCN Red List. It is not currently considered globally threatened, and no reliable global population estimate is included here.

The species nevertheless depends on the continued availability of freshwater wetlands and wooded margins. Wetland drainage, conversion of natural habitat for agriculture, removal of mature trees containing nesting cavities, pollution and broader degradation of wetland systems may affect local populations. Conservation measures should therefore include protection of wetlands and gallery forests, retention of mature cavity-bearing trees, responsible management of agricultural wetlands and continued monitoring of breeding populations.

Frequently Asked Questions

Where does the Ringed Teal live?

The Ringed Teal is native to South America east of the Andes. Its range includes parts of Bolivia, Brazil, Paraguay, Uruguay and northern Argentina, where it uses wooded wetlands, marshes, shallow pools and small streams.

Is the Ringed Teal migratory?

It is generally considered resident or only locally dispersive. It does not undertake the long-distance seasonal migration typical of many northern waterfowl, although individuals may move when water levels or food supplies change.

What does the Ringed Teal eat?

Its diet probably consists mainly of seeds, aquatic plants and other vegetable material, with small aquatic invertebrates also taken. It feeds in shallow water by picking food from the surface or dipping its head below the water.

Where does the Ringed Teal nest?

It usually nests in tree cavities near wetlands. It can also use artificial nest boxes and, occasionally, large stick nests built by other birds. The female incubates the eggs, while both adults may contribute to caring for the ducklings.

How can male and female Ringed Teals be distinguished?

The male is more colourful, with a pinkish, dark-spotted breast, grey flanks, a chestnut back, a dark crown and neck stripe, and an iridescent green wing patch. The female is mainly brown with pale facial markings and more subdued patterning.

Can Ringed Teals be kept in captivity?

Ringed Teals are kept in aviculture because of their small size and attractive plumage. Captive birds require suitable water, secure housing, a balanced diet, compatible social conditions and nest facilities. Captive care should not be taken as evidence that wild birds can be collected or released, and local wildlife regulations should always be followed.
