The Common myna (Acridotheres tristis), also known as the Indian myna, is one of the world’s most invasive bird species and poses a serious threat to South Africa’s indigenous biodiversity. Originally native to southern and south-eastern Asia, the species was introduced to South Africa around 1900 and has since spread widely across the eastern parts of the country.
Legal Status in South Africa
The Common myna is listed under the National Environmental Management: Biodiversity Act (NEMBA) as a Category 3 Invasive Species.
This means:
▪️The species is already widespread.
▪️It may not be imported, traded, or propagated.
▪️It does not warrant protection due to its harmful environmental impact.
▪️Population management is recommended.
The species is also listed among the world’s 100 worst alien invasive species because of its aggressive behaviour and ecological impact.
How to Identify a Common Myna
The Common myna is a medium-sized bird with:
▪️A chocolate-brown body
▪️Black head, throat, and tail
▪️Bright yellow beak, eye patch, legs, and feet
▪️White wing patches visible in flight
They are noisy, highly adaptable birds often seen in pairs or small groups feeding on the ground. Mynas are omnivorous and commonly roost in trees, buildings, and urban structures.
Environmental Impact
Common mynas negatively affect biodiversity by:
▪️with indigenous birds
In areas where they become established, they often displace local species and disrupt ecosystems.
What To Do When You Find a Myna Fledgling
Fledglings are often found on the ground during breeding season. Responsible action is important.
If you find a fledgling:
✔ Confirm it is a fledgling — it will be feathered but unable to fly properly, and parents are usually nearby.
✔ Leave it if uninjured — many fledglings are naturally cared for by their parents.
✘ Do not return it to a nest — the species is invasive and supporting breeding increases environmental impact.
✘ Do not raise or release it.
✔ If injured, contact local authorities or a registered wildlife rehabilitator for guidance on legal and humane action.
Why Responsible Management Matters
The spread of invasive species like the Common myna threatens South Africa’s rich indigenous birdlife. Public awareness and responsible management play a vital role in protecting local ecosystems.
By understanding the species and responding appropriately, PASA members can help safeguard biodiversity and support responsible environmental stewardship.
