Mergansers, also known as common mergansers or goosanders in Europe, Asia, and North America, are large aquatic sea ducks found in forested areas of Europe, Asia, and North America. Common mergansers are fish-eating birds that build their nest boxes in tree holes.
Carl Linnaeus, a Swedish naturalist, published the first systematic account of common mergansers in the tenth edition of his 'Systema Naturae' in 1758.
Mergus merganser is the current binomial name for this species. The genus name, merganser, is derived from 'mergus' and 'anser', Latin for 'goose', and was used by famous Roman writers like Pliny the Elder to refer to an unidentified waterbird.
In his book 'The Birds Of America', published in 1843, John James Audubon used the term 'buff-breasted merganser' in addition to 'goosander'. So, as you can see, this bird has had a lot of different names over the years!
The aquatic merganser measures 23–28 in (58–72 cm) in length, has a wingspan of 31–38 in (78–97 cm). It typically weighs 2–4.6 lb (0.9–2.1 kg) and males are marginally larger than females, although there is some variation.
It has a crest of long head feathers, like other Mergus species, but these are typically smooth and rounded behind the head, rather than forming an erect crest.
An adult males' plumage can be distinguished easily. The body is white with a variable salmon-pink tinge, the head is black with an iridescent green gloss, the rump and tail are grey, and the wings are mostly white on the inner half and black on the outer half of adult males with breeding plumage.

Merganser Interesting Facts
What type of animal is a merganser?
Common merganser ducks are the largest freshwater duck in North America.
What class of animal does a merganser belong to?
Common mergansers are water birds belonging to the class of Aves and the order Anseriformes, family Anatidae.
How many mergansers are there in the world?
The merganser bird species comes in six different varieties, three of which are widely seen in North America. Common mergansers have a wide distribution in the northern hemisphere but their exact number around the world is not currently known. They are not rare to spot, but although they exist sparsely around oceans.
Where does a merganser live?
For all times of the year, they are mostly found in freshwater. In the summer they are found in forested countryside and on shallow yet clean rivers and lakes.
They tend to avoid deep marshes and murky waters. In the winter, they can be found on lakes and large rivers, as well as on coastal bays of the Pacific coast.
What is a merganser's habitat?
Common merganser ducks are diurnal birds that hunt in the early morning, late afternoon, and just before sunset.
When they aren't diving for small fish or their other aquatic prey, they can be seen swimming on the surface of the water or sitting on rocks in the middle of a river which is their common habitat.
They can even be found hiding among riverbank plants or (in the winter) on the edge of floating ice as lakes freeze.
Common mergansers float down their habitat of larger streams and rivers, lakes, and ponds for a few miles before flying back or, more generally, fishing their way back, diving incessantly the whole way.
Also known as goosanders, these birds can be found in both the Nearctic and Palearctic regions. Despite the fact that their numbers have been declining in North America, they are still the most common merganser there.
The common merganser range during their breeding season can be as far north as southern Alaska and Canada in North America.
In the northern and western United States, some of these birds stay all year round in the same habitat without migrating.
The North American birds spend winter in New England, the midwest, the south, and along the Pacific coasts of the United States and Canada. In the Palearctic zone, common mergansers usually breed in northern Europe, Scandinavia, Russia, and most of northern Asia.
Who do mergansers live with?
The common merganser species spends a lot of time afloat, lounging, fishing, and sleeping on the open sea, forming big or small groups. It is possible for them to form flocks of up to 75 individuals.
Common mergansers sometimes swim in small groups along the shoreline, diving with a slight jump after dipping their heads underwater to hunt for prey.
When one bird dives in front of a big party, the others always imitate the leader and vanish underwater too. They can remain underwater for up to two minutes, but most dives last for under 30 seconds.
The merganser bird species is usually vigilant, and one or two birds remain on duty to alert the flock of imminent threats at all times. When disturbed in their habitat, common mergansers tend to gorge themselves on food before fleeing.
Mergansers are clumsy on the ground, but occasionally they will run. They have a very upright posture, comparable to penguins, and will sometimes fall and slip.
How long does a merganser live?
The common merganser's lifespan ranges from 10-13 years.
How do they reproduce?
Mated pairs of common merganser males and females stay together for the whole breeding season, and sometimes for many breeding seasons after that. When a male common merganser circles a female in late winter, extending his neck forward and with his head feathers upright, this is considered to be a display of courtship.
Common merganser ducks' breeding season comes once every year and these birds prefer breeding in a tree cavity. Between May and June (their breeding season), the female lays between nine and 12 eggs.
The incubation period is 30-35 days long and the eggs are 2.52 in (64 mm) long. These eggs are light yellow, ivory, or white buff in color and the young birds accompany their mothers to feeding sites after hatching.
As soon as these common merganser chicks leave their nest boxes, they can learn to swim and feed quickly, but for the first few days, they eat predominantly from the water's surface.
The young birds are expert divers in just eight days and adult females leave the immature common merganser chicks just 30 to 50 days after hatching before they learn to fly. After being left, these young chicks follow other young birds, forming a group together.
What is their conservation status?
While the impact of the sport of fishing is a concern in some regions, this species' conservation status is Least Concern according to the IUCN. However, wetland degradation, pesticide, and lead pollution may pose a danger to these birds in the long run.
Merganser Fun Facts
What do mergansers look like?
These ducks have a red bill and a dark green body. Females have a gray body and the young birds have a white chest and rusty-cinnamon brown head. Males' non-breeding plumage looks very similar to the female plumage. The birds have large white spots on their upper wings and these are typically larger in adult males.
How cute are they?
Common mergansers are really cute birds with their clumsy walk and behaviors. Truly adorable!
How do they communicate?
When swimming in the sea, common mergansers use their excellent eyesight to locate prey underwater. When the water is murky, they will even hunt food by probing underwater crevices.
Males and females are mostly mute during courtship, but males make certain calls, including hoarse croaking noises and a twang that sounds like a guitar chord.
Females have a harsh 'karrrr-karr' call that can be heard during courtship or to alert others of a predator.
It has been recorded that two or more birds dive from flight into the water with a specific body position, making an audible hollow sound, but the intent of this action is unclear.
This flight into the water might or might not link to the breeding season of the bird, or this flight into the water by a common merganser duck might also be part of some sort of common merganser call during winter.
How big is a merganser?
These North American birds measure 23-28 in (58–72 cm) and the common merganser wing-span ranges from 31–38 in (78–97 cm).
How fast can a merganser fly?
When it comes to the speed of these merganser birds, they are among the fastest ducks in the world. However, in a common merganser vs red-breasted merganser comparison, the red-breasted merganser holds the fastest flying speed of 81 mph (130 kph).
The speed of the common merganser is not officially recorded, but we know that their speed is not too far behind.
How much does a merganser weigh?
The common merganser's weight ranges between 2-4.6 lb (0.9–2.1 kg).
What are their male and female names of the species?
Common merganser drake is the name given to the male of the species while a female common merganser is called a hen.
What would you call a baby merganser?
Young common mergansers can be called 'common merganser ducklings' or 'chicks'.
What do they eat?
These North American birds eat fish, mussels, shrimp, and salamanders. Adult males have been known to consume fish up to 1 ft (30.48 cm) long. Ducklings consume more marine insects when they are young and they start eating fish as they grow up.
Are they friendly?
These are not the most friendly species and can be aggressive.
Would they make a good pet?
The common merganser (Mergus merganser) species has not been domesticated in any way by humans. They are wild birds and would not be good pets.
Did you know...
One of the most interesting common mergansers facts is that these birds will capture fish by diving directly underwater and staying submerged for up to two minutes. This allows them to effectively capture fish and they resurface in order to swallow their prey, which they turn around and swallow headfirst.
This technique protects the merganser from being harmed by the spiny fins of any fish.
Because of their long guttural call, which can be heard a half-mile away, hooded mergansers are often referred to as 'frog ducks'.
Single females have been seen with over 70 ducklings at one time, suggesting that common mergansers form crèches. Merganser ducklings in the water can form a tight-knit community that resembles a swimming muskrat. Sharp-shinned hawks, for example, are often be tricked by this instinctive action.
The common merganser (Mergus merganser) is larger than the common goldeneye.
Juvenile common merganser birds look very similar to adult female mergansers in terms of appearance, whether they are male or female themselves.
How long can a merganser stay underwater?
Common merganser birds capture fish by diving directly under the water and can stay submerged for up to two minutes.
Can you eat mergansers?
Yes, but common mergansers eat fish, which imparts a heavy taste to their meat that many people dislike. Mergansers aren't the most appetizing food, which is why most people stay away from them.
