I guess should be the juvenile Collared Crow. Am I right?

It is a Collared Crow, but I think that you can see two ages of flight feathers, worn dark brown ones and less worn black feathers. I am not sure about moult pattern in this species, but if there is more than one age of feathers it can't be a juvenile (which would have all feathers the same age), most likely it is a first summer bird (i.e. hatched last year and now in its second calendar year.
