Goose vs Swan: 4 Key Differences Explained

Swans are large, majestic birds that are best known for their graceful appearance as they swim around large bodies of water.  However, they bear a striking resemblance to geese , which is why the two are often confused.  But don’t worry, as despite their similarities there are a number of key differences between them.

In this article, we’ll discover everything you need to know about geese and swans, including where they live and what they eat.  We’ll also discuss their appearance and their behavior.  But that’s not all as there’s much more to learn about these fascinating animals!  So join us as we explore all of the differences between geese and swans.

Comparing Swan vs Goose

Swans and geese are both from the family group Anatidae which includes ducks , geese, and swans.  Swans are the largest members and there are six living species which are all in the genus Cygnus .  True geese are divided into two different genera – Anser and Branta . Anser contains grey geese and white geese, of which there are 11 species. Branta contains black geese, of which there are six living species.  There are also two further genera of geese, but it is often debated as to whether these are actually geese or if they are actually shelducks.

Although there are some variations between the different species of geese, there are still some key differences to help distinguish them from swans.  Check out the chart below to learn a few of the main differences.

The 4 Key Differences Between Geese and Swans

The key differences between geese and swans are size, appearance, and behavior.  Swans are larger than most geese, but have shorter legs.  They also have a longer, curved neck and are typically always white. Additionally, swans also prefer to spend most of their time on the water, while geese are equally as happy on the land.

Let’s discuss all of these differences in more detail below.

Goose vs Swan: Size

One of the main differences between geese and swans is their size.  Typically, swans are much longer and heavier than geese as well as having a much bigger wingspan.  The wingspan of swans can be as much as a massive 10 feet, whereas geese are generally between 3 and 4 feet.  Swans are also often more than 59 inches long while weighing more than 33 pounds.  Geese generally weigh no more than 22 pounds.  Incredibly, despite swans typically being the all-around bigger bird, geese actually tend to have longer legs than them.  However, although the general rule of thumb is that swans are larger than geese, there is always an exception to the rule.  The exceptions, in this case, come from Canada, Tundra, and Berwick geese which are often larger than swans.

Goose vs Swan: Habitat

Although swans and geese share many of the same habitats – ponds, lakes, and rivers being the most common – they actually behave vastly differently while there.  This is because swans spend much more time on the water than geese do.  Despite how graceful swans are while they are swimming, they are actually fairly awkward when they are on land.  This is also why they spend more time feeding, and browsing for food while in the water.  Their main source of food is aquatic vegetation , although they also sometimes eat small fish and worms .

Geese, although able swimmers, are less awkward while on the land and are equally as at home on the water as not.  They spend much more time away from the water searching for food than swans do .  Although geese do eat aquatic vegetation, they also eat a range of grass, leaves, shoots, grain, berries, and even small insects .

Goose vs Swan: Neck

Easily the most distinctive difference between swans and geese is the shape of their neck.  Swans are known for their graceful appearance and their signature “S” shaped neck.  Their necks are long and thin which adds to this appearance.  However, when we look at geese it’s clear to see that they lack the “S” shaped curve.  Additionally, their necks are much shorter and straighter as well as being thicker.

Goose vs Swan: Behavior

Swans and geese also exhibit different behavior.  Geese are very social birds and tend to live in large flocks, even during breeding season.  However, swans prefer to keep only the company of their mate and their young.  They also have a more aggressive nature than geese, which helps them to protect themselves from predators.

The age that both birds attain sexual maturity also differs as geese mate much earlier than swans.  Most geese begin to breed around the age of 2 or 3 years while swans begin much later and don’t begin to mate until 4 or 5 years, or even as late as 7 years in some cases.
