What do we mean when we see a bird and say that it’s a robin? A simple description would be a small brownish bird with a red breast. But that’s a superficial description, and when we say “robin” what we mean depends on your location; you don’t have to look very closely to see that the European and American robins are fundamentally different.
The European robin (Erithacus rubecula, pictured above) is an Old World flycatcher, catching insects on the wing.
