Robin

Hi Doreen, in England prefixes are historically not used for bird names, many just have single word names. When the first settlers arrived in America they saw a similar but much larger bird so they called it an American Robin, Actually the American Robin is not a Robin at all but a member of the Thrush family but the given name has stuck! Robins come in many different plumages and species throughout Europe, Asia and Australia and many different common names are used in many different languages. It is for this reason that only the scientific name is used as a specific identifier.
As far as Project Noah is concerned the Common Name can be what the user is used to using in the country where it was seen and the language they normally use. If I see this in Spain I call it a Petirrojo as well as a Robin because I know most bird names in both languages.

Did you pay attention to the continent this was seen on, Doreen? Because it looks exactly like a young robin

I do not think this is a Young Robin.
