Biography and Personal Details
The green headed duck, scientifically known as Anas platyrhynchos, is a dabbling duck that is native to the temperate and subtropical regions of the Northern Hemisphere. Known for its adaptability, this species has been introduced to various parts of the world, including Australia and New Zealand. The male, or drake, is easily identifiable by its iridescent green head, while the female, or hen, has a mottled brown appearance for better camouflage.

What Makes the Green Headed Duck So Unique?
There are several features that set the green headed duck apart from other waterfowl. For starters, its iridescent green head is not just for show; it plays a crucial role in mating displays. The brighter and more vibrant the male’s head, the more likely he is to attract a mate. Interestingly, the green coloration is not due to pigments but the microscopic structure of the feathers, which reflects light in a way that creates the shimmering effect.
Another unique characteristic is their “dabbling” feeding behavior. Unlike diving ducks, green headed ducks feed by tipping forward in the water to graze on underwater plants, seeds, and small aquatic creatures. This method allows them to forage in shallow waters where other ducks might struggle.
Why is the green coloration important?
The green coloration serves multiple purposes, including attracting mates and confusing predators. During the breeding season, the male’s vivid green head acts as a signal of health and vitality, making him more appealing to potential mates.
Do they have any unique sounds?
Yes, green headed ducks are known for their distinctive quacking sounds. The female’s loud quack is often used to communicate with her ducklings or alert others to danger. Males, on the other hand, produce softer, raspy calls, especially during courtship.
Physical Characteristics
The green headed duck is a medium-sized waterfowl, with males and females exhibiting sexual dimorphism. The males have a glossy green head, a white collar, and a chestnut-brown chest, while females are predominantly mottled brown. Both sexes have blue speculum feathers on their wings, bordered by white and black bands, which are visible during flight.

- Size: Adult green headed ducks typically measure 20–26 inches in length.
- Weight: They weigh between 1.5 and 3.5 pounds.
- Wingspan: Their wingspan ranges from 32 to 37 inches.
One of the most intriguing features of these ducks is their ability to molt twice a year. During the late summer, males lose their vibrant plumage and temporarily resemble females, a period known as “eclipse plumage.” This helps them blend into their surroundings and avoid predators.
Where Do Green Headed Ducks Live?
Green headed ducks have a wide geographic range, inhabiting various regions across North America, Europe, Asia, and even parts of Africa. They are highly adaptable and can thrive in diverse environments, from pristine wetlands to bustling urban parks.
Preferred Habitats
These ducks are commonly found in:
- Freshwater lakes and ponds
- Rivers and streams
- Marshes and wetlands
- Urban parks with water bodies
During winter, they migrate to warmer climates, often traveling thousands of miles to find suitable habitats. Their adaptability allows them to coexist with humans, making them a familiar sight in city parks and public gardens.
How do they choose their habitat?
Green headed ducks select habitats based on the availability of food, water, and shelter. They prefer areas with abundant aquatic vegetation and minimal human disturbance, although they can tolerate urban settings if conditions are favorable.
Frequently Asked Questions
1. What is the lifespan of a green headed duck?
In the wild, green headed ducks typically live for 5 to 10 years, although some individuals have been known to reach 15 years or more under optimal conditions.
2. Are green headed ducks endangered?
No, green headed ducks are currently listed as "Least Concern" by the International Union for Conservation of Nature (IUCN). However, they face threats from habitat loss and pollution.
3. Can green headed ducks fly long distances?
Yes, green headed ducks are strong fliers and are capable of covering thousands of miles during migration.
4. What do green headed ducks eat?
