Overview
The Puna Teal, scientifically known as Anas puna, is a striking waterfowl native to South America. It’s known for its striking plumage; males and females are similar in appearance, with a mottled gray body, a distinctive white face with a dark cap, and a speckled brown back. They have bright yellow eyes and a bluish-gray bill with a black tip. The Puna Teal is relatively small, measuring 19-21 inches long.
These ducks are found in high-altitude lakes and marshes, primarily in the Andean region. They are well-adapted to their harsh, high-altitude environments, demonstrating strong swimming and flying capabilities. Puna Teals are dabbling ducks, feeding on the water’s surface and occasionally upending to reach food underwater. They are also known to forage along the water’s edge.
Socially, Puna Teals are gregarious outside of the breeding season, forming large flocks. They become more territorial during breeding and are often seen in pairs or small family groups. Their calls are less pronounced than other ducks, typically emitting soft quacks and whistles. These birds are active mainly during the day, resting and preening on the shorelines.

Physical Description:
The Puna Teal is a medium-sized duck with distinctive coloring. Both males and females share a similar plumage pattern: a mottled gray body, a white face with a dark cap, and a speckled brown back. Their eyes are a striking yellow, and their bill is bluish-gray with a black tip. The legs and feet are grayish-blue.
These teals have a streamlined body adapted for swimming, with a relatively long neck for a size duck. They measure about 19-21 inches long, with a wingspan ranging from approximately 30-32 inches. The species displays little sexual dimorphism, making it difficult to distinguish males from females based on appearance alone. Their plumage provides excellent camouflage against their habitat’s rocky and reedy backgrounds.

Native Habitat:
The Puna Teal is native to South America, specifically the high-altitude Andean regions across Peru, Bolivia, Chile, and Argentina. They inhabit freshwater wetlands, including lakes, ponds, and marshes, typically at elevations above 3,000 meters (9,800 feet). These environments are characterized by cold, clear waters and abundant aquatic vegetation, providing ideal conditions for feeding and nesting.
Their habitat preferences include areas with a mix of open water and dense vegetation, which offer protection from predators and extreme weather conditions. The Puna Teal’s adaptation to high-altitude environments is unique to its ecology, allowing it to inhabit areas inhospitable to many other waterfowl species.

Diet & Feeding Habits:
Puna Teals are omnivorous, with a diet consisting of aquatic plants, seeds, small fish, and invertebrates. They feed mainly by dabbling at the water’s surface, using specialized bills to filter food. They are also known to upend in shallow water to feed on aquatic vegetation and small organisms.
These ducks often feed in groups, taking advantage of the diverse food resources available in their wetland habitats. During the breeding season, their diet shifts to include more protein-rich foods, such as insects and small crustaceans, which are essential for the growth of their ducklings. Their foraging behavior is adaptable, allowing them to thrive in the varying conditions of their high-altitude habitats.
Mating Behavior:
Mating Description:
Puna Teals are monogamous, usually forming pairs that last at least for the breeding season. Courtship behavior includes head-bobbing, wing-flapping, and soft calling. Nesting typically occurs in dense vegetation near water, where the female lays a clutch of 5-8 eggs.
The female is solely responsible for incubation, which lasts about 25-29 days. The male stays near the nest site for protection but does not participate in incubation or brooding. Once hatched, ducklings are precocial and can leave the nest within a day, guided by their mother to water. The male may rejoin the family group at this stage, helping to protect the ducklings until they fledge.

Social Structure Description:
The Puna Teal exhibits a social structure that varies depending on the season. These birds can be found in small to medium-sized flocks outside the breeding season. These groups often mix with other waterfowl species, indicating social tolerance and adaptability.
During the breeding season, Puna Teals become more territorial and pair-oriented. Pairs or small family groups are typical, with males and females defending their territory jointly. Social interactions within these groups are characterized by a mix of cooperative behaviors, such as joint nest defense, and competitive behaviors, especially among males.

Population Trend:
The Puna Teal has a stable population trend, according to the IUCN, indicating that it is not currently at significant risk. However, local populations may fluctuate due to changes in water levels and habitat conditions. The species is adaptable but remains dependent on the availability of suitable wetland habitats.
In some regions, the Puna Teal faces habitat loss and degradation threats. The conversion of wetlands for agriculture and urban development reduces the available habitat for the species. Climate change also poses a potential long-term threat, as it can alter wetland ecosystems and water availability in the high-altitude regions where the bird lives.
Population Threats:
The primary threats to the Puna Teal include habitat destruction and degradation. Wetland drainage for agriculture and urban development significantly reduces their habitat. Additionally, pollution and changes in water quality can impact the availability of food and nesting sites.
Climate change is another significant threat, as it can lead to altered precipitation patterns and water availability in the Andes. This can result in habitat changes that are unfavorable for the species. Conservation efforts are needed to address these threats and ensure the preservation of suitable habitats.
Conservation Efforts:
Conservation efforts for the Puna Teal primarily focus on habitat protection and restoration. Creating and maintaining protected areas that include wetlands are crucial for the species’ survival. These areas provide safe breeding and feeding grounds and help maintain the ecological integrity of their habitats.
In addition to habitat protection, environmental education and awareness programs are important. These programs can help local communities understand the importance of wetlands and the species that depend on them. Sustainable land-use practices and water management are also key to preserving the Puna Teal’s habitat.
Fun Facts
- Puna Teals are well adapted to life at high altitudes, with lower oxygen levels than at sea level.

- Despite their preference for high-altitude habitats, Puna Teals are strong swimmers and efficient in water.
- They have a more muted and less vocal communication style compared to other duck species, likely an adaptation to their open habitat.
- Puna Teals can be bold and unafraid of humans, often approaching closely in areas where they are not frequently disturbed.
- They are among the few waterfowl species that thrive in saline lakes and freshwater habitats.
- The Puna Teal’s plumage provides excellent camouflage against its habitat’s rocky shores and reedy banks.
- They are opportunistic feeders, able to adjust their diet based on availability and season.
- In flight, Puna Teals show a rapid wingbeat, characteristic of many dabbling ducks.
- These ducks play a vital role in their ecosystem, helping to control insect populations and disperse plant seeds through their droppings.
