* 직박구리과의 새 (jikbakguri-gwa-ui sae): This translates to "a bird of the thrush family." Many robins are in the thrush family, so this is a relatively accurate way to refer to a robin if you don't know the specific species.
If you *knew* the specific species of robin, you would need to find its Korean name. For example, the American Robin might have a scientific Korean name, but there wouldn't be a common everyday name for it like there is in English.
