Robins are a familiar sight in backyards and gardens across North America and Europe. With their bright red breasts and cheerful birdsong, they are one of the most recognizable birds in these parts of the world. But what about Asia? Do these iconic songbirds exist on the other side of the world?
What is a Robin?
The name “robin” is applied to a number of species of small passerine birds in the genus Erithacus. The European Robin (Erithacus rubecula) and the American Robin (Turdus migratorius) are the most well-known species referred to as robins.
The European Robin is found throughout most of Europe and parts of North Africa and Western Asia. It has olive-brown upperparts and a distinctive red breast and face. The American Robin is found throughout most of North America. It has gray-brown upperparts and reddish underparts that are paler on the belly.
Both species nest in similar habitats, including gardens, parks, and woodlands. They forage on the ground for insects, worms, and fruit. Though not closely related (they belong to different genera), the European and American robins occupy a similar ecological niche on their respective continents.
Range of the European Robin
The European Robin has an expansive range across Europe and Western Asia. It is found throughout the British Isles, across Europe from Portugal to Russia’s Ural Mountains, and south to Morocco, Algeria, and Tunisia.
In Asia, the European Robin occurs in parts of Western Asia including Turkey, Georgia, Armenia, Azerbaijan, Syria, Lebanon, Israel, Jordan, and Iran. It is mostly resident across this range, though some populations migrate short distances.
The map below shows the breeding range of the European Robin in green and the wintering range in purple.
As this map illustrates, the European Robin can be found across a broad swath of Europe and Western Asia. Its range extends into the Middle East but does not reach deep into continental Asia.
Range of the American Robin
The American Robin has an extensive range across North America. It breeds throughout Alaska, Canada, the continental United States, and even down into central Mexico.
American Robins are partially migratory. Northern populations migrate south for the winter, while southern birds are mostly resident year-round. Some robins may migrate from the coldest parts of Canada down to southernmost Mexico.
The map below illustrates the breeding (green), wintering (purple), and year-round (blue) ranges of the American Robin.
As this map shows, the American Robin occupies a broad range across North America. However, it is limited solely to the Americas and does not cross into Asia.
Presence of Robins in Asia
So are there any true robins found in Asia? The short answer is no. Neither the European Robin nor American Robin occur naturally anywhere in Asia.
This is because Asia already has its own native thrushes that occupy similar ecological niches as the European and American robins. Examples include the Oriental Magpie-Robin, the Japanese Robin, the Ryukyu Robin, and the Red-flanked Bluetail. These Asian species belong to their own distinct genus, as opposed to the European Erithacus or American Turdus.
There are also other types of chats and thrushes found across Asia that may sometimes be locally known as “robins” but are not true robins in the ornithological sense. For example, the Himalayan Red-flanked Bush Robin is sometimes referred to as the “Himalayan Robin” but is not closely related to the European or American species.
Introduced Robins Outside their Native Range
While there are no native robin species in Asia, European Robins have been introduced and established small populations in some parts of Asia.
European Robins were introduced to Australia in the 19th century and have naturalized around Melbourne and other parts of southeastern Australia. They have also been introduced to New Zealand where they occasionally breed but have not become fully naturalized.
Additionally, small numbers of European Robins have been observed wintering in parts of Japan, apparently after migrating from eastern Russia. However, there are not yet any firmly established breeding populations of European Robins in Japan or anywhere else in Asia outside of southeastern Australia.
Table of Robin Introductions in Asia
Location | Robin Species Introduced | Status |
---|---|---|
Southeastern Australia | European Robin | Established breeding populations around Melbourne |
New Zealand | European Robin | Occasional breeding but not fully naturalized |
Japan | European Robin | Small numbers wintering but no breeding populations |
As this table demonstrates, the European Robin has been sparingly introduced in parts of Australia, New Zealand, and Japan, but remains restricted in distribution and has not become widespread across Asia.
Vagrant Robins in Asia
Very rarely, individual robins may turn up in Asia as vagrants – birds outside their normal range. For example, there are a handful of records of American Robins vagrants showing up in far eastern Russia, Alaska, and Aleutian islands.
These cases represent lost and wayward individuals blown off course during migration. Given the great distances, it is unlikely they would successfully breed or establish populations so far from their regular North American range and habitat.
Similarly, there are also a few records of European Robins showing up as vagrant visitors to more distant parts of Asia such as India, Southeast Asia, and China. Again, these are assumed to be cases of individuals lost during migration, not evidence of undiscovered populations in those regions.
Why are Robins Absent from Most of Asia?
The absence of robins across most of Asia is due to biogeography and ecological differences between Asia and Europe/North America where robins naturally occur.
Asia already has a diverse set of endemic thrush species filling similar ecological roles to robins. With these niches already occupied, true robins would face competition and difficulty establishing themselves in most Asian habitats and ecosystems.
There are also geographic barriers such as the Himalayas, expanses of desert, and open ocean which limit the natural spread and dispersal of robins from Europe/North America into deeper parts of Asia. So robins are essentially absent from Asia for similar reasons as why other species have restricted distributions – competition, geographic barriers, and ecological differences.
Conclusion
In summary, true robins in the genera Erithacus and Turdus are restricted to Europe, North Africa, the Middle East, and the Americas. They do not naturally occur anywhere else in Asia besides small parts of Western Asia.
The European Robin has been sparingly introduced in southeastern Australia and New Zealand but has not become widespread. Occasionally, vagrant robins may stray into other parts of Asia but do not establish due to unsuitable habitat and competition from local thrush species.
So while Asia has its own diversity of native chats and thrushes, the iconic robins of Europe and North America are generally absent, except for the far western fringe of the continent. Robins remain emblematic birds of Europe and the Americas but have not naturally expanded their range deeply into Asia.
