Despite sharing the same name, the European Robin (Erithacus rubecula)1 and American Robin (Turdus migratorius)2 are quite different birds that belong to separate families. While both are beloved garden visitors in their respective regions, these charismatic birds have evolved independently to suit their unique environments.
Key Takeaways
- European Robins are small songbirds with orange-red breasts and belong to the Old World flycatcher family, while American Robins are larger thrushes with red-orange breasts.
- The two species are not closely related despite their similar names and some physical characteristics.
- American Robins are significantly larger, measuring 25-28cm compared to the European Robin’s 14cm length.
1. Size and Physical Appearance
The most immediately noticeable difference between these two birds is their size:
| Feature | European Robin | American Robin |
|---|---|---|
| Length | 14cm | 25-28cm |
| Wingspan | 20-22cm | 36-40cm |
| Weight | 16-22g | 77-85g |
| Breast Colour | Orange-red | Red-orange |
| Back Colour | Olive-brown | Dark grey to black |
| Face Pattern | Orange extends to forehead | White eye ring and throat |
The European Robin is a plump, small bird with a distinctive orange-red breast and face, set against an olive-brown back. Its round, chunky appearance and large black eyes give it an endearing look that has made it Britain’s national bird.
In contrast, the American Robin is notably larger, about the size of a common blackbird. It sports a darker back, ranging from grey to nearly black, with a warm red-orange breast and belly. The head is predominantly black with distinct white eye rings and throat.
