All About Green Wing Teal Hen; By Birdieopedia
The Green-winged teal hen represents one of North America’s most remarkable yet underappreciated waterfowl species.
While male ducks often capture attention with their vibrant plumage, the female Green-winged teal (Anas carolinensis) embodies quiet resilience and evolutionary perfection. Her subtle brown coloration isn’t a design flaw—it’s a survival masterpiece that enables successful nesting and brood-rearing across diverse wetland habitats.
From Canada’s pristine lakes to Central America’s tropical marshes, these dedicated mothers navigate thousands of miles during migration, establish hidden nests, and single-handedly raise the next generation.
Their remarkable adaptability has made them one of North America’s most abundant waterfowl species, thriving in environments from agricultural fields to pristine wilderness areas. Understanding the Green-winged teal hen reveals nature’s incredible capacity for adaptation and maternal devotion.
Green wing teal hen Story
🦆 Green Wing Teal Hen
Anas carolinensis – The Unsung Hero of North American Wetlands
🎨 Physical Description
The Green-winged teal hen is a masterpiece of natural camouflage design. Her light brown overall coloration allows her to blend seamlessly into her wetland environment, providing crucial protection during the vulnerable nesting period.
Key Physical Features
Body Size
SmallCompact build, much smaller than mallard
Bill
ShortPerfect for dabbling in shallow water
Wing Speculum
GreenDistinctive green patch visible in flight
Unlike the colorful drake, the hen’s subtle appearance serves a vital evolutionary purpose. Her earth-toned plumage provides excellent nesting camouflage, helping her remain hidden from predators while incubating eggs and raising young.
🌍 Habitat & Range
Green-winged teal hens are found across the vast expanse of North America, from the Arctic tundra to tropical Central America. Their adaptability to various wetland environments makes them one of the most widespread waterfowl species.
Preferred Habitats
🏞️ Wetlands
Primary nesting areas
🌾 Marshes
Dense vegetation cover
🏔️ Shallow Lakes

Raising Ducklings
Solo parenting until fledging at 6 weeks
Clutch Size
5-16Eggs per nesting attempt
Incubation
21-23Days of brooding
Fledging
6Weeks to independence
🍽️ Feeding Behavior
Green-winged teal hens are dabbling ducks, meaning they feed by tipping forward in shallow water rather than diving. Their diet varies seasonally and reflects the nutritional demands of their lifecycle.
Dietary Preferences
🌾 Plant Matter
Seeds, grasses, and aquatic plants form the bulk of their diet, providing essential carbohydrates and energy.
🐛 Protein Sources
Insects and small aquatic animals become crucial during breeding season for extra protein needed for egg production.
🌊 Feeding Locations
Shallow waters, mudflats, and flooded agricultural fields provide diverse feeding opportunities.
The hen’s feeding behavior changes dramatically during breeding season, when she requires additional protein for egg production and energy for incubation.
⚠️ Predators & Threats
Despite their excellent camouflage, Green-winged teal hens face numerous natural predators throughout their lifecycle. However, their adaptability and reproductive success help maintain stable populations.
Common Predators
Foxes
Raccoons
Skunks
Crows
Humans
Despite these challenges, Green-winged teal populations remain robust, with the species classified as “Least Concern” by conservation organizations.
🌟 Conservation Status
Green-winged teal hens continue to thrive across North America, with stable populations and successful breeding programs. Their adaptability to various wetland habitats and high reproductive success contribute to their conservation success.
💭 The Unsung Hero
While the colorful drake gets most of the attention, the Green-winged teal hen represents the true strength of this species. Her incredible dedication to raising young, ability to blend into her environment, and adaptability to changing conditions make her a remarkable example of evolutionary success.
From the moment she returns to breeding grounds in early spring until her ducklings fledge in summer, the hen demonstrates unwavering commitment to the survival of her species. Her story is one of resilience, adaptation, and maternal dedication that continues to inspire wildlife enthusiasts and conservationists alike.
The Green-winged teal hen may not possess the flashy colors of her mate, but she possesses something far more valuable: the ability to ensure the continuation of one of North America’s most successful waterfowl species.
Some related FAQs
Look for a small, compact brown duck with a distinctive green speculum (wing patch) visible during flight. She’s much smaller than a female mallard but has similar brown coloring. The green wing patch and small size are key identifying features, especially when she’s with other ducks.
Hens nest on the ground in hidden locations near water, choosing spots with dense grass, sedges, or shrubs for camouflage. They prefer areas within 100 yards of water and often nest under logs, beside rocks, or in thick vegetation that provides overhead cover.
Male teals abandon their mates early in the breeding season to molt and prepare for migration. This behavior, called “desertion,” is common among many duck species.
The hen is fully equipped to raise ducklings alone, and this strategy allows males to focus on survival and future breeding opportunities.
Ducklings remain with their mother for approximately 6 weeks until they can fly (fledge). During this time, the hen teaches them to find food, avoid predators, and navigate their wetland environment. Once they can fly, they become independent and join other young birds.
During breeding season, hens increase their protein intake significantly, consuming insects, small aquatic animals, and invertebrates needed for egg production.
They also eat seeds, aquatic plants, and grasses. The extra protein is crucial for developing healthy eggs and maintaining energy during incubation.
These remarkable birds can migrate over 2,000 miles between breeding and wintering grounds. They breed in northern regions like Canada and Alaska, then fly to wintering areas in Central America, Mexico, and even Hawaii. Some individuals may travel from Alaska to Central America annually.
Green-winged teal hens are classified as “Least Concern” by conservation organizations, meaning their populations are stable and healthy.
However, they are protected under the Migratory Bird Treaty Act, making it illegal to hunt them without proper licenses and during designated seasons.
A typical clutch contains 5-16 eggs, with 8-12 being most common. The hen lays one egg per day until the clutch is complete, then begins incubation. Larger clutches are more common in areas with abundant food resources and optimal nesting conditions.
