1. What Swan Species Undertake Migration?
Of the six to seven swan species, five are known to engage in migratory behavior to varying degrees. These species exhibit unique patterns influenced by factors like weather conditions and food availability.
- Mute Swan: While largely sedentary, some Mute swan populations migrate, particularly in Eastern Europe. Those near the Volga Delta may move towards Iran and the Middle East depending on the weather. Introduced populations in the USA and Japan migrate partially, following river deltas for food when habitats freeze over.

Whooper Swan: These swans are predominantly migratory, traveling from Iceland, Scandinavia, and Russia to the UK, Ireland, Germany, Denmark, and the Netherlands. Some venture as far south as Spain and the Mediterranean. The UK sees a significant increase in Whooper swan numbers during winter due to migration.
-
Trumpeter Swan: Many Trumpeter swan populations in Alaska and Canada migrate to the interior states. Migration is most common in the Pacific Northwest, with populations in Alaska, British Columbia, Oregon, and Washington moving down the coast and inland, seeking unfrozen waters, often traveling up to 621.37 miles (1,000 km).
-
Tundra Swan: Tundra swans from northern Canada almost always migrate. Their routes follow the Great Basin, Mississippi River, and Susquehanna River Valley in Pennsylvania. Northwestern Pacific populations often winter in Oregon and California. The Bewick’s swan, a Tundra swan subspecies, migrates from the Russian tundra to East Asia and visits the UK in winter from Scandinavia and western Russia.
-
Black-Necked Swan: Native to South America, the Black-Necked swan is mainly sedentary but disperses along rivers in search of food.
-
Black Swan: Found in Australia and New Zealand, Black swans are primarily sedentary. Some migrate from northern Australia to South Australia and Tasmania.
2. When Do Swans Commence Their Migration?
In the Northern Hemisphere, swan migration usually takes place during the winter months. Trumpeter and Tundra swans in North America may begin their migration as early as October or as late as January and February, depending on weather conditions. Whooper swans in Europe typically migrate in September and October. Migration in South America, East Asia, and Australia varies with weather conditions and frost. In particularly icy winters, some swan populations may migrate farther than usual, reaching as far as Iran and the Mediterranean.
3. What Motivates Swans To Migrate?
Food is the primary driver of swan migration. While most swan species are cold-hardy, their migration is triggered by the freezing of their food sources. Swans often migrate only as far as necessary to find unfrozen bodies of water. Their migrations can be gradual, with movements south occurring in stages as temperatures drop.

4. How Far South Do Swans Typically Migrate?
Swans are capable migrants and strong flyers. Trumpeter and Tundra swans in North America can travel over 621.37 miles (1,000 km) or more, often migrating in stages. For example, Trumpeter swans breeding in Wisconsin and Iowa migrate to Illinois, Missouri, Indiana, and Arkansas, stopping at various points along the way. Similarly, Whooper and Bewick’s swans in Europe undertake long journeys. Whoopers from Iceland travel to Ireland, Scotland, and England, a non-stop journey of about 994.19 miles (1,000 miles). Bewick’s swans migrate to the UK from the Russian tundra and Arctic regions.
5. Do Swans Migrate In Flocks?
Swans migrate in small flocks, often flying in the classic “V” formation. These flocks consist of individual swans, mated pairs, and juveniles. Trumpeter swan flocks typically include 10 to 25 birds, while Tundra swan flocks can be as large as 100 birds. Trumpeter and Whooper swans often migrate in small family groups, comprising a few pairs and their young. This is one of the few times swans exhibit gregarious and cooperative behavior, as they are typically territorial during the breeding seasons.

6. Are All Swans Migratory Birds?
While all six swan species are partially migratory, many wild populations are sedentary. For instance, Mute swans in the UK remain there year-round, and Trumpeter swans in North America do not always migrate. Black swans and Black-Necked swans typically do not migrate far, if at all. Thus, although swans are considered migratory birds, they exhibit considerable flexibility in their migratory behavior. Migration is often a necessity when lakes and rivers freeze over, preventing swans from feeding. However, swans often migrate shorter distances out of preference, particularly Black swans and Black-Necked swans.
7. Why Do Some Swans Forego Migration?
Swans may not need to migrate if they have an ample food supply in their current location. These hardy birds can endure cold weather, and their migration is primarily driven by the need to find food rather than shelter. Even the northernmost swans, such as Trumpeters, Whoopers, Tundras, and Bewick’s, do not always migrate. However, if their river and lakeside habitats freeze, they will move south in search of food.

8. Where Do Swans Spend The Winter Months?
Many northern swan populations in Canada, Russia, Iceland, and Scandinavia migrate south during winter. Their wintering grounds are typically rich in food, which is why they migrate. Most swans do not travel too far. North European swans (Whoopers and Bewick’s) often migrate to the UK and Central Europe, while Canadian swans (Trumpeters and Tundras) migrate to various parts of the USA, both coastal and inland.
9. Where Do Swans Migrate To During The Summer Season?
Migratory swans return to their breeding grounds in early spring, well before summer begins. Most swans head back from their wintering grounds before March or April to begin breeding. Migratory swans remain in their breeding grounds throughout the summer before migrating again in winter.

10. Which Swan Species Migrate To The United States?
Both Tundra and Trumpeter swans migrate to the United States from Canada. Tundra swans live in the Arctic and Subarctic regions and migrate through much of Canada, with western populations wintering in Washington, Oregon, and California. Central and eastern populations winter in Wisconsin, Minnesota, and North Dakota. Trumpeter swans migrate across Canada and the USA, with notable wintering populations found in Idaho, California, Nevada, Oregon, Utah, New Mexico, Colorado, and Arizona.
11. Do Swans Migrate Out Of The US During Winter?
No swan species leave the US during winter. Swans are virtually absent from Central America. The Black-Necked swan, native to South America, is a permanent resident of that continent.

12. Which Swan Species Migrate To The UK?
Whooper and Bewick’s swans both migrate to the UK. Bewick’s swans typically arrive from Northern Russia and Scandinavia, while Whooper swans come from Iceland and Scandinavia. These long-distance migrators travel thousands of miles, completing much of their journey non-stop. For example, the journey from Iceland to Ireland is approximately 932.05 miles (1,500 km).
13. Do Swans Migrate Away From The UK During Winter?
The UK is home to three swan species: Whooper, Bewick’s, and Mute swans. The resident Mute swan rarely migrates and stays in the UK year-round. The Bewick’s swan is both a resident and a winter arrival from the Arctic. The Whooper swan is also a winter arrival from the Arctic and Northern Europe. While some migratory swans use the UK as a staging post to head further south, the vast majority remain there during winter. Few swans leave the UK in winter, as the climate is ideal for them.
