Anas acuta, commonly known as the northern pintail, is a species of dabbling duck found in various regions around the world. In the context of the environment, Anas acuta plays a significant role in wetland ecosystems and serves as an indicator of environmental health. This species is noted for its elegant appearance and migratory patterns, which are crucial for the biodiversity and functioning of wetland habitats.


Anas acuta is a medium-sized duck with a distinctive long neck and pointed tail, giving it its common name, the northern pintail. The males are particularly striking with their chocolate-brown heads, white breasts, and grey bodies, while females are mottled brown, providing excellent camouflage. These birds are highly migratory, breeding in the northern regions of North America, Europe, and Asia, and wintering in more temperate areas across the globe.

The presence of Anas acuta in a wetland is a strong indicator of the ecosystem's health. They rely on clean, unpolluted water bodies rich in vegetation and invertebrates. Their migratory patterns also make them important for the dispersal of aquatic plants and the maintenance of ecological connections between distant regions. Unfortunately, their dependency on wetlands also makes them vulnerable to habitat destruction, pollution, and climate change.

Application Areas

Anas acuta is relevant in various environmental contexts:

  • Biodiversity Indicators: The presence and population health of northern pintails can indicate the overall health of wetland ecosystems.
  • Wetland Conservation: Protecting habitats critical to the survival of Anas acuta helps ensure the preservation of diverse wetland species and ecological processes.
  • Ecosystem Services: As part of the wetland ecosystem, pintails contribute to nutrient cycling, seed dispersal, and the control of invertebrate populations.

Well-Known Examples

Notable examples of Anas acuta and its environmental significance include:

  • North America: The northern pintail is a common sight in wetlands across Canada and the United States during breeding and migration seasons. Efforts in these regions focus on preserving critical breeding and stopover habitats.
  • Europe: In the United Kingdom, conservation programs aim to protect the wintering grounds of pintails, which are vital for their survival during colder months.
  • Asia: Japan and other East Asian countries see significant populations of pintails during winter. Conservation initiatives often focus on maintaining and restoring wetland habitats to support these migratory birds.

Treatment and Risks

Anas acuta faces several environmental risks:

  • Habitat Loss: Wetland drainage for agriculture and urban development significantly reduces available habitats for pintails.
  • Pollution: Water pollution from agricultural runoff, industrial waste, and other sources can degrade the quality of wetland habitats, affecting the food sources and health of pintails.
  • Climate Change: Changes in climate patterns can alter migratory routes and the availability of suitable breeding and wintering habitats.
  • Hunting: Although regulated in many areas, hunting can still impact pintail populations, particularly if not managed sustainably.

Examples of Sentences

  1. Anas acuta populations have declined due to extensive wetland drainage for agricultural use.
  2. Conservationists are working to protect Anas acuta by restoring wetland habitats across its migratory range.
  3. Climate change poses a significant threat to Anas acuta, as shifting weather patterns can disrupt their migratory routes.

Similar Terms

  • Anas crecca: The common teal, another species of dabbling duck with similar habitat requirements.
  • Anas platyrhynchos: The mallard, a widely distributed and well-known dabbling duck.
  • Mareca penelope: The Eurasian wigeon, which shares overlapping habitats with the northern pintail.


Anas acuta, the northern pintail, is a crucial species within wetland ecosystems, serving as an indicator of environmental health and contributing to biodiversity. Its survival is closely tied to the condition of wetlands, making conservation efforts essential to protect this elegant and migratory bird from threats such as habitat loss, pollution, and climate change.
